How to treat currants from spider mites. Spider and kidney mites on currants: signs of the appearance of pests and measures to combat them. Bud mite on currant

The article tells about currant pests and ways to deal with them with chemical and folk remedies.

Currant bud mite

Description of the pest. A microscopic pest of currant that is difficult to see with the naked eye. It is clearly visible in the spring when the tick moves, but in infected kidneys it can only be seen under a microscope.

Ticks look like very small white worms; they live, hibernate and feed in currant buds. In spring, at an air temperature of + 5-6 ° C, females lay eggs inside the kidneys. After 7-14 days, larvae emerge from them, which continue to feed inside the kidney. During the season, 3-4 generations of pests hatch, which in the spring come out in search of a new habitat. In one kidney there can be 3-5 thousand larvae and adults.

In the spring, during the period of leafing and budding, the mites come out and infect neighboring healthy buds. At this time, they can be seen. The migration period of ticks lasts 25-30 days, but they are especially massive in search of a new food base during the flowering of blackcurrant. Ticks can be carried to neighboring bushes by wind, garden tools, or on the gardener's clothes.

The nature of the damage. It affects blackcurrant, but it can, with a strong reproduction of the pest, appear on red.

Affected kidneys swell, become rounded, resembling a small head of Brussels sprouts. The more pests are inside the kidney, the more it rounds. Affected buds become pale yellow in color, do not bloom in spring, but dry out or rot. With a strong infection of currants, diseased buds are noticeable by the end of summer. In mite-damaged bushes, yields are noticeably reduced.

Control measures. The difficulty in controlling the kidney mite lies in the fact that the pest is well protected by kidney scales from the action of pesticides. During the flowering period of currants, when tramps come out, the use of chemistry is highly undesirable.

When swollen buds appear on the bushes, they are harvested by hand in autumn or spring before flowering. In case of severe damage, the branch is cut out entirely. If the entire bush is affected by the tick, then it is completely cut out, the young shoots that have grown over the summer will be free from the pest.

How to treat currants against kidney mites.

1. During the period of budding, the bushes are sprayed with a solution of colloidal sulfur, or dispersed sulfur. Spraying is done 1 time in the spring. Currants are processed on warm days, since sulfur preparations are effective only at temperatures above 20 ° C.
2. Spraying with Thiovit Jet. It contains sulfur and has moderate activity against mites. Processing is carried out when the leaves bloom.
3. Cover the infected bushes with a film, tying it at the base, and set fire to a sulfur bomb inside. Leave the film for 24-36 hours.
4. Spraying bushes with Apollo. Acoricide is used during the period when ticks come out of the kidneys. It destroys eggs and larvae and neuters adults but does not kill them. The treatment is carried out once during the period of bud break.
5. Processed by Neoron. Acoricide of contact action, is used during the period when ticks come out of the kidneys. Active against adults and larvae.

Preparations against gnawing and sucking pests do not work at all on the kidney tick.

Folk remedies.

1. During the period of nomination of the buds, the bushes are sprayed with an infusion of garlic. 150 g of crushed garlic is poured into 10 liters of water and currants are processed. Processing is carried out three times in 5-6 days.
2. In early spring, before the buds swell, currants are poured with boiling water. Sleeping kidneys will not be harmed, and ticks that are sensitive to high temperatures die.
3. Decoction of onion peel. 200 g of husks are poured into 3 liters of water and boiled for 15 minutes. Filter, bring the volume to 10 liters, spray the currants during the period of leaf blooming and after flowering.

Prevention.

1. Planting varieties resistant to bud mites: Zagadka, Michurin's Memory, Sevchanka, Miracle, Alexandrina, Binar, Belarusian Sweet, Zusha, Dobrynya, Orlovsky Waltz. Varieties Dachnitsa, Exotica, Gulliver, Green Haze, Chebarkul, Lazybones are unstable to ticks. Most varieties of red and white currants are resistant to bud mites. There are susceptible varieties, but these types of currants are affected by the pest much less frequently than black currants, and only when there is a lack of food supply for the tick, or if it spreads very strongly over the site.
2. Planting between bushes of garlic or perennial onions. Their scent repels pests. Plants are planted in curtains and plantings are left for the winter.

It is very difficult to deal with a kidney tick. All bushes must be inspected in the fall and early spring for the presence of affected buds. If they are found, immediately take measures to eradicate the pest.

leaf gall aphid

In the photo gall aphid.

Description of the pest. Small insects 2-3 mm long, yellow in color, have very delicate integuments of the body. The pest settles on the underside of the leaves, where it forms colonies. More often it affects white and red currants, but it can also attack black. The eggs overwinter, which the female lays on the bark of annual growths next to the kidneys. In the spring, larvae emerge from the eggs, which feed on young leaves and tender, juicy green shoots. By the middle of summer, wings form in the aphid, and it moves from currants to herbaceous plants. By autumn, the aphid returns to the currant, where the founding females lay their eggs. During the season, up to 10 generations of pests appear.

The nature of the damage. A sucking insect that infects the tops of shoots and young currant leaves. On the upper side of the leaves appear numerous tuberous swellings of red or brown color, which are called galls. Depressions appear on the underside, in which single insects or aphid colonies sit and suck the juice from young tissues. With severe damage, the leaves curl up and dry out, and the pests move on to healthy leaves.

With a massive infection, aphids can destroy young bushes. On an adult fruit-bearing currant, the yield decreases sharply, the young growth is insignificant, thin and weak, with severe damage to aphids, it can dry out.

Control measures at the same time they are also preventive measures against aphids. Since many generations of pests appear during the summer, treatments are carried out 4-5 times per season, starting in early spring and ending in September. At one time aphids cannot be destroyed.

Chemical means of fighting aphids.

1. Spraying leaves from the underside with insecticides Inta-Vir, Iskra, Karbofos, Actellik, Kinmiks, Aktara. The first treatment is carried out in the spring when the buds open, but before flowering begins; 2nd - after flowering; 3rd - after picking berries, 4th in mid-late August, when the aphid returns to the currant.
2. Treatment of currant bushes with Fitoverm biopreparation, it is non-toxic and can be used during the fruiting period. Spraying is carried out throughout the season with an interval of 14-17 days.

After 2-fold treatment with insecticides, if there is no further development of the pest, you can proceed to the use of folk remedies for currant protection.

Folk remedies for the fight against aphids.

1. Spraying young shoots and leaves with soda solution from the underside. The body of the pest is very delicate and in contact with the treated leaves, it gets severe burns and dies. To prepare a solution, 3-4 tablespoons of soda are poured into 5 liters of water and the leaves are sprayed on the tops of the shoots from the underside. With the same solution, you can simply wash the top of the shoots.
2. Infusion on hot pepper. Finely chop fresh hot pepper, add water, bring to a boil and simmer for 30-40 minutes, leave for 1-2 days. Dilute the resulting concentrate in 10 liters of water, add laundry soap. Spray currants when aphids appear. You can simply dilute a bag of dry red hot pepper in 200 ml of water and insist for 2 days. Precautions must be taken when preparing the concentrate, as evaporation of pepper can cause irritation and burns to the eyes, respiratory tract and skin. Processing is carried out in gloves, a mask and goggles.
3. Dilute 10 ml of 5% iodine in 5-7 liters of water and spray the bushes when a pest appears.

Prevention is to remove all weeds on the plantation and use natural enemies of aphids. Ladybugs feed on aphids; to attract them, daisies, tansy, and yarrow are planted in the country. The natural enemies include lacewings.

It is extremely undesirable to cut the shoots damaged by the pest, since it is on their border that the fruit branches of the red and white currants are laid.

shoot aphid

Description of the pest. Small insect 1.1-1.8 mm long, light green in color. It affects red, white, black currants and gooseberries. Also, its colonies may appear on fruit trees. The eggs hibernate on the bark near the buds, in April-May the larvae emerge from them and feed on the juice of the buds, young leaves and petioles. At the beginning of summer, winged female settlers appear, which, flying away, infect neighboring plants. During the season, 6-8 generations appear.

The nature of the damage. It affects the tops of the shoots, where young and juicy leaves and young growth are located. The leaves curl into clumps, inside which are colonies of aphids. As the branches grow, leaf clumps remain in the middle of the shoots, unless aphids damage the newly growing tops.

Aphids on currants.

The development of one-year growth slows down, the petioles of the leaves are bent.

How to process currants. It is necessary to fight aphids systematically, one treatment is not enough.

1. Spraying currant bushes with Fitoverm prevents the attack of the pest and causes the death of existing colonies. The duration of the protective action of the drug is 14-16 days.
2. In a mass attack, Aktara, Biokill, Kinmiks are used.

Folk remedies aphid control is very effective with moderate infestation. Shooting aphids on currants can be destroyed by using means of contact action that cause damage to the integumentary tissues of the pest. For these purposes, infusions are used.

1. 10 g of white mustard are infused in 1 liter of water for 2 days, then the concentrate is filtered. 200 g of the infusion is diluted in 10 liters of water and the currants are sprayed, or the tops of the shoots are simply dipped into the solution.
2. Tobacco dust or shag. 400 g of raw materials pour 5 liters of boiling water, leave for 48 hours. Strain, bring the infusion to 10 liters, add laundry soap as an adhesive. Treat damaged shoots from the underside. After 7-10 days, the treatment is repeated.

Prevention. Attracting ladybugs and lacewings to the site, which feed on aphids.

Removal of ants from the site that contribute to the resettlement of aphids.

Description of the pest. Damages blackcurrant berries. The caterpillar hibernates in a web cocoon in the ground. In the spring, during the flowering of the currant, adult insects come out. Females choose the largest ovaries and lay one egg at a time at their base. Inside the green berries, a caterpillar emerges from the egg, which feeds on seeds without damaging the flesh. Then she gnaws through the peel, usually at the stalk, goes down on the cobweb and goes into the soil for wintering. One generation of pests appears per season.

The nature of the damage. The caterpillar eats away the seeds, filling the berry with excrement. Damaged berries turn black earlier, grow and become ribbed from round ones. Such fruits stand out sharply against the background of still green berries. They are somewhat larger than the usual fruits of this variety, irregular in shape. After the caterpillar leaves, the berries fall off or rot.

How to deal with this pest.

1. Collection and destruction of browned and blackened ribbed berries during the period when the bulk of the fruit is still green.
2. In case of mass defeat, Agravertin is used to combat the sawfly. It paralyzes the insect, and after 1-2 days it dies. Processing is carried out once when tying berries.
3. Spraying currant bushes with Fitoverm during fruit set.

Prevention. In the presence of a pest in late autumn, they dig up the ground under the bushes. Spider cocoons appear on the surface and the caterpillars wintering in them die.

Glass currant

The glass case is one of the most dangerous currant pests.

Description. A very dangerous pest of currants. Damages all types of currants and gooseberries. Caterpillars hibernate in damaged branches. They are quite large, up to 2 cm long, white, with a beige head. In early May, the caterpillar gnaws its way out, leaving only a thin film of bark, and pupates. At the end of May, a butterfly flies out through this hole. It has glassy-transparent wings with black veins and an orange border, with a wingspan of about 23 mm, the body itself is bluish-black. Butterfly years last 30-35 days. During this time, they lay up to 60 eggs on the bark at a height of 40-70 cm. Caterpillars emerge from the eggs, which gnaw their way through the bark and feed on the core.

The nature of the damage. The caterpillar eats away the core of the branches, gradually descending down to ground level. At the initial introduction of the pest, there are no signs of damage, the branches look healthy, and only when pruning can one notice the course. In the second year, the leaves on the shoots are crushed, there are fewer berries on the damaged branches. Shoots dry, starting from the tops. They are very clearly visible after the flowering of the currant.

Pests eat away the core of currant stalks.

Pest control. Glassware is very dangerous. If you do not start to fight it in time, then the bushes may die.

1. Pest control consists of pruning damaged branches to healthy wood. All cut shoots must be burned as soon as possible.
2. During the flight of butterflies, the bushes are sprayed with Iskra, Aktellik.

Folk remedies to combat this pest are very effective, they can prevent the appearance of glass cases on currants.

1. During the flight of butterflies, small containers with blackcurrant jam are hung on the bushes. This helps to catch butterflies.
2. During the mass summer of butterflies, the bushes are sprayed with infusions that have a strong smell (onion, garlic, orange peels, stepchildren of tomatoes, needles). You can spray with tar (1 tsp per 5 liters of water). Unfamiliar odors repel pests.

Prevention.

1. Use of healthy planting material. You can not take layering and cuttings from the bushes where the glass was seen.
2. Do not buy seedlings with withered leaves, drying tops.
3. Removal of all diseased and damaged branches.

With a strong pest attack, the currant bushes dry out. To save the variety, all branches are cut to ground level and if the roots are viable, they will give young shoots.

gooseberry moth

Description of the pest. A large night moth, the front pair of wings is light brown, the back is light ash. During the day, she hides in the bushes, at dusk and flies at night. The caterpillars are also quite long - 10-11 mm, at first they are yellow-white with a black head, and then turn green. Caterpillars go into the ground to a depth of 3-4 cm, where they pupate. Wintering stage - pupa. At the end of April (in the southern regions 2 weeks earlier), butterflies fly out of the pupae, the flight of which lasts 1-1.5 months. Females lay their eggs inside the inflorescences, on the ovaries and leaves.

One generation is born per season. Damages red, white currants and gooseberries. Less common on blackcurrants, sometimes attacking raspberries.

The nature of the damage. The caterpillar is very voracious, damages the berries, eating out seeds and pulp. Then it moves to the next berry. A thin web stretches from fruit to fruit. When delayed with protective measures, the pest weaves a cocoon of 10-12 damaged berries. Berries in a cocoon gradually rot or dry out. If you stir up the cocoon, then in the juiciest berry you can also find a caterpillar.

Control measures.

1. Collection and destruction of spider cocoons. The faster you can collect pests, the less crop loss will be. Collected cocoons are burned or poured with boiling water.
2. Immediately after flowering, the bushes are sprayed with insecticides (Spark, Aktellik, Karbofos).
3. Immediately after flowering, currants are treated with Senpai systemic contact insecticide. The drug has proven itself as a means of combating various types of pests.

Folk remedies for fighting fire.

1. Newspapers, cardboard, film, everything that prevents butterflies from reaching the surface are laid out under the bushes. After flowering, the protective material is removed.
2. 7-10 days before the start of flowering, the ground around the bushes is sprinkled with dust powder. You can water it with a 12% solution of dust.
3. Dusting bushes with tobacco dust.
4. 10 g of elderberry insist in 1 liter of water for 48 hours, then strain. Pour 20 ml of the drug with 700-800 ml of water and treat the shrubs.

All spraying with both chemical and folk remedies is carried out in the evening, when the butterflies are most active.

Prevention.

1. Digging the ground under the bushes by 10-15 cm.
2. In autumn, the ground under the bushes is mulched with peat or simply poured an additional layer of earth 15-17 cm high. The soil is taken from other parts of the garden where there are no pupae. In the spring, the butterfly will not be able to come to the surface and will die. At the end of the flowering of gooseberries and currants, the bushes are unraveled.

gooseberry moth

A beautiful butterfly, but it turns out to be a dangerous pest.

Description of the moth. Another common pest of currants. Damages gooseberries and black currants. In addition, it can attack an apple tree, pear, plum, bird cherry.

Butterflies are very large, elegant with yellow and black spots and stripes. Caterpillars are large, up to 4 cm long, grayish-yellow with characteristic 4-coal spots. The caterpillar hibernates in a cobweb cocoon under bushes in fallen leaves. In the spring, it emerges from the cocoon and damages the buds and young leaves, then pupates, attaching the spider cocoon to the leaves. 2 generations of pests hatch per season

The nature of the damage. Caterpillars eat leaves, digging large holes in them or eating them along the veins. In the spring, buds are severely damaged, which do not bloom, but dry up. If no action is taken, they can eat almost all the leaves on the bush.

How to spray bushes. If you start fighting the moth in time, then you can avoid unpleasant consequences.

1. Spider cocoons are collected and destroyed on and around bushes.
2. Treatment with biological products, Fitoverm, Bitoxibacillin, Lepidocid. Spray currants (and other shrubs where the pest is seen) when the leaves bloom and in early July, when the second generation of caterpillars hatch.
3. With a strong spread, when mild means of control are insufficient, they are sprayed with insecticides: Spark, Karbofos, Biokill.

Folk ways of struggle. If there are a small number of pests, you can deal with them using folk methods.

1. Spraying with infusion of tobacco dust.
2. Spraying with a decoction of tomato tops. 1 kg of tops, fresh or dried, pour 1 liter of water, boil for 30 minutes, insist 2 hours. The resulting concentrate is brought to 10 liters and sprayed with shrubs.
3. Processing with mustard infusion.

Folk methods are used both for control and for prevention. The smell repels butterflies, and the substances contained in the products have a burning effect on the delicate belly of the caterpillars and they die.

rose leaf

This pest is dangerous not only for currants, but also for other plants.

Description of the pest. Polyphagous pest. Damages many horticultural crops, including currants.

Butterflies are medium in size, the front wings are yellow with small brown spots, the hind wings are light brown. Caterpillars are green and brownish-green. The eggs hibernate on the bark under the shield. In the spring, caterpillars emerge from them, which feed for 25-40 days, then pupate. The mass flight of butterflies takes place in June-early July, they lay up to 250 eggs. Over the summer, 1 generation develops.

There are other types of leafworms, all of them, as a rule, are omnivorous and can damage currants.

The nature of the damage. The photo shows how the caterpillars twist the leaf, fastening the edges with cobwebs, they live in it and come out of it to feed on neighboring leaves, buds, flowers and fruits. During the season, the pest changes its shelter several times, twisting new leaves into a tube on a bush. In the same leaf, he pupates.

Wounds of various sizes and depths appear on damaged fruits.

Damaged flowers acquire a reddish tint and fall off without setting fruit.

Ways to fight for all types of leaflets are the same.

1. Collection and burning of rolled leaves.
2. The use of insecticides: Karbofos, Alatar, Iskra, etc.

Measures to combat leafworms should affect all fruit and berry plantations, since it easily moves from one type of shrub to another.

Folk remedies for pest control. As protective measures, agents with a strong odor and contact agents acting on caterpillars are used.

1. Decoction of wormwood. 1/2 bucket of finely chopped fresh wormwood pour 10 liters of water and infuse for 48 hours. Then boil the infusion for 30 minutes, cool, bring the volume to 10 liters and process the trees and shrubs. Instead of fresh wormwood, you can take dry powder 700-800 g.
2. Spraying with tobacco infusion.
3. A decoction of tomato leaves.
4. One of the effective measures for catching butterflies is sugar syrup or fermented currant jam. Banks of 0.7-1 l are filled with bait by 1/3 and hung on bushes at a height of at least 1.1-1.3 m. The next day, banks with trapped butterflies are removed. You can use bread kvass instead of these ingredients.

Prevention.

1. Early spring "blue" spraying of the garden with the addition of insecticides to the solution.
2. Regular inspections of plantings for the presence of various pests.
3. Spraying the garden in spring when the snow melts and in autumn when the air temperature is not higher than 8 ° C, with a concentrated solution of carbamide (700 g / 10 l of water).

gall midges

Description of the pest. Gall midges are small insects, there are 3 types: leaf, shoot and flower. The larvae overwinter under bushes in the soil at shallow depths. During the period of bud protrusion, adult insects fly out - mosquitoes of the flower midge, at the beginning of flowering a leaf midge appears, during the flowering period - shoot midge. Mosquitoes fly in the lower part of the bush and into flowers, lay eggs on leaves and in cracks in the bark. They hatch into yellowish larvae that feed on plant sap.

In the photo is a gall midge caterpillar.

Nature of damage. The larvae suck juice from damaged tissues. Swellings (galls) or wrinkling appear on the affected organs.

Affected flowers do not set. They acquire a reddish color, curl and crumble.

On the shoots, the larvae live under the bark, forming colonies there. Small galls first form on the bark, and then it dies off. Shoots stop growing and dry up.

With the mass spread of the pest, the bushes are strongly oppressed, the branches dry and die, the yield comes to naught. Control measures must be taken immediately, otherwise you can lose landings.

How to deal with a pest.

1. Flowers inhabited by gall midge are very difficult to identify, but the leaves and affected shoots are removed.
2. Treatment with broad-spectrum insecticides. The same solutions are used to water the ground around the currant to prevent the emergence of mosquitoes.

Folk remedies.

1. Cover the soil under the currant bushes during the summer of mosquitoes with newspapers, film, agrofibre.
2. Dusting or spilling the earth under the bushes with ash or infusion of tobacco dust.

Prevention.

1. Preventive spraying of currants with insecticides before flowering and immediately after it.
2. Mulching the soil around the bushes with peat or sawdust.

The most important thing in the fight against gall midge is to recognize it in time. In the initial stages, dealing with it is quite simple.

It should be remembered that when any pest appears after fruit set, the fight against it should be carried out only with biological preparations.

Apple and currant are two unpretentious plants that are in the yard of almost every house. Their fresh fruits can give a person a year's supply of vitamins. For the winter, they prepare all kinds of jams and compotes. Twigs with leaves are used for brewing tea, as well as for canning. However, pests are able to destroy them in a short time.

The most dangerous are two representatives of the arachnid class, the presence of which is noticed too late due to their microscopic size. Having settled on a currant or apple tree, bud and spider mites feed on juice, which can lead to the death of plants.

Characteristic features of pests

Bud and spider mites are pests whose size rarely exceeds 0.5 mm. However, due to their numbers and fertility, they are able to cause enormous damage to the site.

The difference between these arthropods is that the localization of the kidney mite is only currant, mainly its chokeberry varieties, while the spider mite lives on more than 200 plant species.

With the naked eye, signs of the appearance of pests become noticeable when there is already a large colony of them on the plant. The measures taken for the control, as well as their effectiveness for the plant, depend on the time of detection.

In order to timely identify ticks, it is necessary to carefully examine fruit and berry plants several times during the season for the presence of unnaturally swollen buds, or deformed leaves that have changed color.

Representatives of the group of ticks are activated in April-May, when the buds on the plants begin to swell, the first leaves appear. This is the moment when pests are most vulnerable to the effects of drugs.

kidney mite

This pest affects only one type of berry bush, for which it got its name.

The currant bud mite lives in the kidneys, as it does not tolerate high temperatures with dry air. During spring flowering, diseased buds wither, pests from them move on to young shoots. There they settle in the axils of the leaves, starting active reproduction. In one kidney there can be a colony of up to 8 thousand ticks.

The main method of pest control is regular inspection of plants, identification, destruction of affected shoots. You can determine the infection of a shrub by characteristic signs:

• in winter, the buds in which the pests are located look larger than others;
• in spring, mite-affected shoots lag behind in growth, there are few flower brushes, single young leaves are deformed and develop poorly;
• in the summer, diseased bushes lag behind in development, shoots are underdeveloped, there are very few fruits or they are completely absent;
• in autumn, after the leaves fall, the difference in shape and size between diseased and healthy buds is clearly visible.

If there are only a few damaged buds on a shrub, then it is enough to remove the shoot on which they were found. With a strong infection, the plant must be cut off completely. Bushes grown from replacement shoots will not be affected by a bud mite. Sick shoots will never give leaves and a full harvest, so there is no need to feel sorry for them.

spider mite

If the spider mite on the currant is not identified and destroyed in time, it can infect all the plants in the garden. In addition to currants, this pest loves to live on apple trees. It hibernates under fallen leaves, and with the onset of spring, it rises again to the plants.

It is especially active in hot, dry years, settles on the underside of the leaf blade, where it makes punctures, sucking out the juice. Signs of its presence become visible almost immediately, namely:

The spider mite has more than 1200 species, about 100 genera. The most common is considered ordinary. The color of this representative depends on his age:

• the larval stage is always light green or greenish brown;
• in adult females that have overwintered, the color ranges from orange-red to rich red.

The female pest during the season makes 5 clutches, each of which can contain up to a hundred eggs. A week later, larvae appear from the masonry, and after another 1.5-3 weeks, a nymph.

The appearance of white and yellow spots on the leaves of an apple tree or currant is the first signal of their infection. Affected plants become susceptible to any kind of diseases, develop poorly. A large accumulation of pests can lead to crop loss and complete death of fruit trees and shrubs.

Use of chemical and biological treatments

Plant protection against bud and spider mites is complex, including preventive actions, as well as direct destruction of the pest with chemical and organic preparations.

Ticks belong to the class of arachnids. Therefore, they are not affected by means aimed at combating insects, namely:

If a kidney or spider mite is detected on currants, then before you fight it using drugs, you need to cut out especially infected branches and burn them. It is necessary to process not only the affected areas of the plant, but also healthy ones. In addition, the drug is applied to nearby trees with shrubs.

Folk recipes and preventive measures

There are situations when the use of chemical and biological agents is unacceptable. In this case, you can use proven folk processing tools, which include:

It is impossible to get rid of kidney and spider mites without regular prophylaxis. Therefore, to reduce the number of overwintered ticks, it is necessary:

Apple and currant, favorite places for ticks to settle. In order for these plants to be healthy and give a good harvest, proper agrotechnical conditions must be created for them, which can only be met with proper, thorough care of the garden, as well as regular watering.

Like other berry bushes, red, white and black currants are often attacked by pests. Of course, it is necessary to fight them, but carefully, so as not to harm yourself - use chemical agents only before flowering, after - only biological and folk remedies.

Remember that currants from pests are needed in dry weather, preferably in the morning and evening hours, when there is no scorching sun.

Currant pests

Of the most common - spider mite, kidney mite, glass case, berry sawfly, aphids, gooseberry moth, leafworm caterpillars.

Spider mite on currant

This pest lives on the underside of the leaves, weaving a thin web. Damage looks like this: light dots first appear on the leaf, then discolored areas, the leaves become “marbled”, gradually dry out and fall off. The spread of the tick is facilitated by dry hot weather. This pest hibernates under leaf litter and in the upper layers of the soil, so be sure to remove fallen leaves in the fall and loosen the soil under the bushes.

How to treat currants from spider mites, which helps

• spraying with a biopreparation Fitoverm (according to instructions). It is a biological insecticide.
• in the spring, before bud break, spray with preparations: Actellik, Akartan, Zolon, Karbofos (or), Metafox, Phosphamide, Cidal, Karate, etc. (according to the instructions attached to them). In case of mass lesions of the currant by a tick, on the eve of the flowering of the currant, they are re-sprayed with one of the same preparations (it is advisable to alternate).
• in dry weather, it is quite effective to spray currant bushes with water.
• from folk remedies, spraying the bushes with infusion of onion peel is used. 100 g of husk per 5 liters of water, leave for 5 days, strain, spray the bushes.

damage to currant aphids

Aphids on currant

Clusters of aphids are usually located on the underside of the leaf. Most often, the tops of the shoots are affected. The leaves are curled, often in these places you can see ants. Subsequently, the currant leaves affected by aphids dry out and die, so it is better to cut off the twisted leaves and burn them immediately. Aphids hibernate in the egg phase right on the bushes.

Processing from aphids is carried out mainly in the spring.

Fighting aphids on currants in spring

• spraying with Fitoverm biopreparation (according to instructions)
• in spring, before bud break, spraying with insecticides: Actellik, Karbofos, Hostakvik, etc.
• from folk remedies for aphids on currants: 10 g of mustard powder per 1 liter of water, insist for two days, strain, dilute 5 times with water and spray the bushes. Spraying currants with infusions of garlic, tobacco, orange peels is also effective.

currant damage by berry sawfly

berry sawfly

Berries damaged by this pest seem to ripen ahead of time and acquire a slightly ribbed shape. The sawfly pupae overwinter in the upper layers of the soil, right under the currant bushes, so in the fall it is advisable to remove the fallen leaves under the bushes and loosen the soil well.

Measures to combat the berry sawfly

• during the season, regularly destroy infected berries before the sawfly leaves for the winter (mid-July).
• in the spring, before flowering, it is necessary to spray the currants with one of the preparations: Actellik, Karbofos, Etaphos or others of a similar action.

Caterpillars of a biennial leaf roller

They eat out the buds, entangle them with cobwebs and pupate inside. This pest hibernates in cobweb cocoons under fallen leaves or in cracks in the bark. One caterpillar can destroy up to 30 buds.

Processing currants from a leaflet

• in spring (in May, during the mass departure of leafworm butterflies), spray the bushes with insecticides: Actellik, Decis, Zolon, Phosphamide, Chlorophos, etc.

fire on the currant

gooseberry moth

Berries damaged by this pest ripen ahead of time and dry out on the bush, entangled in cobwebs.

Measures to combat moth on currants

• before flowering, spray currants with Lepidocide or at the very beginning of flowering with Fitoverm (less toxic than the first).
• from folk remedies, spraying with infusion of tobacco, wormwood (1 time during the budding period and a second time after 5-7 days).

Loosen the soil under the bushes in autumn.

Glassware

With the defeat of the currant glass, wilting and drying of individual branches is noted. When cutting currant bushes in the spring, look at the cut - the core is empty or brown, which means you have glass caterpillars.

In the spring, damaged branches should be cut off to a healthy part and burned. Cut off old branches near the ground, leaving no stumps, cover large cuts with garden pitch.

The spring treatment of currants is effective with the same preparations as for moth and sawfly.

Bud mite on currant

Branches affected by the bud mite can be seen in autumn and spring. On them, some kidneys are large, rounded, sometimes swollen to the size of peas.

Treatment of currants from kidney mites

• in the spring, during the period of bud break, treat with the Fitoverm biological product (2 g per 1 liter of water)
• in the spring, before the leaves begin to bloom, pinch off and destroy all such swollen buds (they contain a pest)
• before flowering, treat the bushes with sulfur preparations (40-50 g per 10 l of water), a solution of karbofos (75 g per 10 l of water), or a solution of thiodan
• from folk remedies, spraying with infusions of garlic, tobacco, and dandelion is effective.

How to treat currants from pests and diseases

The pests of currants and gooseberries are almost the same, as is the fight against them. Processing is carried out with the same drugs and folk remedies.

Currant bud mite leads to complete depletion of bushes. Currants take pride of place in many gardens, because this culture is relatively unpretentious and able to give the gardener not only tasty vitamin berries, but also healthy leaves and shoots. The aroma of blackcurrant cannot be confused with the smell of other crops, but sometimes the planting of this crop is at risk of dying due to the invasion of pests. The most insidious of them are currant bud and spider mites. Microscopic in size, they destroy the crop and lead to the complete depletion of the bushes.

The extent of the damage

Both bud and spider mites can lead to crop loss, and in the absence of a fight against them, cause the death of blackcurrant plantings. Despite their small size, these pests cause enormous damage to plants due to their numbers. In addition, bushes weakened by their activity become a target for various kinds of diseases and other pests.

In early April, female bud mites begin to actively lay eggs (up to 8000 from one female), which "ripen" within 6-12 days. After this time, young individuals of the bud mite come out and rush to healthy parts of the plants, climbing inside the still unopened buds. They feed on the sap of plants, leading to the drying up of unopened leaves, inflorescences and young shoots. In one year, a kidney tick gives at least 5 generations of offspring.

Spider mite is a pest that causes weakening of the plant

However, the main danger is not only the depletion of the plant. Even if pest control measures are taken in time, the bush can suffer from the terry virus, which can only be eliminated by the complete destruction of the plant.

Spider mite is a pest that causes weakening of the plant. Its activity leads to a deterioration in winter hardiness, due to which blackcurrants can freeze even in a warm winter with a large snow cover. There is no need to talk about productivity at all, since without a supply of certain substances obtained in the process of photosynthesis, flower buds on this crop are not laid.

Description of pests and signs of their appearance

It is far from always that mites are found on blackcurrants within a few days after their settlement in the plantings. This is primarily due to the small size of the pests. For example, a kidney mite has a body length of only 0.2 mm - females, in males the body is even smaller, and a spider mite - from 0.24 to 0.47 mm (males and females, respectively). Without magnifying glasses, detecting them can be extremely problematic, but traces of their activity are visible to the naked eye.

Signs of kidney mite activity

As its name suggests, the currant bud mite only infects the buds of the plant. It is by their appearance that one can detect the presence of a pest in the plantings. During snowmelt, unusually large buds, sometimes severely deformed, are clearly visible on infected plants. The fact is that sexually mature female ticks winter in them, ready for reproduction with the onset of the first fine days.

The state of plantings and, accordingly, the future harvest depend on the time of detection of spider and kidney mites on blackcurrant. That is why it is recommended to inspect the branches annually for the presence of swollen buds and remove them until the first generation of ticks is released. During summer infection, changes in the shape, color and structure of the apical leaf blades become signs of damage by bud mites. They become leathery, slightly deformed and brighten.

Signs of the appearance of a spider mite

It is not for nothing that the spider mite is called the scourge of gardens, because this pest has more than 200 crops that it feeds on throughout the summer. Only female pests survive the winter, hiding under fallen leaves. In spring, they climb plants and lay thousands of translucent eggs on young leaves. A week later, larvae emerge from them, which entangle the leaf blade with cobwebs and feed on its juices.

Bud mite can lead to loss of currant crop

You can notice the activity of spider mites by carefully examining black currants. First, light microscopic dots appear on the leaves of (single) bushes, which later completely cover them. Gradually, such marbling passes to neighboring leaf blades. Sometimes the thinnest cobweb can be found on berry clusters.

How to process currant bushes

All means for combating ticks on blackcurrant are divided into two types:

• chemical;
• organic (folk).

To reduce the number of pests on a single plant, you can selectively cut out infected branches and destroy them in a fire. It is not recommended to leave cut branches even for a short time within the garden, and even more so to throw them on the ground, as pests can get on nearby healthy plants.

Currant bud mite affects only the buds of a plant

Chemicals

An important point: ordinary insecticides do not work on spider and kidney mites, since these pests are not insects! In case of their appearance, it is necessary to use acaricides and insectoacaricides.

The most popular and safe for humans and warm-blooded animals are preparations based on colloidal sulfur and hormonal acaricidal preparations:

• Envidor;
• Nissoran;
• Kontos;
• Forbid 4F.

It is recommended to use them at the time of migration of female spider mites and kidney mites, as well as during the mass breeding of offspring, that is, in the spring, during leaf blooming. For a greater effect, it is important to carry out two treatments with an interval between them of 10-12 days.

In spring, female spider mites climb plants and lay thousands of translucent eggs on young leaves.

After harvesting, you can use more powerful systemic organophosphate acaricides:

• Rogor-S;
• Bi-58;
• Phosphamide.

Young non-fruiting plantings are treated with acaricides containing active ingredients based on dimethoate:

• Dimetrin;
• Accent;
• Danadim;
• Pilarmax.

It is important not to exceed the dosage of drugs and not to try to use more solution than recommended by the instructions for use. It is also recommended to alternate means so that pests do not develop immunity to them.

You can notice the activity of spider mites by carefully examining blackcurrant

Not quite the usual way to free the garden from uninvited microscopic guests is to breed useful insects in it, which in nature consider mites (including kidney and spider mites) as food. These include bed bugs, carnivorous mites, stetorus (ladybug) and lacewings.

Folk remedies

Among the most popular remedies for spider mites and kidney mites are classic infusions from plants that are distinguished by either a strong aroma or an abundance of bitterness in them. So, the following compositions are considered the most effective:

1. Infusion of tobacco or shag.
2. An infusion of dandelion roots and leaves.
3. Infusion of garlic.
4. Decoction of onion peel.
5. A decoction of unripe walnuts.
6. Garlic infusion.

The lack of folk remedies is the need for repeated processing during the entire growing season with an interval of 5-7 days. Advantages - complete safety for people and pets. Moreover, the processing of folk remedies can be carried out even at the time of the ripening of the crop.

A decoction of onion peel is a popular method of dealing with spider and kidney mites.

Varieties resistant to mites

Unfortunately, at the moment there is no currant variety that is resistant to attack by all types of mites, including bud and spider mites. The second, by the way, does not disdain the destruction of the strongest plants, immune to diseases and pests.

Only some varieties of black currant are resistant to bud mites:

In addition to the listed varieties, the blackcurrant Nightingale Night, Belarusian Early and Minx have a relative resistance to bud mites. Redcurrant bud mite infects as often as blackcurrant. Currently, breeders have bred several varieties resistant to this pest.

Prevention measures

It is possible to effectively deal with mites on blackcurrant bushes by many methods, including pickling plantings with chemistry or using folk remedies. However, a much simpler technique is to prevent the infestation of the garden by these pests.

It is necessary to clean the autumn garden from fallen leaves, in which the spider mite most often hibernates

Despite the apparent complexity, you can stop the onset of ticks on blackcurrant by performing a few simple steps:

1. Regular destruction of weeds on the site. Many pests very often wait out the winter on them, and ticks are among them.
2. Cleaning the autumn garden from fallen leaves. In them, the spider mite most often hibernates.
3. Reproduction of blackcurrant by healthy shoots or already rooted seedlings. To avoid the appearance of diseased plants on the site, it is recommended to warm them up in hot water (up to 46 degrees) for no more than 15 minutes before planting.
4. Strengthening the resistance (own immunity) of plants to pests by timely application of fertilizers to the soil and foliar fertilizing.

In addition, it is important to annually dig up the soil directly under the currant bushes, and in the fall to remove non-fallen leaves and enlarged buds from the plants.

The main point in the fight against spider and kidney mites is timeliness and consistency. With the proper approach and responsible fulfillment of agrotechnical requirements, the bushes of this crop will remain healthy, even if ticks spoil all the plantings in the neighbors' plots.

Spider mite on currants: how to fight and get rid of quickly

But that's not all. In addition, currants can be attacked by barbels, goldfish, stem glass. It is imperative to fight the spider mite as soon as you notice its presence on the bush. But first you need to understand by what signs this pest can be detected, and what consequences inaction is fraught with.

How to identify an infection

The invasion of pests on currant bushes becomes much more active in the spring, when females lay eggs. To diagnose an infection in time, pay attention to the following points:

As soon as you notice a cobweb or yellow dots on a leaf plate, immediately start pest control, otherwise the plant may simply die.

Consequences for currants

How to get rid of spider mites - gardeners often ask this question. The main thing is to start treating the shrub immediately after you notice the presence of pests. Processing the plant will be much more effective if carried out in the spring. In summer, insects multiply very quickly, so it will not be so easy to remove them from currants.

In any case, the choice of effective means should depend not only on the time of year, but also on the degree of infection of the shrub. For example, if you find cobwebs and yellow dots on the leaves of one plant, start by cutting off the affected shoots. In no case do not leave cut branches on the ground near the bush: insects can “migrate” to another healthy plant. It is better to simply burn these sections.

If the situation with the infection of currant bushes is aggravated, it's time to choose the best way to fight:

• folk remedies;
• chemicals.

If a spider mite wound up on a currant, how to deal with it? As an alternative means, you can apply folk methods. These mainly include herbal infusions with a sharp aroma (garlic infusion or onion peel decoction). These tools show a good result, but they have one significant drawback: the processing will have to be done often, during the entire growing season.

Prevention

In order to prevent the appearance of spider mites on currants in the autumn, dig up the soil around the bushes: in this way, you will eliminate female insects that overwinter in the soil near the plant. Fallen leaves should be removed in the fall. Sometimes domestic gardeners can resort to the help of auxiliary plants.

If you plant calendula near currants, its pungent smell will repel pests. Reduce the risk of bud mite invasion and timely pruning of shrubs. Take care of black or red currant bushes in advance - and you will be able to avoid pest problems once and for all.

The pest infects grapes quite often. Spider mite on grapes - how to fight? Methods for combating this pest include a set of chemical and agrotechnical measures:

For raspberries, this pest is especially dangerous - during the drought period, crop losses can be up to 70%.

There are several ways to deal with spider mites on raspberries:

1. Careful removal of weeds and fallen leaves - female ticks hibernate on them.
2. Spraying the bushes with a solution of urea. This method is more likely to prevent infection. This should be done in the spring, before the buds begin to bloom.
3. Treatment of raspberry bushes with Fufanon. It is used for severe damage to the bush.
4. Treatment with Akrex or Actellik. Produced after picking berries. If the infestation is severe, two sprays may be needed. In this regard, Akrex is stronger than Actellik.

On currant

Spider mite on currant - how to fight? You can get rid of the pest on currant bushes in the following ways:

1. In the spring, when the buds open, they are sprayed with acaricides - Antio, Metaphos, Akartan, Zolon, Vofatox, Phosphamide, colloidal sulfur or any other.
2. On the eve of currant flowering, if the damage to the bushes is severe, re-spraying should be done.
3. It is necessary to clear the space around the bush from fallen leaves and weeds, and also to dig the soil from time to time - this helps to reduce the population of spider mites.
4. Spraying with infusion of onion peel every 5-7 days.

It should be remembered that the use of one drug forms immunity in ticks to it, so they need to be alternated.

On a lemon

The lemon tree is most commonly affected by the red spider mite. It feeds on the juice of young leaves and is quite difficult to detect at first. Spider mite on lemon - measures to combat it:

1. Spraying the tree with sulfur.
2. Spraying with acaricides. Used on an industrial scale. If a lemon grows at home, it is better not to process it with chemicals.
3. Treatment of leaves with soapy water. At the same time, each sheet is wiped with a sponge dipped in a solution. Particular attention should be paid to the underside of the sheet. To prepare the solution, it is best to use natural laundry soap.
4. Treatment of leaves with an alcohol solution. For this, ordinary medical 96% alcohol is suitable. Before processing, be sure to remove all damaged parts of the plant. A week later, the procedure is repeated.
5. Treatment with 35% Sulfarid paste.
6. Tick ​​control with ultraviolet light. This pest does not tolerate ultraviolet radiation (therefore, it is located mainly on the underside of the sheet). In order to destroy it, the tree is placed under a special lamp for one and a half to two minutes.

This method can be used as a preventive measure - after such a session, the lemon becomes more resistant to any pests.

How to deal with spider mites on currant0 min read

The value of currants - red, black and white - surpasses other berries in many healing indicators, therefore, a spider mite that appears on currants, which destroys foliage on bushes, can threaten with crop loss.

Measures to combat the malicious tick horde that has occupied berry bushes depend on many factors.

The first and important factor is the time when there was a significant infection of the currant with a spider mite.

• If the tick manifested itself massively before the ovary ended, and even more so before flowering, then it is necessary to fight the tick colony with all your might - under the threat of ripening berries.
• If the berries have already managed to start and are quietly ripening under the sun, then the tick will not bring tangible harm to the crop, but it will spoil the foliage. But this does not apply to bushes covered with colonies of a spider web pest - then special measures will be needed.

• If there are few spider mites on currant bushes - and the number of modified diseased leaves will tell about this, then physical measures will do just fine to get rid of the berry pest.
• When the bush has suffered significantly, you will have to resort to “killer” drugs to fight, and this will not depend on the ripening of the berries.

Over the years, gardeners have figured out how to reliably get rid of the spider mite on the currant, using labor efforts, improvised measures, other plants and even insects - the natural enemies of the spider mite. Here is the best experience in the fight against berry pests, including spraying with mite-killing acaricides.

What threatens the currant spider mite

Spider mite on currant

• The dotted “bloodless” leaf acquires a marble pattern of white spots, which then darken.
• The foliage, suffering from a lack of nutrition, twists and falls, and the mite colonies move to other parts of the plant - stems, flowers, fruits, entangling parts of the currant bush with their cobwebs.
• In the dry summer heat, spider mites multiply rapidly - in 3 days hundreds of eggs turn into juice-hungry larvae, and a week later they themselves make clutches. Therefore, at the height of summer, it is already difficult to deal with tick families swarming on the bush.
• The life of a spider mite is short - it does not exceed 24 days, but the female will leave hundreds of eggs during this time.

How to get rid of spider mites before flowering currants

Before the flowering of the currant bush, if a spider mite is found on it in quantities that threaten the berry, control measures can safely include preparations with an acaricidal effect. But only if other methods were unsuccessful.

Therefore, to remove the spider mite on blackcurrant, the control measures are not very different from the measures for red or white.

• Abundant watering of a currant bush, on which a colony of ticks has settled, with an intense jet of water can simply wash off most of the tiny insects.
• You can spray a bush, and immediately wrap it up for a short time with a film, creating inside a deadly humidity for a tick - it dies at 80%.
• The web that entangles the berry bush must be collected, otherwise it will turn into a barrier to liquid, and the efforts of the struggle will go down the drain.
• It is important to carefully pluck each leaf damaged by the spider mite beforehand, and then burn it so that the pests do not remain to winter in the soil of the garden.
• It is possible to furnish a currant bush with open jars with turpentine or ammonia poured into them and, for a while, cover it with a film in the same way - such measures will quickly kill a malicious family.
• At first, you can try decoctions or infusions that have acaricidal properties given to them by nature - spraying with such a liquid is sometimes as effective as chemistry when there are not too many ticks on the foliage.
• When the damage to the currant is significant, it will not work without acaricidal preparations - all efforts will have a zero result.

But even chemistry is not omnipotent - the spider family, due to the rapid change of generations, soon gets used to poisons and becomes less susceptible to those.

How to expel a spider web pest when the currant is already ripe

If the ovary on the currant occurred successfully and on time, and the traces of spider mites are single, then there is no point in radically fighting the pest at this stage - it is enough to stop the further growth of the population.

Important! When such remedies do not stop the tick horde from further damage, then one can resort to biological preparations - the use of chemical poisons on ripening currants is undesirable.

What is the best way to get spider mites out of the garden

Safe means for currant berries in the summer will be infusions and decoctions of plants, or biological products. But when there is a threat to neighboring bushes, and all methods have given a zero result, then the turn of “lethal” chemistry comes.

Plants to combat spider mites on currants

Decoctions of some fresh or dried herbs, as well as their infusions, have a weak acaricidal property, but the active substances that work against spider mites in them do not have resistance. Therefore, the treatment will give an effect only in the evening or morning, when the sun does not fry.

• Wormwood, dope, dandelion, yarrow, calendula, and celandine cope well with pest colonies.
• No weaker than their garlic and onions, the gruel of which, when diluted with water and daily infusion, will destroy most of the spiders.
• Many have tried the infusion of potato tops and got a poisoning mite result.

Currants will have to be sprayed every 3 days - eggs are resistant to these liquids, so newborn generations will also need to be processed.

Biological products against spider mites on currants

Achievements in biochemistry - insecticides and acaricides based on biological weapons, which are microorganisms, are replacing the usual harmful chemistry because of their perfect safety.

• Only those insects that feed on processed greens will receive a natural substance inside that inhibits their life processes, which will eventually lead to death.
• Instant death of the tick family will not happen - the agony will last up to 12 hours, and then it will only affect adult ticks and larvae, the eggs will survive.
• Therefore, a cycle of 3 - 4 treatments is required, and the interval will depend on the weather. At t up to 30ºС it is equal to 5 - 6 days, at t above 30ºС - no more than 3 days.

On currants affected by spider mites, the following preparations showed an impressive result:

• "Vertimek",
• "Fitoverm",
• "Aktofit",
• "Agravertin",
• "Kleschevit".

Note! There is no harm from processing them either for berries, or for people, or for the soil, or for beneficial insects.

Chemical acaricides against spider mites

Treatment with powerful pesticides is possible only before flowering, later there is a risk of poisonous substances getting into the pulp of the berries - instead of benefit, you can get poisoned.

The only time when the treatment of currants with a chemical poison is justified is when we are already talking about a crop from a bush infected with a mite, but the surrounding plants are under threat, and they already need to be saved.

The solution for acaricidal treatment is prepared in accordance with the instructions, and all stages of spraying are carried out according to it.

The spider mite, as mentioned above, will not die out from any chemistry, so it is quite possible that you will have to change the remedy to a similar one, but with other poisons at the base.

Tick ​​eggs are also invulnerable to acaricides, therefore, according to the instructions, 3 stages of processing are implied.

Traditionally, currants are saved by such drugs:

• "Floromite",
• "Sunmite"
• "Oberon"
• Flumite,
• "Apollo"
• "Nisoran".

Important! Keep the package where the poison is indicated in the basis of the drug - in case of an unsuccessful outcome, buy a remedy with a different base!

Biological enemies against spider mites

You can resort to their natural enemies to save the berries from the spider web pest. These are predatory mites that feed on their brethren - amblyseius and phytoseiulus, which are sold both on the Internet and in gardening and floriculture salons.

This remedy is the simplest in terms of effort and quite expensive in terms of finances - the packaging of mites is designed for an average houseplant, so several of them will be required for a currant bush.

But you can forget about the hassle of destroying ticks - predatory relatives will now gladly take on this task until they exterminate all the web "brotherhood".

Prevention against spider mites in the garden

Some gardening work can prevent the appearance of such a misfortune as a spider mite on green pets.

Important! All parts of the plant with traces of spider mites must be burned, and not buried in the soil!

Currants take pride of place in many gardens, because this culture is distinguished by its relative unpretentiousness and the ability to give the gardener not only tasty vitamin berries, but also leaves and shoots that are healthy for health. The aroma of blackcurrant cannot be confused with the smell of other crops, but sometimes the planting of this crop is at risk of dying due to the invasion of pests. The most insidious of them are currant bud and spider mites. Microscopic in size, they destroy the crop and lead to the complete depletion of the bushes.

The extent of the damage

Both bud and spider mites can lead to crop loss, and in the absence of a fight against them, cause the death of blackcurrant plantings. Despite their small size, these pests cause enormous damage to plants due to their numbers. In addition, bushes weakened by their activity become a target for various kinds of diseases and other pests.
