Greetings to garden lovers! This article will talk about currant pests. We will tell you what each pest is, how much damage it can cause to your currant bush and how to deal with it.

Did you know? Juice black currant used to prepare food coloring.

Aphids on currants

Many gardeners have encountered these pests and know about them first-hand. They may not be immediately noticed, since they are very small, which cannot be said about the damage they cause to currants.

Aphids are a superfamily of insects that feed on plant sap and can transmit viral plant diseases.

In addition to the damage that the aphid itself causes, it also attracts other insects to the plant(during the process of life, honeydew is released - a sweet solution). Thus, if you do not get rid of aphids in time, then other pests may “visit” your currants.

In addition to the “ordinary” aphids, there are several species that attack currants:

- gall aphid;

It appears as red swellings on currant leaves (“treatment” is similar to a simple aphid).

-shoot aphid;

Wraps a young shoot at the top of a currant.

The best option would be to tear off these tops and burn them (if you leave them in the garden, the aphids will return to the bush).

Important! Do not forget that ants breed aphids and use them as a source of nutrients. They also spread aphids to other plants, so when dealing with aphids, take care of the ants as well.

You have aphids on your currants and you don’t know how to treat them? Now we will look at possible options that will help you get rid of this problem.

1. Infusion of onion skins. Proportion: 200 g of husk per 10 liters of water. You need to insist for 5 days.
2. Dandelion infusion. We take 0.4 kg of leaves and 200 g of the plant itself with roots per 10 liters warm water. We insist for 2 hours.
3. Infusion of celandine. 1 kg of dry grass per 10 liters of water. They insist for one day.

If you don't want to use old-fashioned methods, you can use organic insecticides. IN in this case a remedy that affects nervous system aphids and kills them - Py Spray Garden Insect Killer or Doff All in One Bug Spray.

The most biologically useful option for killing aphids is moving into your garden ladybugs, which destroy aphids in colonies. To place the “suns” in your garden or vegetable garden, just order their larvae and, following the instructions, propagate them in your garden.

Processing in spring. There is no need to treat currants against aphids with anything special in the spring. You should cut off dried and diseased branches, in which the pest can overwinter, collect leaves and burn This is all outside the garden/vegetable garden. An option for getting rid of the pest may be Sprinkling the soil near the bush with ash and, of course, digging.

Did you know? The best soil for currant growth is chernozem loam, but it can grow on other soils, both light and dense. The soil should be sufficiently moist, so in summer the currants are topped up with liquid fertilizers.

Mite on currants

One of the common currant pests is kidney mite.

– This is a microscopic mite that infects gooseberries and currants. It settles in the buds of the plant, which for this reason acquire a more rounded shape.

Let's look at why it is so terrible for a tree step by step. Firstly, such buds produce weak and deformed shoots that bear almost no fruit. Secondly, the bud mite carries viral diseases of currants (doubleness and mosaic).

Important! If the currant is affected by terry or mosaic, then this bush cannot be treated and must only be uprooted.

This mite lays eggs in the buds in early spring, when the currants wake up and begin rapid growth. When the larvae become crowded in one bud, they infect other buds on the tree. The maximum pest population is observed at the end of currant flowering. After this, their activity decreases.

Important! Do not allow preparations based on colloidal sulfur to come into contact with gooseberries, as they may get burned.

If none of the options suits you, you can find currant varieties that are resistant to bud mite damage: In memory of Potapenko, Sevchanka, Nightingale Night, Belarusian Sweet, Leningrad Sweet, Riddle, Kipiana, Leningrad Giant, Nara, Oryol Serenade, Otradnaya, Chernysh, Black Pearl.

Shields

– a family of hemiptera insects whose body is covered with a dense shield. They feed on the sap of the plant and lead to its weakening.

Currants are affected by a variety called "Willow scale insect." It is distinguished by the characteristic white color of the shield and from a distance can resemble small cocoons or cobwebs. The female lays several clusters of pinkish-colored larvae at the end of June.

The problem is that only the “young” scale insects are susceptible to chemicals. An adult specimen can only be removed from a tree mechanically - by scraping it by hand.

To get rid of young growth, in early spring the bush is treated with Nitrafen 3% (300 g per 10 liters of water).

Important! The drug is dangerous for animals and humans, so do not allow the chemical to get into food and water.

Traditional methods can also help you in removing the pest, namely: infusions of onion, dandelion and celandine, which were described in detail in the first paragraph of the article.

Currant gall midges

There are larvae flower gall midge(appears during the creation of buds), leaf gall midge(appears at the beginning of flowering) and shoot- during the mass flowering of currants.

In the spring, gall midge lays eggs on currant leaves (at the ends of growing shoots).

These same larvae disrupt the leaf structure of the young shoot at the tops of the bush, after which the leaf gradually curls up and dries out.

After the onset of cold weather, the larvae go to winter in the soil.

Important! The reproduction of gall midges is favored by severe pruning of bushes, since this results in the formation of many basal shoots.

How to deal with this pest?

In spring you can spray currant bushes with insecticides, which do their job well. This list includes: Aktellik, Karbofos, Rovikurt and others.

In summer, you need to fight gall midges as follows: cut out damaged shoots without stump(so that the insect cannot colonize new larvae there).

Since gall midge larvae overwinter in the ground, the soil around the bush needs to be dug up in the fall.

Fire butterfly

Ognevka– a family of butterflies from the Lepidoptera division. The butterflies themselves do not pose any threat to plants, unlike the larvae.

After mating, the butterflies lay eggs in the flower. After the ovary and hatching of the larvae, they penetrate deep into the berries, eat away the seeds and pulp.

One such caterpillar can destroy up to 10 currants. You can imagine the damage 10-20 of these caterpillars will cause.

Damage to the moth can be determined by rotten berries and noticeable cobwebs that will cover the currant fruits. The caterpillars finish their long “lunch” in early July, descend to the ground under the bush and burrow 3-4 centimeters into the ground.

Fighting fire floats out of her life cycle.

1. Collect and destroy affected berries and leaves during ripening.
2. In the fall, after the leaves have fallen, dig up the soil and turn over the layer. Hill up the bushes with soil from the row spacing to a height of 10 cm (since the moth overwinters in the ground, after waking up it will not have enough strength to get out from under the 10 cm layer of soil, and it will simply die).
3. Spraying insecticide. For this they use Karbofos(5 g per 20 liters of water).

Important! The insecticide Karbofos is toxic to humans, but loses this property after heat treatment.

If there is a large-scale sawfly infestation, the currant bush may remain completely “naked”, and you will not get a harvest (if the bush is young, then it may dry out completely).

Closer to autumn, sawfly caterpillars descend into the ground (3-4 cm) and enter the pupal stage. After wintering, the insect emerges from the pupa and the cycle repeats.

Fighting a sawfly is similar to fighting a moth:

1. Digging up the soil around the bush. In this case, you will either dig the pupae to a depth from which they will not emerge in the spring, or leave them on the surface where they will freeze.
2. Manual collection of caterpillars from affected leaves. In case of severe damage, you can cut off the currant shoots. It is important that not a single caterpillar remains on the bush.
3. They use decoctions of wormwood, garlic and tobacco, which are sprayed on the bushes during the period of infestation by the caterpillar.

Important! Before using insecticides, carefully study their effect on other plants in the garden, animals and people!

Currant glass

– a pest butterfly that looks like a wasp. There are about 1 thousand types of glass.

She has a small, thick body with vertical stripes. This individual of lepidopteran insects most often harms black, red currants and gooseberries.

How can you understand that it was the currant glass that spoiled your beautiful berry?

Let's start with the fact that the damage caused by this insect is very significant. Damaged currant branches begin to dry out both at the end of flowering and at the beginning of the formation of the berries themselves. In case of massive damage, the currant bush may die.

In order to identify the pest, you just have to look at the branches. If they are dry and have indentations in the middle, as in the photo, which means it’s worth starting the fight against pests of currants and gooseberries.

It is very difficult to fight these insects. This is due to the fact that they spend almost half of their life inside branches.

When you buy currant bushes, you should carefully inspect them so that there are no overwintering glassworm caterpillars inside.

The insect often settles in old currant bushes, so it is worth trimming semi-dry branches as often as possible.

After flowering, currant bushes should be treated chemicals, such as “Fufanona-nova”, “Kemifos” or “Kinmiks”. After all, it is precisely at this time that glass beetles most often begin to infect the plant.

If you do not want to use chemicals, we recommend using biological preparations – “Lepidocid”, “Bitoxibacillin”, “Fitoverm”. These drugs are safer for humans and nature, have high effectiveness and are easy to use.

This is all you need to know about treating currants and gooseberries against such a pest as currant glass.

Currant narrow-bodied borer– This is an insect that looks like a beetle with a metallic greenish sheen. The length of the borer is from six to nine millimeters.

How to determine what kind of borer is destroying your garden?

The currant berries will gradually begin to crumble. At the cut of the branches, small passages will be visible that are filled with a wormhole. They can be identified in the spring, during the flowering period.

If damaged shoots are detected, the best option will cut them off and burn them. It is worth doing this in the fall or spring. A week or two after the start of flowering, treat the bushes with insecticides. Treatment should also be carried out after harvesting.

At the end of February, spend spring treatment of currant bushes from pests. It is best to process currants before the fruit ripens. The soil under the bush is sprinkled with ash, which will save you from the larvae overwintering in the ground.

When purchasing bushes, carefully inspect the seedlings, because they may be sold with pest larvae.

Use chemicals if necessary. Actellik solution is best suited. It is worth treating the bushes three weeks after the end of flowering.

The danger for currants is precisely moth caterpillars, not adult insects.They damage the kidneys and harm their normal development. Affected buds lag behind in development, yields drop, and in winter the bushes weaken and do not tolerate frost well.

Most often, caterpillars overwinter at the base of the bush and crevices in the bark. In early April, adult caterpillars crawl to the tops of the buds, and already in mid-May they descend into the ground to enter the pupal phase.

In early June, the pupae become adult butterflies, which lay eggs in still green fruits. The larvae feed on the seeds of unripe currants or gooseberries.

How to deal with such currant pests?

It is best to exercise caution and carry out preventive maintenance on currant or gooseberry bushes. To do this you need to do the following:

1. Clear the bushes of dry shoots. In this way, you will get rid of currant moth larvae, as you will reduce the amount of space for wintering.
2. Digging up stumps. This will help you get rid of pests inside the soil and renew the planting site for new seedlings.
3. Thinning of plantings.
4. Purchasing new bushes or seedlings.

If it was not possible to protect currants or gooseberries from pest larvae, then you need to start fighting them. Heavily infected bushes should be treat at the end of March with Chlorophos or Nitrafen. Thank you for your opinion!

The appearance of insect pests can reduce the volume of fruiting of even the most productive currant varieties planted in a carefully treated area. Due to the activity of such insects, a garden crop may completely die. To prevent loss of yield and planting material, preventive and therapeutic measures against insect pests should be observed.

The most common pests

Ognevka

The most common one, the gooseberry moth, is a representative of the biological order Butterfly. It has small dimensions and gray wings. The location of the pupae of wintering moths is in the soil, under bush currant plantations, which complicates the process of controlling moths on currant bushes. Their appearance occurs in the spring when the air temperature is stable and warms up to +13°C. The cavities of currant bush flowers serve as a reservoir for the ovipositor. The number of moth individuals on one bush can reach two hundred. Caterpillars appear a week after laying eggs. You need to know what the currant moth cannot tolerate and how to deal with its appearance, otherwise its constant presence in the garden will lead to the death of the currant planting. Timely measures taken to combat the gooseberry moth will allow you to preserve the ripe crop.

Damage to gooseberry moth

Important! The moth caterpillar is one of the most active fruit eaters. One insect does this instantly, eating 15 pieces of a ripening currant crop at a time.

Gallica

Gall midges are a type of small flying insects similar to mosquitoes. The affected area where the gall midge has settled on currants can be any part of the plant. Adults are 2 mm long and have a yellow-brown color. Initially white, as they develop the color of the caterpillars changes to red-orange, and at the last stage of growth it turns into red.

Swollen galls

There are three varieties of gall midge:

• Leafy ones that damage young leaves by eating and settling on them. A leaf damaged by leaf gall midges does not develop, curls and falls off. Young shrubby shoots are most susceptible to leaf gall midge invasions;
• Flower gall midges lay eggs in the ovaries of flowers, which leads to the death of the inflorescences, which acquire a spherical shape. Saturated larvae move from the bud to the soil;
• Stem gall midges select cracked fragments of the trunk of currant bushes for ovipositor. This happens at the end of the flowering stage. For nesting, the larvae choose a place under the bark, where huge colonies are formed. Fragments of bark inhabited by stem gall midges, as well as shoots, die.

Important! Large-scale damage by stem gall midges will lead to the loss of more than 70% of garden plantings, not only currants, but also gooseberries.

While in the larval stage, each of the above representatives of the gall midge species overwinters in the upper layer of soil. Pupation of caterpillars begins with the onset of stable warming. With the transition of the bush to the flowering stage, mature individuals are activated.

Weevil

All weevils are divided into two types:

1. short-proboscis;
2. long-proboscis.

leaf roller

The leaf roller is a 3-centimeter moth whose wings fold exactly horizontally. The larvae are yellow-green in color. The number of eggs laid at a time is about a hundred. The caterpillars are distinguished by a black head with rows of peculiar hooks on the sides of the body, which is devoid of hair. In addition to destroying leaves, leaf rollers also eat buds. The overwintering place for the currant leaf roller is leaves shrouded in cobwebs.

1. Boil a kilogram of dried wormwood with a small amount of water for 15 minutes. The wormwood solution is diluted with 10 liters of water;
2. Finely chop 1 kilogram of tomato tops and place in 11 liters of water. After boiling for half an hour, add 40 grams of laundry soap;
3. Pour 100 grams of finely chopped hot pepper pods into a liter jar of water. After boiling for an hour, leave for two days. Filter, dilute with water in the ratio of half a glass to 10 liters of water and add 40 grams of laundry soap to the product.

The drug Fitosporin

Note. It is permissible to process the currant bush in winter time, but provided that the leaves completely fall off at the very end of autumn, before the onset of the first cold weather.

Gall midge is an insect pest. Find out what the gall midge looks like, why it is dangerous, how it reproduces, and more. Detailed description leaf currant gall midges as an insect pest. Preparations have been selected to destroy gall midges.

What does currant leaf gall midge look like?

The currant gall midge is a tiny brownish-yellow dipterous insect less than 2 mm long. Harmful to black currants; most dangerous in nurseries. It has become widespread in the European part of the Russian Federation.

How is the currant gall midge harmful?

The larvae wait out the winter in white cocoons in the top layer of soil under currant bushes. Pupation occurs in the spring. The emergence of adult gall midges usually coincides with the phase of exposure of buds and the beginning of currant flowering. Eggs are laid in the folds of the budding upper leaves. Fertility averages 50 eggs. After 3 - 4 days, legless translucent larvae appear. Their feeding causes distortion and drying of young leaves. At serious damage the growth of the shoot stops, its top begins to dry. Larvae that have finished developing begin to pupate in the soil. From 3 to 4 generations develop per year.

Methods of combating gall midges. How to destroy gall midge?

It is necessary to plant industrial plantings with exclusively healthy planting material. Be sure to carry out autumn or early spring digging, loosening and mulching of the soil, and remove damaged shoots. If more than 10% of the bushes are populated during the budding period, then you need to use bitoxibacillin, kemifos, fufanon, actellik. Spraying can be repeated, if necessary, during the formation of ovaries, as well as after harvesting. Nurseries also use BI-58 New, karate.

Currant gall midges are small flying mosquito-like insects that can infect all parts of the plant. In the places where their larvae feed, peculiar swellings are formed, called galls in gardening. They mainly affect blackcurrant bushes. There are three types of gall midge on currants:

1. Leafy;
2. Floral;
3. Stem.

Mature mosquitoes have a yellow-brown color, and their body length reaches up to 5 mm. Komakh caterpillars first have White color, and as they develop they acquire a red-orange hue, becoming scarlet at the end. All varieties overwinter on surface layer soil in the larval stage. With the onset of warmth, they pupate, and at the first flowering of the bush, adult individuals begin to activate.

Leaf gall midge on currants

Taking a closer look at currant leaves in summer, you can sometimes see next picture: Just yesterday, the juicy green leaves of the bushes began to swell at the bottom, and red and brown spots appear. This is the currant gall midge. This is the name given to the gall aphid, a well-known garden pest that can destroy beautiful foliage in a short period of time. In summer, winged individuals appear in aphid colonies, which migrate to herbaceous plants from the Lamiaceae family, where they feed and reproduce until the end of summer. Wingless individuals feed on currants until September. The spread of currant gall midge is promoted by warm winter and dry summers.

Flower gall midge on currants

Stem gall midge on currants

Stem gall midge pests lay eggs in a crack in the blackcurrant trunk after the flowering phase. Their larvae nest comfortably and actively under the bark, gathering there in large colonies. In their habitat, the bark of the bush dies, which leads to the death of the shoots. Widespread distribution of currant gall midge in the garden can lead to significant loss of plantings.

Interesting to know! The most complete scientific taxonomy describes 780 genera and nearly 6,000 species of insects with common name gall midges.

Symptoms of infection

The pest larvae of gall midges feed on currant juice from young leaves. As it is sucked out, thickenings begin to appear on it, the leaf becomes covered with red spots, begins to curl, and dry out. As soon as the growth of shoots stops and the leaves begin to coarse, they no longer become attractive to the currant gall midge. As the larvae develop, they transform into winged insects and are already able to fly to other plants in the garden.
The flowers of currant bushes also curl and fall off, resulting in a sharp reduction in yield.

Measures to combat gall midge

It is necessary to begin the fight against Currant Gall midge in the fall. Carefully inspect the bushes for damage to the bark. Trim all branches and burn them immediately. Spray the bushes with 0.2% DDVF or 0.3% karbofos. Remove all weeds from under the bushes and fluff up the soil. Treat it with Bordeaux water and apply natural fertilizer.

In the spring, immediately after the snow melts, amateur gardeners recommend treating currant bushes with boiling water. To do this, you need to boil water, tie the branches of the bushes into a bundle and treat them with boiling water. Don't forget about safety precautions.

A week later, even before the buds open, spray the black currant bushes with nitrafen.
If the currant gall midge strongly attacks your bush, then you will have to treat the bushes with Tsvetofos or 30% Karbofos.

Preventive measures

In order to prevent currant gall midge, it is recommended to thin out the rows of bushes more often. Avoid dense plantings and systematically treat the soil with tobacco water. Remember that it overwinters in the top layer of soil. great amount currant pest larvae.

Every three years, rejuvenate the bushes. To do this, after harvesting, you need to cut off old and damaged branches.

It is very important to use healthy planting material when planting.

Folk methods of combating currant gall midge

Traditional methods successfully fight all pests in the garden. That is why they are also called preventive. From folk remedies The fight includes digging and loosening the soil, as well as the practice of collecting and burning branches and foliage damaged by gall midges. Place peat mulch under the bushes.

And if gall midge appears on currants during the growing season, then the treatment should be carried out with one of the following infusions:

• potato tops;
• infusion of marigolds;
• calendula;
• Luke;
• soap suds.

Interesting fact! When processing blackcurrant bushes, you need to remember that in addition to chemical and traditional methods struggle and gardeners have their own assistants to combat gall midges - beetles and larvae of ladybirds, lacewings, larvae of hoverflies that feed on them and destroy them in large quantities. A bunch of beneficial insects can be found in the garden in the second half of summer. Therefore, the fight against gall midges must begin in spring and continue until mid-summer. And in order to attract their helpers, gardeners recommend sowing nectar-bearing plants in the garden.
