Currant glass jar and narrow-bodied goldfish - how to deal with them

Intra-stem pests of currants and gooseberries

The currant is not spared by numerous garden insects - pests, among which currant goldfish and glassworm are among the most harmful and difficult to eradicate, since their caterpillars live inside the branches in the bushes.

Currant glass

Glass currant is a widespread butterfly, which is considered a serious pest of both currants of all types and gooseberries. In the spring, after budding, the branches on the bushes of these berry crops that have dried up among the green foliage draw attention to themselves. If such a branch is cut with a pruner, then a dark hole with blackened walls stands out sharply in the center of the cut - a cavity forms instead of the core.

With a longitudinal section of the stem, you can sometimes find a pink caterpillar 20-30 mm long with a brown head and eight pairs of legs. According to experts, in the middle lane, it damages 10-50% of the branches of perennial plantings of black currant, on the bushes of white and red currants, the damage reaches 10-30%.

The small currant glass butterfly (22-25 mm in wingspan) has a bluish-black body with glassy-transparent wings bordered by an orange stripe; black veins are also clearly distinguished on them. On the abdomen of the female there are three light yellow transverse stripes, in the male there are four of them, and the abdomen itself ends with a bundle of blue-black hairs.

Butterflies usually start flying one and a half to two weeks after black currant bloom, they are active on warm sunny days. Exit from pupae and their years will stretch (about 5-8 weeks), but ends, as a rule, by the ripening period of berries. For a short time of her life (5-7 days), the female lays up to 60 eggs, placing them near cracks or mechanical damage on the bark of branches of the zero and first orders of branching, or near the buds at a height of 40-70 cm. Clutch is single, eggs are slightly oval , light brown with a mesh-like pattern on the surface. This drawing can only be clearly seen with a magnifying glass.

Egg development continues for 10-20 days, depending on weather conditions. After hatching, the caterpillar bites into the core of the branches (it is able to penetrate through the cut, bud, petiole fossa, crack, wound), where it feeds, making there smooth passages with black walls (up to 30-50 cm long). During its development, it damages several branches, passing from thin stems to thicker ones.

Depending on weather conditions, the life cycle of the pest can last 1-2 years. After feeding, caterpillars (usually II and III instars) hibernate. After wintering, they continue to feed. Some of the caterpillars pupate in May, having previously prepared the external holes for the departure of butterflies, but most of them, gradually descending to the base of the branches, remain to winter inside the branches a second time. In early summer, the caterpillars make a flight hole in the wood, leaving the bark film intact, and pupate. Mass pupation of caterpillars, as a rule, coincides with the period of mass flowering of black currant.

It takes 3-4 weeks for the pupa to develop, then butterflies emerge from them. On the branches damaged in the first year, at first outwardly not very different from healthy ones, the leaves and fruits become smaller. Signs of wilting and drying of damaged branches, as experts note, are noted at the end of flowering or at the beginning of berry formation, when older caterpillars feed. Such damaged branches, as noted above, are especially prominent during the leaf blooming next spring.

Control measures

It is extremely difficult to fight this dangerous pest, since it spends almost its entire life inside the branches. First of all, when purchasing planting material for currants and gooseberries, it is necessary to carefully examine. This allows you to discard plants with caterpillars of this pest wintering there and avoid bringing them to your site. It must be borne in mind that with the aging of the bushes, the number of this pest increases, therefore, it is necessary to fight it, reducing the population, annually. Experts believe that the most convenient moment for the fight is only a short period of summer of butterflies and their laying of eggs, but it is not quite easy to catch it. Some amateur gardeners determine the beginning of the departure of butterflies by placing containers with fermented and diluted blackcurrant jam next to the bushes.

Of the chemical preparations for the fight, spraying of gooseberry and currant bushes after flowering with a 0.1% solution of fufanon, Kemifos, Iskra M or a 2.5% solution of kinmix is ​​used. This period coincides with the summer time of the butterflies. For each bush, 1-1.5 liters of working fluid are consumed. Biological preparations can be used: lepidocid (20-30 g / 10 l of water), bitoxibacillin (80-100 g / 10 l) or fitoverm (2 ml / l) at a working solution consumption of 1-1.5 l per bush. Here it is necessary to guess the time of hatching of the larvae, but the effectiveness of biological products may be slightly lower than the use of chemical insecticides.

When working with pesticides, safety precautions must be observed and the waiting time for the aftereffect of the drugs must be observed, following the attached instructions. When caring for both young and actively fruiting berry plantations, it is necessary to correctly form the bushes. Every year (in early spring, in the phase of dormant buds), it is necessary to cut off (at the soil level) the unnecessary branches or branches lying on the ground at the same time, while removing branches infected with caterpillars. When pruning, no hemp is left, the cuts are covered with garden var. All cut branches are immediately burned. This technique has a beneficial effect on reducing the number of wintering caterpillars, allows you to reduce and control the pest population.

During flowering, the bushes of these crops should be examined in order to timely identify and remove wilted (inhabited by caterpillars) branches, grabbing 3-4 cm of their healthy part. In order to catch butterflies of currant glass during their summer, in the crown of each bush of currants and gooseberries, they hang 1-2 containers with fermented jam from black currant berries (diluted with water in a ratio of 1: 1).

Narrow-bodied currant goldfish

Narrow-bodied currant beetle (up to 9 mm long) with a narrow flat body of green color with a metallic sheen, damages, in addition to black and red currants, gooseberries and roses. It is ubiquitous where these plants are grown; damage to the branches of fruit-bearing bushes, for example, black currant, exceeds 15%. According to scientists, even the presence of one damaged branch of 2-3 years old in a currant bush reduces its yield by up to 15%, and gooseberry - up to 10%. This is caused by the chopping and shedding of the berries. The narrow-bodied currant beetle is thermophilic, chooses lighted places, is especially active in the hot hours of the day. Eating on currant leaves, he figuratively gnaws them from the edges. Females lay eggs mainly on the bark of 2-3-year-old branches (less often on leaf stalks) one at a time, covering them with secretions that form a membranous shield when they harden. After hatching (in July) from eggs, having passed development for 25-30 days, depending on humidity and air temperature, the larvae bite into the place where the egg shell is located, inside the shoots and grind holes into them, feeding on the core and partly adjacent layers wood. Legless beetle larva, yellow-white, slightly flattened, segmented. The first wave of larvae is noted during the period of picking black currant berries. Feeding for about two months, the larva gnaws a course 20-40 cm long, filling it with dry, brown excrement. It hibernates in this kind of insulated transition.

According to some experts, on the cut of the branch damaged by the larvae of the goldfish, it is clear that the passages made by them are filled with a brown wormhole, while when damaged by the caterpillars of the glass pan they are half-empty and black. It should be noted that middle and older larvae (up to 20 mm long) usually hibernate inside the branches of predominantly zero branching order. At the end of their body there are two short, thick, hook-shaped processes. 7-10 days after the steady transition of the average daily air temperature through + 5 ° C (usually in May), the larvae resume feeding. The first wave of pupating larvae falls on the period of inflorescences protruding and the first stage of flowering of black currants, and the most active - during the formation of its first ovaries. After 3-4 weeks, the beetles gnaw through the crescent-shaped holes in the branches to get out.

The branches inhabited by goldfish are identified in the spring, when they are quite clearly visible, especially sharply - during the flowering period, because the leaves on them do not bloom or bloom extremely slowly and subsequently wither. The pest develops in one generation.

Control measures

During the purchase, you need to carefully inspect the seedlings in order to exclude the skidding of the goldfish caterpillars along with them. Careful pruning of poorly developed branches and branches in spring with suspicion of colonization by a pest allows, according to experts, to significantly reduce the number of larvae (more than 50%). On cloudy days or in the morning and evening hours, when there is no summer of beetles (they hide under the leaves), they use shaking off the imago on a plastic wrap. This technique also significantly reduces the number of pests in the personal plot.

If the gardener adheres to strictly ecological methods of cultivating his crops, then it is desirable for him to have on the site several square meters, planted with dill and other odorous herbs that attract insects that parasitize on harmful objects, including the larvae of the goldfish. So, wasps from the Khaltsid family actively lay their eggs in the larvae of the goldfish, as well as in the pupae, from which their own larvae develop, which destroy the hosts.

If it is necessary to use chemicals to combat goldfish, experts recommend spraying the foliage of the bushes with an aqueous solution of actellik (15 ml / 10 l of water). They are processed three weeks after the end of flowering, this achieves a significant destruction of beetles that feed on leaves during this period.

Prevention of currant diseases

The first technique that works flawlessly on the health of currants is planting currants in a well-lit place, protected from the north wind. Lack of other shrubs and trees at a distance of 1.5 m.

Removing weeds, especially wheatgrass. Most infections and fungal spores are spread through weeds. Mulching and digging the soil are also effective against all types of infections.

Annual sanitary pruning in early spring can protect the plant from a range of diseases and pests. In spring and autumn, treat the bushes with drugs: copper sulfate, karbofos, Bordeaux liquid.

Gooseberry pests and control

Young shoots with delicate leaves and delicious gooseberries are to the taste and pests. The greatest harm to the berry harvest is caused by:

  • gooseberry fire
  • gooseberry sawfly,
  • gooseberry moth,
  • currant gall midge,
  • currant goldfish,
  • currant glass jar,
  • spider mite,
  • shoot aphid.

Being engaged in the prevention of diseases and the prevention of pests of gooseberries, one should not lose sight of the fact that the soil provides shelter for many larvae and pupae of pests. Sometimes it is enough to dig up the soil under the bushes and treat it with protective equipment to get rid of significant problems.

Gooseberry fire

The fact that the plant is affected by the fire becomes clear as soon as the supposedly ripe berries entangled in cobwebs appear on the gooseberry bush ahead of time. This is the result of the work of the larva, which eats the ovary, and then leaves the plant to pupate in the soil and develop into an adult butterfly.

Experienced gardeners recommend covering the soil under the bushes with dense material at this time and thereby preventing the larvae from burrowing.

On the same principle, another method of dealing with the departure of a fire is based. In this case, in early spring, the gooseberry bushes are huddled to a height of 10–15 cm, and after the beginning of flowering, when the danger has passed, the soil is removed. Butterflies cannot overcome such a thick layer of soil and die.

A good result, according to gardeners' reviews, is provided by butterfly traps: windows are cut in plastic bottles, fermented juice, kvass or beer are poured into one-third, and suspended. By the way, if bowls of beer are left on the ground, slugs will also gather there. Hand picking of the affected berries, spraying the bushes on the fifth day of flowering with an infusion of ash (the preparation method is the same as in the case of a spheroteka) and chamomile (100 g of dry chamomile flowers are poured in 10 liters of boiling water, cooled and processed) helps. In extreme cases, they resort to Actellik, Karbofos or Iskra M.

Gooseberry sawfly

In fact, under the name "sawfly", at least two pests are united, yellow and pale-footed, although there are several thousand varieties of them. The larvae of these insects are very voracious, infecting the leaves of gooseberries and red currants. Sawflies hibernate as pupae, and in spring the butterfly lays a new clutch on the leaves. The larvae that appear devour the leaves and leave the plant practically naked, with coarse veins sticking out. The sawfly goes through up to three development cycles per season.

Left without leaves, the bushes die, as the assimilation processes are disrupted; in the absence of a green leaf, photosynthesis does not occur.

For prophylaxis, gooseberry bushes in the spring are treated with odorous solutions containing tar or coniferous extracts, mulching of the root neck with pine needles is used. Plants are sprayed with insecticides before flowering. When pests are detected, biological protection measures are used: natural enemies of insects, nematodes are used. Antonem F and Nemabact concentrates are produced, which, in addition to nematodes, also contain bacteria that parasitize garden pests.

Gooseberry moth

The larvae and caterpillars of the gooseberry moth feed on the leaves of the plant, eating them up to the veins. Before pupation, the caterpillar twists around the leaf and falls with it to the ground. Mechanical collection of affected and suspicious leaves, weeding and mulching of the trunk circle can save the plant from pests. With significant pest damage, the bushes are sprayed with insecticides. For this, the most appropriate time is before flowering, immediately after bud break and after harvest. Produced insecticides such as Actellik and Iskra M have a wide range of effects, therefore, as a rule, they get rid of several types of pests.

Currant gall midge

Despite the telling name, currant gall midge, with success for its offspring, also encroaches on gooseberry bushes. Gall midge is a small insect; its larvae are the main danger for gooseberries. There are several varieties of gall midge: shoot, leaf, and flower. They differ in taste preferences and the location of the clutches.

Flowers, leaves and shoots infect different types of gall midges.

It is easier to prevent defeat by a pest than to deal with it. For prevention, the same agrotechnical methods are used as in other cases. Mulch the near-stem circle with the tops of tomatoes or spray the bush with infusion of the tops. One of the ways to prepare the infusion: chop 2 kg of fresh tomato tops, pour a bucket of boiling water and leave for 4 hours. Fragrant flowers are planted nearby - the gall midge especially does not like mint. Carrying out the autumn pruning, the affected branches are cut at the root, without leaving hemp. When working, they try not to injure the shoots.

Shoots affected by gall midge differ in shape from healthy ones.

Currant goldfish

Currant goldfish affects the shoots of currants and gooseberries, eating the core from top to bottom. Its larvae hibernate inside the shoots, and at the beginning of summer, adults fly out to lay new clutches on the leaves and bark of the twigs. The larvae that appear gnaw through the passages in the shoots, and the cycle repeats. Affected bushes do not grow and do not yield crops. To combat the pest, the affected branches are cut at the root and destroyed. As a preventive measure, only bushes purchased from reliable manufacturers are planted. When planting, agrotechnical recommendations are taken into account, weeds, fallen leaves are removed and broken branches are removed in time.

Currant glass

An adult glass moth is a butterfly measuring up to 25 mm in wingspan. It affects bushes of currants, gooseberries, raspberries. The larvae emerge from the laid eggs, which penetrate inside through cracks and lesions on the bark and gnaw through the passages. Affected shoots look drooping, then die. Back doors are visible on the cross section of the branch. Some larvae pupate in May and after two weeks form into a butterfly and fly out, some of the larvae hibernate inside the shoots.

Currant glassware affects currants, gooseberries, raspberries

As a preventive measure against the glass in the aisles of the bushes, odorous plants are planted: nasturtiums, calendula, marigolds, onions, garlic.

Experienced summer residents noticed that bird cherry attracts glass, so they do not recommend growing it in gardens.

When processing plants, trauma to branches and bark is avoided. Shoots are periodically examined. In the fall, after harvesting, the gooseberry twigs are slightly bent - healthy ones bend, and the shoots affected by the glass bottle break. They are cut to the ground and burned.

Spider mite

Refers to sucking parasites. It is located on the underside of the leaf, entangling it with cobwebs, and feeds on its juices. Affected leaves turn yellow and die. In hot and dry weather, the reproduction of spider mites is especially intensive, during the summer season they can give up to 8 generations. As a rule, it is impossible to notice ticks or their eggs with the naked eye.

For the prevention and control of spider mites:

  • weeds regularly and loosen the soil around the bush
  • odorous plants (marigolds, calendula or nightshade) are planted next to gooseberry bushes
  • harvested by hand and destroyed the affected leaves
  • plants are sprayed with infusions of odorous herbs (tansy, tobacco, garlic).

Spider mites are invisible to the naked eye

In the absence of the effect of traditional methods of treatment, they resort to more serious means of chemical protection, for example, Fitoverma or Vermithek, using these drugs either before flowering or after harvesting berries. Actellic is more effective as an anti-mite drug, but also more toxic. The choice of means of protection depends on the degree and mass of damage to plants by pests.

Sprout aphid

Aphids are perhaps the most common pest in our gardens. On rose bushes or zucchini leaves, her hordes indiscriminately devour leaves, buds, ovaries. She does not spare the gooseberry bushes either.

The shoot aphid is able to capture the bush, killing the plant

Of the popularly recognized means of combating aphids, it is worth mentioning mustard infusion. Pour four tablespoons of mustard powder with a liter of warm water and leave in a warm place for two days, then decant and bring the solution to ten liters. All plants are sprayed, not just gooseberries. One spray is often enough. Garlic-tobacco solution is also used. And for those gardeners who are desperate to achieve success in unequal pest control, they release the drug Biotlin, which destroys not only aphids, but also a number of other pests.

Diseases and pests of currants - signs with a photo, fight and treatment

The currant is a plant of the gooseberry family that is widespread in Europe, Asia and North America. All plant varieties are susceptible to various diseases, as well as attacks by pests, which, by their activity, contribute to a decrease in yield and lead to the death of shrubs. To protect plantations of currants from pests and diseases, one should know their main symptoms and manifestations, as well as methods of control.

Currant is a bush reaching a height of 2–2.5 m. Three - five-lobed leaves have sharp teeth at the edges. The bush blooms with carpal inflorescences, which consist of 5-10 small flowers with 5 petals, stamens and sepals. Berries about 1 cm in diameter usually ripen by the end of July. The shrub begins to bear fruit the next year after planting. The currant is shade-tolerant, but it develops much better in areas that are well lit by the sun. Most often, black, white and red currants are grown in culture, but yellow currants are gaining more and more popularity.

Currant berries contain vitamins, organic acids, macro- and microelements that are extremely important for humans. Black currant is beneficial for bronchitis, atherosclerosis, hypertension, vitamin deficiency, gastritis, renal and hepatic colic and other diseases. For the treatment and prevention of diseases, not only berries are used, but also flowers and leaves of a shrub. However, currants are themselves susceptible to diseases and pest infestations, so it is important to diagnose and treat them in time.

In order for the plant to please the gardener with a bountiful harvest, it is necessary to know not only the intricacies of care, but also the signs of currant diseases. The first symptoms are leaves that begin to turn yellow and fall off. In addition, the berries begin to dry and the trunk rot. You need to know how to properly treat currants.

Powdery mildew is a fungal disease. It is characterized by the appearance of a white loose bloom on young leaves, which gradually spreads to berries and old leaves. In this case, the bush must be sprayed with phytosporin or iodine solution. It is made in the following proportion: a bottle of iodine for 10 liters of water. Spraying can be repeated after 3 days. If this does not bring the desired result, then use a solution of copper oxychloride, copper sulfate or Bordeaux liquid.

A popular way to treat powdery mildew is to use a solution of soda ash with laundry soap. To prepare it, 50 g of soap and soda are diluted in 10 liters of water. Bleach, which is diluted in a proportion of 1-2 tbsp, also helps well. l. on a bucket of water.

With a disease such as anthracnose, reddish-brown spots appear on the leaves of currants, 1 mm in diameter, which gradually blur, covering an ever larger area. The disease often affects the leaf petioles, as a result of which they begin to turn brown, dry out and fall off in the lower part of the shrub. Quite often, anthracnose appears during the rainy season. Most often, red currants are susceptible to the disease. The disease can overwinter in fallen leaves, so in the spring it is very important to remove last year's leaves from under the bushes.

Currants, if they fall ill with anthracnose, should be treated as soon as possible. For this purpose, the bush is treated with a solution of Bordeaux liquid in a proportion of 100 g per 10 liters of water. Re-process the bush after harvesting.

With a disease such as white spot, mainly the leaves are affected. At the same time, they become covered with angular or rounded spots. At first they have a brown tint, after which they become white with a brown border. Basically, black currant suffers from this ailment. Bushes covered with white spots do not grow well, lose leaves early and give a poor harvest.

Treatment is carried out by spraying currants with phytosporin. Fallen leaves are collected and burned to prevent further infestation. In order to prevent white spot, microelements such as zinc, boron, manganese, and copper are added to the feed.

Very often, currants are affected by a disease such as goblet rust. With this ailment, the leaves are covered with orange-red blisters. The spores of the fungus reach the bushes with the help of the wind from the nearby sedge trees. High humidity is also a favorable environment for the onset of the disease. Leaves on the affected shrub turn yellow, then fall off. Berries also fall.

To cure the currants, the bush is sprayed. To do this, use 1% Bordeaux liquid, which should be sprayed with the shrub 3 times: when the leaves begin to bloom, during flowering and immediately after it ends. To prevent infection with this fungus, it is necessary to destroy the sedge growing nearby. In the fall, all affected leaves are raked into a heap and burned.

Columnar rust is transferred from coniferous trees. This fungus affects black currant especially strongly. The disease manifests itself in small yellow spots on the leaves of the bush. Orange cushion bubbles appear on the underside of the leaf. This disease is dangerous because the leaves begin to fall off ahead of time, the shoots grow worse, and the bush loses its winter hardiness.

The control measures are as follows: the affected bushes are sprayed with 1% Bordeaux liquid before the leaves appear, after flowering and immediately after harvest. When the first signs of columnar rust appear, the plants are treated with phytosporin. In autumn, leaves from diseased bushes are burned or buried in the ground.

Most often, white and red currants are prone to drying out of shoots. With this disease, shoots and branches dry out and die off. The disease manifests itself with small orange dots on the branches. At first they are practically invisible, but after a while they increase, turning into red-brown tubercles. When the spores mature, they turn black.

The fight against the disease should be started as soon as possible in order to preserve the plant and future harvest. For this, the affected branches are cut and burned. This saves the bush from infection. Places of cuts are treated with 1% Bordeaux liquid and covered with garden pitch.

Currants are often affected by gray rot disease. The disease spreads with rain and wind from affected fruits and infected branches. Gray rot appears with brown spots on the leaves. In addition, lumps of mold appear on the currant bushes. Most often, white currants are susceptible to the disease.

To get rid of gray rot, remove affected fruits, shoots and leaves, which are then destroyed. To prevent the disease, they get rid of weeds, observe the regime of feeding and watering.

Terry causes the infertility of currants. This disease is the most dangerous for the plant. Terry appears during flowering by the appearance of petals and leaves. The leaves have three lobes, not five. On the edge of the leaf, the denticles are larger and less frequent than usual. The veins are much smaller, they are coarser, and the leaf plate is thickened. The leaves become darker in color, and the smell of currants is not felt.

Flowering on an infected shrub is a week late, the inflorescences are narrow, elongated and very small, dirty pink in color, and can be completely green. The berries are not tied, and the inflorescences dry. Currants cannot be cured of terry, and therefore they are uprooted. Even with the defeat of only one shoot, you need to completely get rid of the bush.

Striped mosaic spreads with ticks and aphids, as well as if a diseased stalk was grafted onto a healthy bush. In addition, the disease is transmitted if the pruning of sick and healthy currants is carried out with one tool without disinfection. The leaves on the diseased plant have bright yellow patterns around the large veins.

This disease is incurable, so the affected bush is completely uprooted and burned.

Currants are often affected by various pests. Protection against their attack lies in the implementation of preventive measures. But if the bushes are already affected by insects, then you should not immediately use chemical agents, because they can harm the plants.

First you need to try folk remedies such as infusions, decoctions and sprays, many of which are very effective.

A kidney mite is a very dangerous pest that enters the site along with the seedlings. It does not tolerate high temperature and humidity, therefore it hides mainly in the ovaries.

Ticks are dangerous because they are carriers of many diseases (terry, mycoplasma). Affected bushes suddenly lose their immunity, become very susceptible to other pests and may die.

When the currant blooms, its buds begin to wither. Because of this, females of parasites crawl out into the fresh air and this is the only moment when the pests are defenseless. Pests begin to attack a young twig full of juices, in the sinuses of which they again hide and multiply. In the spring, the diseased bush grows its shoots unevenly, the leaves are deformed and noticeably lagging behind in development. In this case, the currants will give very few flower brushes, and most of the ovaries will never wake up.

To prevent severe damage to the bush, a thorough examination is carried out in early spring. This should be done before the buds open. Doubtful and infected kidneys are ripped off and burned. If the shoot has a lot of such buds, then they are cut off along with the shoot. The affected bush is sprayed with a solution of karbofos or colloidal sulfur. You can use tinctures of shag, dandelion, garlic. Spraying is repeated before and after flowering of the plant.

The spider mite most often lives on the underside of the leaf plate. Prefers hot and dry weather. The presence of a pest can be identified by a light cobweb covering the leaves. Affected leaves dry and fall off, and axillary buds begin to develop. Such shoots can freeze and die.

  • in spring, before flowering, the plant is sprayed with an infusion of onion husks, garlic or makhorka
  • remove all the weeds under the bushes, and in the fall they remove the fallen leaves and dig up the ground.

This pest leads to drying out of currant shoots. As a result, fruiting is weakened, and the berries become smaller. In a dried shoot, the larvae hibernate and pupate. At the beginning of summer, young beetles emerge and begin to feed on currant leaves. Then the females lay eggs in the bark of the shoots, and after 2 weeks the larvae emerge from them. They gnaw through the shoots and feed on the pith, making their way down the stem.

The fight against them is carried out as follows: dried and affected shoots are cut and burned. Three weeks after the currants have faded, they are treated with a solution of karbofos.

If the currant is affected by leafy gall midge, then you can notice this by the wrinkled, deformed leaves. The larva prefers to live in young leaves and feeds on the skin.The foliage, starting from the top of the shoot, becomes brown, curls and dries up.

  • the affected shoots are cut and burned
  • bushes are sprayed with chlorophos solution with the addition of karbofos
  • as a preventive measure, summer cultivation and autumn digging of the soil are carried out.

The shoot aphid lives in colonies. The larvae live in the subcortex of the young shoot in winter, and in the spring they spread throughout the bush. In the affected plant, young leaves dry up and die off.

To fight the pest, use a soap solution: 300 g of soap per 10 liters of water. To destroy aphids, spraying the shrub with a solution of Karbofos or Actellik is used.

The currant glass bowl is a small butterfly. Pest females are capable of laying up to 60 eggs in the cracks in the bark of branches. The caterpillars that have appeared gnaw through the core of the branches and make passages in them for wintering. By the next autumn, the glass cases reach a length of 2 cm, but do not go outside. Inside the currant branches, they spend another winter. In late spring, the larvae gnaw through the exit and pupate. After the end of flowering, damaged branches wither and dry out.

From the glass, Fitoverm, Akarin, Bitoxibacillin are used. If the bush is slightly affected, then you can cut off the affected shoots very shortly and burn them.

In order for the currant to get sick or be affected by pests as rarely as possible, it needs proper care. For prevention purposes, it is necessary to spray the bushes in the fall and remove the fallen leaves.

Currant glass jar and narrow-bodied goldfish - how to deal with them - garden and vegetable garden

To view the description of the insect, click on the photo or on the link.

Your garden and vegetable garden are under a constant, growing threat of ruin. And you don't pay any attention to it? Your enemies - pests must be destroyed. Pests in our gardens and vegetable gardens are a very serious problem that spoils our life during the harvest season, takes away the joy for our seasonal work.

Therefore, it is very important for a person who grows vegetables and fruits on their own land to know how to deal with parasites. The main habitat of all enemies of gardens and vegetable gardens is, of course, the soil. And therefore, it is in the soil that the overwhelming majority of pests winter. Although there are insects that spend the winter on the trunks of trees and shrubs, in various buildings. It is in the buildings that the larvae of all sawflies, beetles, pupae, ticks and weevils prefer to winter.

In the soil of the garden and garden at a depth of twenty or thirty centimeters, the Colorado potato beetle winters. Under it, at an even greater depth, an ordinary bear prepares itself for wintering. Flea beetles gather at a very shallow depth in the soil or under uncleared, fallen leaves. There comes a period in your garden between the harvested crop and the onset of a real winter, when the first snow falls and the first frosts bind the ground. This is the most favorable time to fight the enemies of your garden. It was at this time that most pests settle down for the winter, preparing their own moves and climbing into the soil to different depths.

And now is the time to apply some of the simplest and most effective methods of fighting and exterminating insects. The most effective method of combating parasites in the pre-winter time is digging the soil around the trunks of fruit trees, between the beds and on them. Such soil cultivation with a shovel allows you to extract most of the pests to the surface, where they simply freeze out or are destroyed by birds.

It is worth noting that if a large number of fruit trees grow on your land plot, then pests overwinter on their trunks and crowns. In the entire lower part of the tree, in cracks in the bark, in various crevices of wooden fences, caterpillars of the apple moth are arranged for the winter. On the trunks and thick branches between the wood and bark of trees, the larvae of the bark beetle overwinter in prepared tunnels.

The golden-tailed caterpillars braid the fallen leaves with dense, silky cobwebs and make nests for themselves, folding a few leaves. At the base of the buds of fruit trees, aphid eggs and copperheads are located in the stage. These pests prefer young trees and shoots.
