Video of processing currants and gooseberries. Today we have protection of plants from insect pests. Look at this currant, it has characteristic red swelling spots, many ask what kind of currant disease is it? This is a gall aphid, it hides on the back of the leaf, it is very small, smaller than an ordinary aphid, it is difficult to see it with the naked eye. Its peculiarity is that it hides under the leaves, if you spray, then turn each leaf and apply the solution exactly there.
In addition to the gall aphid, the common aphid, which settles on the tops of the shoots, twists them, also damages the currants. Now there are a lot of such aphids on black currants. There is another malicious pest that harms both currants and gooseberries - this is the currant and gooseberry moth. This insect infects the ovaries and fruits, the larva gnaws the fruit, it becomes reddish prematurely, it seems that it begins to ripen ahead of time, the damaged berries get tangled in a cobweb. From one fruit, the larva can pass into other berries, thus damaging a large number of fruits, thereby reducing the yield.
All these pests can be overcome at one time if our plant is sprayed with insecticidal preparations on time. Against the currant moth, gooseberry moth, it was necessary to spray before flowering. When the buds are first set, females begin to lay their eggs in buds, but they can lay eggs in small ovaries as well. On gooseberries, too, don't miss the moment and spray your plants against these pests.
What drugs can be used: in this case, I have "Inta-Ts-M" - this is a drug for a complex of pests, here weevils, and the Colorado potato beetle, and leaf beetles, and against those gooseberry pests that I named: aphids, thrips , whitefly, in general, the drug helps well. I have already used it many times and I can say that black aphids settle on my viburnum, and on roses, and ordinary green aphids on currants - it destroys all this. If caterpillars of currant and gooseberry moths have already appeared, then you can use "Lipedacite" there, it acts against the larvae.
How to use this drug: read the instructions carefully, because "Inta-Ts-M" is a pill, other drugs may have an ampoule, be sure to read the instructions on the back, do everything according to it, do not rely on your memory. In this case, we do this with this tablet: first we grind it into powder on solid, then we pour it into a common container. You need 1 tablet for 10 liters of water. Dip the tablet into a bucket, first pour a small amount of water, stir everything there well, only then add up to 10 liters. Then use the solution either with a hand sprayer or with a stationary sprayer. Adjust the fine spray so the droplets adhere and stay on the plants longer. Spray gooseberries and currants in the early morning or evening hours, be sure to use gloves. Gall aphids are mainly on the top of the shoots, spray it all on the back.
To scare off pests, you can put strong-smelling plants in the crown, you can use elderberry, it is good when it blooms, it has a characteristic unpleasant odor, insects feel it and they get disorientated, they do not understand where to fly. That is, they smell the elderberry, think that it is an elderberry, not a currant, and fly by. You can use chopped garlic, tomato tops, marigolds - they can even be planted under the crown. Stepsons of tomatoes, if you don't throw them away, but put them in jars in the crown, then the insects will think that tomatoes are growing here, not currants.
These are the ways to combat currant and gooseberry moth and aphids. The most important thing is not to miss the moment, as soon as the flowering is over, there are small ovaries, process so that in the future the harvest will go completely to you, and not to pests.
The basis of pest and disease control is compliance with the rules of agricultural technology. In a well-kept garden, there are no conditions for the development of pests and diseases. First of all, the bushes should not be thickened; for this, pruning is carried out in a timely manner and the damaged parts of the plants are burned. The autumn digging of row spacings helps to destroy a large number of wintering pests.
If, nevertheless, pests appear, one should not begin the fight against them immediately with the use of chemical remedies. In the case when there are few pests, you just need to collect and destroy them by hand. So, for example, moths are easy to collect. It is recommended to use infusions and decoctions of insecticidal plants, which are less harmful than pesticides. Only when absolutely necessary can you resort to chemical protective measures.
One of the most dangerous and harmful pests of black currant. The surest sign of the appearance of a bud mite on currant bushes is strongly swollen buds. In the spring, such buds do not bloom, but only loosen up so that the mutilated rudiments of leaves are visible inside. Subsequently, the damaged buds gradually die off and dry out, which leads to significant crop losses.
Each swollen kidney can contain up to several thousand mites. Another sign of a bud mite infestation of bushes is a changed color and shape of the apical leaves, which become darker than normal, glossy, leathery, and deformed. The damage is noticeable already in July - August. The harmfulness of the kidney mite is enhanced by the ability to tolerate the infectious onset of the black currant disease - terry. Every gardener should know how to deal with a kidney mite on currants.
1. Early spring (before the tick leaves last year's buds) cutting of infected shoots and burning them.
2. Spraying currants during the period of throwing flower brushes with 2-degree ISO or a suspension of colloidal sulfur (75 g per 10 l of water).
3. After flowering, spraying with 1-degree lime-sulfur broth or 1% aqueous suspension of colloidal sulfur.
4. Spraying with 0.5% ether sulfonate or 0.3-0.4% tedione during the discard period and immediately after flowering also reduces the number of buds damaged by the mite.
If damaged currant aphid the leaves at the top of the currant shoot are wrinkled and twisted. A large number of light green insects are located on the underside of the leaves and the tops of the shoots. We all know that aphids are a dangerous pest and we must be able to get rid of it.
1. In the spring (before the swelling of the buds), to destroy the hibernating eggs, spraying the bushes with 3% nitrafen.
2. Spraying gooseberries and currants with chlorophos (20 g per 10 l of water) with the addition of karbofos (30 g) or trichlorometaphos-3 (20 g).
3. Spraying the bushes with a 0.2% solution of anabazine sulfate with the addition of 0.4% soap during the appearance of aphids.
If wrinkled disfigured leaves appear in the upper part of the shoot in mid or late May, then these are characteristic damage by the larva leaf gall midge... The larva lives in folded young leaves, feeding on their juices and scraping off the upper skin. In this case, the youngest leaves at the top of the shoot turn brown or dry out.
Control measures against gall midges:
1. Cutting out shoots damaged by stem gall midge immediately after the appearance of damage and burning them immediately.
2. Autumn digging and summer soil cultivation.
3. Spraying of currants and gooseberries with chlorophos (20 g per 10 l of water) with the addition of karbofos (30 g) or trichlorometaphos-3 (20 g).
This polyphagous pest can cause significant damage to currant leaves. Damage begins to appear noticeably in early to mid-May, before flowering. The leaves become whitish or reddish-brown, on the underside of the leaf blade appears spider mite... With a strong infection, the leaves stop growing, turn brown and dry out. With a strong defeat by a spider mite, the growth of the plant is weakened, the activity of the leaves decreases, the ripening of berries is delayed.
1.Gathering and burning leaves, digging up the soil under the bushes.
2. Spraying the bushes with 50% karbofos at the rate of 20-30g per 10l of water during bud break and immediately after flowering.
3. You can treat the bushes with a decoction of onions (garlic) or a sulfur preparation.
Damages branches. Caterpillars mine branches of red and black currants. From mid-June to the end of July, butterflies years occur, which lay eggs on shoots near the buds, and more often near cracks and knots. The hatched caterpillars penetrate into the branches, eat out the core and fill the passages with dark brown excrement. Caterpillars subsequently move from young branches to adults. By autumn, the caterpillars often descend to the base of the branches and remain there for the winter.
Damage to plants is usually found in the second year of the caterpillar's life, at the end of flowering and especially at the beginning of berry ripening, when young shoots and brushes with ovaries begin to wither, as it were, suddenly. In the future, the damaged shoots die off and dry up.
Fight against currant glass rather difficult due to the hidden lifestyle of the caterpillar, little noticeable manifestation of damage at the beginning of infestation and the two-year development cycle of the pest. An effective measure to combat currant glass is the correct and timely pruning of bushes with the simultaneous removal and immediate destruction of all cut branches infected with caterpillars. Old branches are cut off near the ground, leaving no stumps. It is necessary to identify infected branches in a timely manner, that is, during the flowering period of plants (early May). Withering infected branches are cut to a healthy part.
1. In early spring or autumn pruning of bushes, cut branches damaged by caterpillars are simultaneously removed and immediately burned. Old branches should be cut off near the ground, leaving no stumps.
2. During the flowering period, it is necessary to periodically inspect the plants and cut out the branches damaged by the glass to a healthy part.
3.After flowering, the bushes should be sprayed with the preparation "Iskra Double Effect" (1 tab. Per 10 liters of water) or 0.1% "Aktara", or infusion of mustard, tops and stepchildren of tomatoes, tansy, celandine.
A dangerous pest that has recently spread widely on currants. Outwardly healthy shoots in the middle of summer suddenly dry up or break off easily. Small orange-yellow or pink larvae can be found under the bark stem gall midge, as a result of the settlement of which the escape breaks. Below the dried part, at the place of the fracture, a dent is formed and the bark darkens, and often the wood on old branches, the damage looks like a wound with swollen edges. The stem gall midge gives several generations. The spring generation most often damages the 2-3-year-old branches and root zero shoots, the gall midges of the summer generation also infect the shoots of the current year.
Treatment of bushes with the same preparations as against leafy currant gall midge, with the only difference that two weeks after harvesting the bushes are re-treated with karbofos against the second generation of stem gall midge. Damaged shoots are cut and burned.
At the beginning of the setting of black currant berries on the bushes, you can find berries with a characteristic ribbed shape. They are much larger than healthy ones and, as a rule, stain earlier, and the infected ovaries do not show visible signs of damage on the outside. It is harmed by larvae (caterpillars) sawfly, which feed inside the ovaries, destroying the seeds, while the pulp of the berries is slightly damaged. The damage is most pronounced in the second half of June.
In the first half of July, about 25-30 days after hatching, the larvae leave the berry, gnawing a round hole outside, most often at the stalk, pupate and remain for the winter. After the larvae emerge, the wormy berries fall off prematurely. Due to the hidden lifestyle, the fight against sawiliac is rather difficult. Digging under infected bushes is a good practice. It is necessary to collect and destroy wormy berries before the larvae emerge from them.
1. Spraying the bushes with 0.2-0.3% chlorophos.
2. Autumn digging of soil.
The larva damages the shoots of currants (black, white and red) and gooseberries. Have an escape damaged currant gold, the top begins to dry out, quickly covering the entire shoot. As a result, the fruiting of the bush is weakened, and the berries become small. The larva hibernates inside the damaged shoot. The larvae are flattened, widened at the head. They pupate in the shoot.
The emergence of young beetles from shoots usually occurs in June, but in years with an early and warm spring, they appear at the end of May. For some time they feed on currant and gooseberry leaves. 7-10 days after emergence, female beetles lay their eggs on the bark of one-year and two-year shoots, less often on older branches and on leaf petioles, covering them with their secretions, which solidify on the bark in the form of a hard oval shield. In 13-16 days after oviposition, larvae emerge from the eggs under the scutellum, which bite into the shoots and, feeding on their core and wood, descend down the stem.
Cutting and burning damaged shoots.
Hibernates in the stage of small violet-red eggs under the shields of dead females. During the flowering phase of currants, vagrant larvae hatch from the eggs. They stick to the bark of branches, are covered with a shield and suck out the juice. Affected branches weaken, sometimes dry up. The willow scabbard gives one generation per season.
1. Abundant spraying of bushes in spring on dormant buds with 2-3% solution of 60% nitrafen paste at the rate of 200-300 g per 10 liters of water.
2.Early in spring or autumn, the branches are cleaned with a brush, with a strong spread of pests, the branches are cut and burned.
3. Immediately after flowering, the currants are treated with 50% karbofos at the rate of 20-30 g per 10 liters of water.
A widespread dangerous disease of black currant. Bushes severely affected by this disease do not bear fruit at all. Flowers in diseased plants of an ugly shape. Disease terry slowly spreads through the bush, and therefore on the same plant there can be both diseased and healthy flowers, flower brushes, shoots and even individual skeletal branches at the same time. In addition, on patients with terry bushes, very swollen buds are very often found - this is a sure sign of their defeat by the kidney currant mite, which is the carrier of terry.
Bushes affected by terry usually do not heal. The disease intensifies and progresses every year, as a result, the bush becomes completely diseased and sterile. Therefore, diseased bushes must be uprooted, removed from the garden and destroyed. It is best to identify affected plants in the spring, during flowering.
To prevent the spread of terry, it is necessary to harvest cuttings when propagating currants only from healthy bushes, on which no signs of the disease have been observed for 3-4 years.Since the main vector of terry is the kidney currant mite, it is very important to timely and thoroughly combat this pest by chemical, mechanical and agrotechnical methods. ...
Currant anthracnose (muhosed) is widespread throughout Russia. This fungal disease is expressed in the appearance of very small brown spots on the leaves (conidial sporulation of the fungus). The leaf tissue turns brown, the leaf dries up and falls off prematurely.
Anthracnose also affects leaf petioles, young shoots, and peduncles. Anthracnose reaches a strong development in the second half of summer (end of July - August). Mature leaves are distinguished by a particularly high density and intensity of infection. The fungus penetrates into the leaves mainly from the lower side. The first signs appear on the lower leaves and in the lower part of the bushes - in places close to the overwintering of the parasite.
The mushroom hibernates on fallen infected leaves. Spores spread with water, possibly spread by insects. Anthracnose develops much weaker in years with dry and hot weather. The black currant varieties Golubka, Primorsky Champion, Zoya, Koksa, Minai Shmyrev, Belorusskaya Sweet, Seedling Golubki are less affected by anthracnose. Varieties Nadyadnaya, Vystavochnaya, Leah Fertile are affected moderately and weakly, but in some years they can be severely affected. The old Neapolitan variety is very strongly affected by anthracnose. Due to severe anthracnose disease, this variety often has weak bushes and low yields. Variety Bradthorpe is usually slightly affected, but in some years it is moderately affected.
Red currants are very sensitive to anthracnose. The leaves of many unstable varieties fall off, even if there are several spots on them, until the berries are fully ripe. The varieties Red Cross, Feya fertile are especially strongly affected. The varieties are more resistant to anthracnose - the descendants of rocky and red currants: Gollandskaya krasnaya, Pervenets, Viktoria, Varshevich, Yuterbogskaya. Currant varieties strongly affected by anthracnose have reduced winter hardiness.
1. In early spring or autumn, after the leaves have fallen, they are sprayed with a 3% solution of 60% nitrafen (30-40 kg / ha, bushes and soil under bushes).
2. In summer, use a 0.4% suspension of 80% cuprozan (3-4 kg / ha) and 1% colloidal sulfur (3-4 kg / ha). It is sprayed before flowering, then after flowering and after 10-12 days, the fourth time is sprayed after picking berries, while the underside of the leaf is necessarily treated. A 1% Bordeaux liquid is also used.
3. Agrotechnical measures to protect against diseases are reduced to the collection and destruction of fallen leaves, timely digging and plowing of the soil under the bushes, embedding the top layer to a depth of 10 cm, regular destruction of weeds, thinning thickened plantings.
Powdery mildew in the last decade has become one of the most harmful diseases of the currant. Studies have revealed that a specialized form of the pathogen of American powdery mildew develops on currants, however, mutual infection of currants and gooseberries is possible.
Powdery mildew appears earlier on gooseberries and develops at a faster pace than on currants. The causative agent - a marsupial mushroom - is confined to age-young tissues, affecting growth points, young shoots, leaf stalks, leaves, buds, berries. Initially, the affected areas are covered with a white powdery bloom from the superficial mycelium and conidia of the fungus. Later, the mycelium turns brown. As a result of damage to the growth point, shoots stop growing, internodes are shortened, leaves become small, often ugly. The bushes are weakened and, if severely damaged, die after 2-3 years.
The fungus in its development has a summer stage (conidia) and a wintering stage (fruit bodies). During the summer, conidia develop up to 10-11 generations, causing repeated infections. The mushroom hibernates on fallen leaves and berries. In the spring, after overwintering, ascospores again infect currant plants, their young growths and ovaries. The disease manifests itself in early summer, reaching its maximum development in July - August.
Identifying and developing varieties with stable powdery mildew resistance is of paramount importance. Very few resistant varieties are currently known. In connection with the emergence of new biotypes of the fungus, varieties that were previously considered resistant become susceptible. This is the case with the zoned variety Bredthorpe (Karelskaya). Relatively resistant varieties have also become more affected. The degree of damage depends on the variety and growing conditions (agrotechnical, weather conditions and plant protection measures). Studies have established that adult leaves of all varieties of currants are resistant to powdery mildew. Long-growing varieties and conditions conducive to long-term growth are favorable for infection. Depending on the growing conditions, the degree of damage to the variety varies. The varieties Bredthorp, Belorusskaya Sweet, Seedling Golubki, Primorsky Champion, Golubka, Neosypayushchaya, Black Lisavenko are relatively resistant. Variety Pamyat Michurin is strongly affected in different conditions. Varieties of the Northern European ecotype (Oyebun and others) are distinguished by high resistance.
Red currants has a shorter period of shoot growth, and the degree of damage to its varieties is lower than that of black. However, shoots with longer growth can be severely affected in some years, which is also typical for shoots with protracted growth and forms of golden currant.
1. In early spring before bud break or in autumn after leaf fall, spraying with 2-3% solution of 60% nitrafen (30-40 kg / ha).
2. Before flowering and after harvesting, the bushes are sprayed with a 0.1% suspension of 25% caratan (0.8-1 kg / ha) or 50% benlate (0.8-1 kg / ha).
3. After flowering, spraying is carried out with a 1% solution of colloidal sulfur (3-4 kg / ha).
4. With a strong development of powdery mildew, after 7-10 days, spraying is repeated with one of the above preparations.
5. You can spray with soda ash and soap (50 g of soda + 50 g of soap per 10 liters of water), infusion of slurry or hay dust (1 part of manure or hay dust is poured with 3 parts of water, insisted for 3 days, diluted three times, filtered and sprayed ).
Septoria, or white spot, is ubiquitous. It mainly affects the leaves, which are covered with rounded or angular spots (2-3 mm in diameter), first brown and then white with a narrow brownish border. On the spots there are small black dots - the pycnidia of the parasite. Severely damaged bushes lose all leaves ahead of time, stagnate, and sharply reduce the yield. The main source of infection is fallen leaves.
Control measures with disease the same as with anthracnose.
Goblet currant rust is a fungal disease that is widespread. It is especially dangerous in areas where sedge grows - an intermediate host of the parasite, without which rust cannot develop. In spring, on sedge, where the mushroom hibernates, rust spores appear, which are carried by the wind to the leaves and fruits of currants and infect them. With a strong development of rust, premature leaf fall, spoilage and fall of berries can be observed. In wet years, currant leaves are affected by 78%, ovaries - by 68%.
Control measures with disease the same as with anthracnose. A radical means of control is the destruction of sedge.
Chemicals must be used with great care. Agronomists recommend applying chemical remedies before flowering. After that, it is desirable to apply folk and biological methods of processing and protecting plants. Read about the causes of drying currants.
Copper sulfate salt has the following types of actions:
The drug is a blue granules. The first spraying is carried out at the beginning of March, when the average air temperature exceeds + 5 ° C.
Depending on the purposes of processing, the proportions of dilution of copper sulfate also change.
Classic proportions - 100 grams of substance to 10 liters of water. Spraying with this agent is sufficient to carry out 1 time in 5-6 years. Vitriol is an excellent antifungal drug. To disinfect the currants, spray about 1.5 liters per bush. Read about the processing of currants with ammonia here.
A solution of the drug in a proportion of 100 grams per 10 liters is used to disinfect the root system of seedlings. For this, the newly acquired planting material is placed in the solution for 3 minutes.
The treatment of the bush is carried out with a solution at the rate of 2 grams per 10 liters of water. With such quantities, copper sulfate effectively fights against fungal spores and pests, but does not harm leaves and bees.
Iron vitriol is very effective against diseases such as powdery mildew, gray mold, anthracnose and rust. When using this fertilizer, there is a delay in the growing season, but for currant crops this is more a plus than a minus. This lingering state allows the shrub to survive the spring frosts.
When disinfecting and fertilizing the soil, it is necessary to mix 100 g of ferrous sulfate and 10 kg of compost or manure. Iron vitriol, like copper sulfate, does not penetrate into plant tissues and is easily washed off by sediments.
This drug has been well known since the second half of the 19th century. Its main ingredients are copper sulfate and lime. The tool can be purchased in specialized stores or prepared by yourself. The proportions are as follows: 10 liters of water, 100 grams of copper sulfate and 150 grams of lime. The water is mixed with lime, after which the copper sulfate salt, previously diluted in the liquid, is added to it.
The drug has proven itself well against fungal diseases, spotting, rust, septoria and anthracnose. Processing is carried out in 2 stages:
Urea or urea is a well-known fertilizer with a high nitrogen content (46%). Urea is a light-colored granules that dissolve well in water and are odorless. The fertilizer begins its pest control immediately after application to the soil. How to process currants during flowering from aphids read here.
The main advantage of urea is that it can be used both in the open field and in greenhouses.
Urea is dissolved in warm water at the rate of 500-700 grams per 10 liters. Consumption 2-3 liters per 10 m². Spring processing is aimed at destroying pests such as aphids, honey beetles, flower beetles, and weevils. Spraying in the fall is a good prevention of fungal diseases, scab and insects that have gone to winter under the bark.
Fertilization with urea is carried out both for young seedlings (45-50 g for a bush) and for adult crops (25-40 g for each shrub), while feeding is done in 2 stages: in early spring and 2 weeks after the first procedure.
This folk remedy is used throughout the spring and summer period. Peeled garlic (100 grams) is infused in 1 liter of warm water, after which 15 grams of grated laundry soap and 5 liters of water are added to it. The consumption of the product is approximately half a liter per 1 shrub.
Also used are finely chopped garlic cloves infused in 1.5 liters of water. The mixture is filtered and brought to 10 liters. The infusion works effectively against scale insects, whiteflies, worms and ticks.
Tar and laundry soap is often found in recipes for folk remedies against pests and diseases.
A mixture of soap and soda ash will cope well with a disease such as powdery mildew. To obtain a solution, it is necessary to take 50 grams of each substance and apply it to the areas affected by the disease. Find out why currant leaves curl at this link.
Another effective recipe is a combination of wood ash and laundry soap. To do this, you need to take 50 grams of grated soap and gently mix it with ash, infused for 24 hours. The approximate ratio of ash and liquid is 1.5 kg per 10 liters.
A solution prepared by mixing 1 liter of warm water and 30 grams of laundry soap will successfully solve the problem with such a pest as aphids.
When using tar soap, you need to take 40 grams of grated substance and dilute it in the same amount of water (1 liter). Spraying is best done in dry, calm weather.
To cope with ticks and butterflies that overcome currant bushes, a tool consisting of 2 parts of kerosene, 2 parts of tar soap and 12 parts of liquid (water) will help. In the presence of laundry soap, 40 g of this product is diluted in 1 liter of water, into which an additional 40 ml of alcohol is poured.
It is effective against pests such as mealy worms, scale insects and aphids. To obtain a solution, it is necessary to pour 100 g of citrus peels with 1 liter of water. The mixture is infused for 5 days. The container with the liquid must be protected from direct sunlight. Processing is carried out 3 times with a break of 14-15 days.
Chemicals are a first aid to plants for diseases and pest attacks. Each drug works in a certain period, so before processing, be sure to read the instructions for use and prepare the solution strictly according to the recommendations indicated on the package. The concentrated formulation burns foliage and other parts of the plant and can do more harm than disease. Learn about the characteristics and description of the grape variety Zaporozhye Kishmish here.
This popular drug has a short-term effect on pests. The composition does not lose its properties within 5-10 days and then completely collapses. Malathion is a base chemical related to organophosphorus compounds. It is used for the production of many insecticides. Substance with a pungent odor, which gradually disappears after spraying. This material will tell you about the features of growing Golden currant.
Chemical that protects plants from powdery mildew and rust. The impact is based on the use of penconazole in the composition. According to its properties, Topaz is a systemic fungicide. It is used to protect several types of plants. The chemical retains its properties for 4 years. It is used for the treatment and prevention of coccomycosis, gray and fruit rot, powdery and downy mildew.
The duration of the drug after treatment is up to 18 days, but the most active effect on the disease is within 4 days. The chemical has a high-speed effect on fungi, it is able to stop their reproduction already several hours after treatment.
The solution can reach the most confined areas of the plant and protect the vulnerable spots of shrubs.
This modern drug is a contact insecticide. Able to destroy all known pests of currants, regardless of the type of their food system. Low hazard to humans and animals. Aktara is a chemical that can kill aphids and other parasites in 1 spray.
In terms of concentration, the drug is preferable to analogues. To prepare 10 liters of solution, you will need to stir 2 g of the substance in water. But it must first be diluted in a small volume of water, and then the bucket must be filled completely. The properties are based on the use of thiamethoxane in the production of actara.This substance inhibits the basic processes of the nervous system, causes paralysis and death of pests.
The solution is fed into the structure of currant surfaces for 120 minutes, and when eaten, it penetrates into the digestive system of aphids. Insects are destroyed immediately after direct contact with the solution.
It is an antifungal fungicide that protects plants with a 100% guarantee. The drug is sold in tablets, depending on the required concentration; to prepare a dose of the drug, it will be necessary to dilute up to 20 tablets. Read about the features of growing onions on a feather at this link.
This Danish drug belongs to the group of organophosphorus insecticides, due to its characteristics and properties, it allows you to cope with any garden pest on currant bushes. Produced in ampoules with 47-57% concentrated emulsion. The volume can vary from 5 ml to 5 liters of the drug. For household farms, it is not recommended to purchase an insecticide in a large container, for such purposes it is better to use a package for preparing 5-10 liters of a working solution.
Biological plant protection agent. It is recommended to use it during flowering and fruiting of currant bushes - this drug affects only pests. It contains a large number of microorganisms, spores of fungi, natural enemies of insects. This makes it harmless to plants and humans. The main task is to deprive food, slow down development, prevent reproduction and cause a complete eradication of the problem.
A wide range of the drug's effect on pests helps protect currant bushes from all types of parasites. The chemical is active for 2 hours, then, under the influence of light radiation, it begins to lose its healing properties. To protect the currants from aphids, it is enough to prepare a solution of 2 ml of the drug and 1 liter of warm water. This article will tell you about the features of growing Lorano grapes.
With the help of Fitoverm, gardeners are able to destroy aphids within a few days. The chemical blocks the nervous system of pests, causes complete paralysis of muscle tissue and the death of insects.
Domestic brand, drugs are produced to combat pests and diseases of currants. When preparing the solution, you should strictly follow the rules for the dilution and use of the product. The drugs have been produced for a quarter of a century, and a line of formulations has been launched for the simultaneous preventive treatment of currant bushes with fungicides and insecticides.
This drug works well for butterflies, but is harmless to pest larvae. The processing period is spring, during the summer of females and their laying of eggs. But for aphids or moths on currant bushes, this remedy shows good results. Available in the form of tablets, only one is needed for 10 liters of water. Experienced gardeners recommend reducing the water volume to 6-7 liters or dissolving 2 insecticide tablets. If the solution is needed in a small amount for processing 1-2 bushes, it can be diluted, observing the ratio of half or a quarter of the product to water.
The tool belongs to preparations for protecting currants from diseases. It belongs to the class of aminopyromidine solutions. In addition to the detrimental effect on the pathogenic mycelium, the remedy heals currant bushes. It is especially often used to protect garden shrubs and other berries. The first spraying cycle is carried out at the stage of the beginning of the opening of flower buds. Re-processing is carried out 14 days after the first. The average consumption rate for 1 strong currant bush is 2-3 liters. the drug is active for 10 days after spraying.
High-quality processing of plants is impossible at air temperatures below 30 degrees Celsius. The optimum heating level for plants is up to 100. Temperatures over 250 will not allow contact fungicides to reliably protect plants. This factor must be taken into account in the summer.
This is one of the most popular contact fungicides among gardeners. The basis of the preparation is colloidal sulfur. It is used to protect against diseases as a contact fungicide, but it is used as an acaricide, a compound to protect currants from ticks. The drug is produced by the joint venture "August" jointly with the firm from Switzerland "Syngenta". The main substance that affects the mycelium is sulfur granules, its part in the total mass of the substance is 800 g for each kg of the preparation.
Actively fights against common and American powdery mildew, mites on currant bushes. The protective period of one treatment lasts for 7-10 days.
This remedy acts on fungi and protects plants from disease. With its help, it is recommended to process vegetable and flower seeds, as well as currant seedlings before planting on the site - this will protect the garden from fungal diseases. For the treatment of adult plants, it is used during preventive maintenance, using the systemic effect of the drug.
Destroying fungi during the first few days, the agent acts as a defense for several more weeks. The destruction of the mycelium of fungi occurs at the intercellular level, while the development and spread of the mycelium slows down or completely stops.
This is a means of fighting viruses and fungi on the shrub. Protects currants and other types of garden plantings from bacterial cancer. To prepare the solution, you will need to dilute 20 small tablets in a bucket of water and treat with it not only the crown of the plant, but also the soil in the aisle and under the bushes. When carrying out spring processing, it is recommended to destroy wintering myceliums by watering the soil. For these purposes, the consumption rate is reduced to 5 tablets per 10 liters of water.
Chemicals can hardly be called harmless, so many gardeners prefer to deal with plant ailments using folk methods using natural remedies. We will tell you how you can treat currants and gooseberries from diseases and pests.
Infusions of garlic, tobacco, onion husks have proven themselves well.
Infusions and decoctions to combat various plagues of plants can be prepared in different ways. In the article, we will present the most popular and effective recipes for these folk remedies. Of course, they will not cope with viral diseases, but fungal diseases and many pests will be within their power.
Pour 400 g of dried tobacco or makhorka leaves with 10 liters of hot water and leave for two days. After this time, strain the infusion through cheesecloth or nylon cloth and squeeze gently. Dilute the resulting liquid with water (in a 1: 1 ratio) and add 50 g of soap for every 10 liters of solution.
The tobacco infusion is not stored - it must be used immediately after preparation. This folk remedy is effective against kidney mites, aphids, sawflies, gooseberry moth.
Also, before flowering and after harvesting, it is useful to pollinate shrubs with tobacco dust. For 10 square meters, 30-50 g of powder are consumed.
To destroy kidney mites and aphids, currant and gooseberry bushes are sprayed with garlic infusion, which is prepared from 400 g of freshly ground garlic heads and 10 liters of water. The components are well stirred, filtered and the resulting liquid is immediately used, that is, the garlic does not need to be infused for a long time. When spraying berry bushes on 10 sq.m. consume 1 liter of garlic infusion.
You can prepare an infusion from 100-150 g of crushed dry leaves and scales of garlic. Pour 10 liters of water over them and leave for 24 hours. Then use this remedy immediately.
Plants are recommended to be processed in the evening or in cloudy weather.
This weed has powerful bactericidal and insecticidal properties. 3.5-4 kg of fresh crushed shoots (or 1 kg of dried raw materials), pour 10 liters of water, cover the container with a lid and leave in a warm place for 1.5 days. Then strain the infusion and use for spraying currants and gooseberries.
Dried shoots of celandine can be crushed into powder and used for dusting shrubs.
Infusion of dry mustard helps well against glass, moth, sawflies and other pests. Pour 200 g of powder with 10 liters of water and leave for two days. Then dilute the resulting liquid with water in a ratio of 1: 5 and use for treating bushes.
In order for the product to stick better to the leaves of plants, it is recommended to add soap to the mustard infusion (40 g per 10 liters of the finished solution).
Ash helps fight moths and sawflies, but is most effective against powdery mildew. To do this, pour 300 g of ash into 10 liters of water and leave for two days. Before spraying the plants, 40 g of laundry soap can be added to the ash infusion for better adhesion to the leaves.
This natural insecticide is effective against aphids. Pour 200 g of onion husks with 10 liters of warm water and leave for 12-15 hours. Then strain the infusion and spray the infected plants with it. The product must be used on the day of preparation. It is better to process bushes in the evening.
All parts of the plant are suitable for preparing the broth: stems, stepsons, leaves in dried or raw form. Take 3 kg of fresh chopped tops, pour 10 liters of water, let it brew for 3-4 hours, then simmer for 30 minutes. After this time, cool the broth and strain. Dilute 1: 4 with water before use.
Dry tops will need less: 1 kg per 10 liters of water. Insist for 4-5 hours, then boil over low heat for 2 hours. Then cool and strain. Dilute the broth with water in a 1: 3 ratio.
It is better to use the decoction of the tops immediately, but if necessary, you can store it for up to six months in tightly sealed glass bottles in a cool place.
For better adhesion, 30 g of laundry or green soap (based on 10 liters of solution) should be added to the broth before spraying.
Tansy does not like currant glass, gooseberry moth. To prepare a decoction of 1 kg of fresh plants, pour 10 liters of water, boil for 2 hours, strain and add 40 g of soap before use.
Fill a 10 liter bucket with 1/3 of hay, add water to the brim and leave for 3 days. Then dilute the infusion with water in a ratio of 1: 3 and strain.
The scheme of spraying bushes from diseases and pests
Pest or disease
Signs of plant damage
Time and frequency of treatments per season
Leaves, stems and fruits are covered with a white bloom. Later, its color turns brown.
2-3 times with an interval of 5-7 days
Large swollen buds, similar to small cabbage "heads"
5-6 times. From the beginning of budding to the beginning of flowering and after it
Caterpillars in the shoots leave wormholes, which causes the branches to stop growing, dry up and die.
1-2 weeks after flowering and then 2-3 times with an interval of 7 days
Butterflies lay their eggs in flowers. After hatching, caterpillars eat berries and leaves, braiding them with a cobweb.
After flowering 3-5 times at intervals of 5-7 days
Aphid colonies usually accumulate on the underside of the leaf. Shoots stop growing, leaves curl.
After flowering every week until the berries are fully formed
In spring, the adult gooseberry sawfly larvae eat the leaves. The blackcurrant sawfly damages the berries: they swell and then fall off.
After flowering 3-5 times at intervals of 5-7 days
In the habitats of the gall midge larvae, dark spots and cracks appear, the branches of the bushes dry up and break off.
After flowering 3-5 times at intervals of 5-7 days
If folk remedies do not help to cope with these misfortunes, use industrial (chemical and biological) drugs for diseases and pests of currants and gooseberries.

Redcurrant aphid - Cryptomyzus ribis (order Homoptera, family Real aphids). Distributed everywhere. Damages gooseberries and currants (black, red and especially golden). Wingless adult 1.9-2.2 mm long, fusiform, lemon-yellow in color, sap tubes 2.5-4 times longer than the tail.
As shown in the photo, the larvae of these pests of gooseberries and currants are yellowish:
Eggs overwinter on annual branches, as well as in cracks in the bark of 2-3-year-old branches. In spring, the larvae feed on the underside of the leaves, resulting in cherry-red bumps (galls) on the leaves. During the period of mass flowering, founding females appear, which hatch up to 90 larvae. A characteristic feature of aphids is that they feed only on young leaves, the formation of galls on them leads to a significant decrease in photosynthetic activity. 6-7 generations of aphids develop on currants. Later, winged females appear, which fly from currant bushes to herbaceous plants of the lamb family and continue to multiply on them.
Protection measures: To combat these pests, currants and gooseberries are treated with bi-58 new, karate zeon, biotlin, fitoverm, etc. It is necessary to eradicate weeds of the Yasnotkovy family.
These photos show how to control gooseberry and currant pests:
Willow scale - Chionaspis salicis (order Homoptera, family Scale). Inhabits shoots of currants, gooseberries, as well as many tree species and shrubs. As a result of the intensive colonization of shoots with these pests, the bushes weaken and gradually die. The female is covered from above with a dense, grayish-white, pear-shaped shield. In the male, at the larval stage, the scutellum is elongated, with two grooves. Eggs overwinter under the scutellum on the branches of bushes. The beginning of hatching of larvae from eggs and their dispersal along the shoots coincide with the budding of currants, the dispersal continues throughout the flowering period. Larvae of the 1st instar (vagrants) are red, with well-developed three pairs of legs, move along the shoots in search of a convenient place for feeding. Having begun to feed, the larva becomes immobile. At the end of summer, females fertilized by males lay eggs under the shield, which remain for the winter. Fertility is 40-80 eggs. One generation develops in a year.
Protection measures: cutting of branches inhabited by willow scabbard. And how can currants and gooseberries be treated from these pests? Spraying with insecticides (danadim, fufanonnova, fufanon, etc.) during the hatching period is recommended.
Gooseberry yellow sawfly —Nematus ribesii (order Hymenoptera, family Real sawflies).
Distributed in all regions of Russia. Damages gooseberries, red and white currants. The adult is 6-8 mm long, with two pairs of wings, the female has a yellow abdomen and legs, the male is black, the breast and lower abdomen are yellow. False caterpillar up to 17 mm long, grayish-green, with a black head, 20-legged. The larvae hibernate in a cocoon at the base of the bush in the soil at a depth of up to 15 cm. Departure from wintering sites coincides in time with the deployment of the first leaf on the gooseberry and continues until the beginning of flowering. The female of this pest of currants and gooseberries lays elongated-oval eggs in a chain along large veins on the underside of the leaf. Fertility is about 150 eggs. The hatched larvae skeletonize leaves and gnaw them perforatedly. Middle and older larvae roughly eat leaves, leaving only thick veins. It develops 1-3 generations per season.
Protection measures: late autumn tillage between rows and under bushes mulching with peat.To treat gooseberries and currants from these pests, spraying is carried out with approved preparations (altyn, danadim, lepidocid, sensei, lambda-C, spark, etc.).
Currant gall midge - Dasyneura tetensi (order Diptera, family Gall midges). Damages black currant, especially harmful when growing planting material in nurseries. The adult insect is about 1.5 mm long, with one pair of membranous wings, long legs and 16-segmented antennae, the body is brownish-orange in the female with a long pointed ovipositor. Larva 2-2.5 mm long, legless, white or yellowish. Adult larvae overwinter in white cocoons in the upper (up to 5 cm) layer of soil under currant bushes. During the budding period, the larvae pupate. The flight of gall midges coincides with the beginning of flowering of black currants. Females lay 30-100 eggs, placing them in groups in young, undeveloped leaves. Without proper processing of currants and gooseberries, this pest gives 3-4 generations during the growing season. The gall midges of the second and third generations cause the greatest harm. Damages black currant, especially harmful when growing planting material in nurseries. Young leaves, if there are many larvae in them, stop growing and dry up before they have time to unfold. Unfolded damaged leaves of an ugly wrinkled shape, with tissue breaks between the veins.
Protection measures: late autumn and early spring soil digging under currant bushes; soil mulching under bushes (by 6-8 cm); spatial isolation of nurseries from industrial plantings. To combat these pests of currants and gooseberries, treatment with preparations of fufanon expert, danadim, bitoxibacillin is recommended.
Currant kidney mite - Cecidophyopsis ribis (order Acariform ticks, family Eriophiids). Damages black currants, also occurs on white and red currants and gooseberries.
Look at the photo - the body of the female of this pest of currants and gooseberries is worm-shaped, has a length of 0.2-0.22 mm of 2 pairs of legs:
Females hibernate inside the buds. Each of them can contain up to several thousand individuals. In spring, the inhabited buds are distinguished by their large size and swollen-rounded shape. Badly damaged kidneys die off. Females lay up to 100 eggs inside the kidneys. Before flowering, these pests of currants and gooseberries begin to migrate to the leaves, and then penetrate into the young developing axillary buds. They can be carried around the plantation by wind, insects and other animals, as well as on the tools and tools of working people. During the season, it develops up to 4-5 generations. Damaged kidneys swell gall-like and dry out. The tick is the main carrier of the dangerous viral disease of currants - terry, or reversion.
Protection measures: the use of healthy planting material of resistant varieties, which is obtained by propagating plants by tissue culture or using cuttings thermotherapy. To treat gooseberries from diseases and pests during thermotherapy, cuttings are heated in water at a temperature of 45-46 ° C for 13-15 minutes before rooting. Spatial isolation of mothers and nurseries from industrial plantations and personal subsidiary plots. To treat currants and gooseberries from these pests, as well as from many other diseases during the migration of ticks, the bushes are sprayed with aliot or acarin. In small areas, plucking and destruction of damaged kidneys are carried out.
The final section of the article describes how currants and gooseberries can be processed to protect against diseases and pests.
Spring pest control of the garden includes the use of effective chemicals.
Table "Chemical preparations for processing plants in the garden and in the garden in early spring":
It was created in America more than 70 years ago and has been used in our country for over 60 years, so that almost all pests have long been adapted to it, and therefore treatments with this drug are practically harmless for them.
Inta-vir, Decis, Karate, Fury
They belong to the same group. They are highly toxic, therefore very effective, but at the same time they kill beneficial insects, bees and earthworms, since they take about three weeks to decompose, and during this time beneficial insects will come out of their shelters and die from the effects of pesticide residues. And they cannot be used at all from the moment of flowering, not only of the garden, but also of the mother-and-stepmother, since at this time bumblebees appear and worms crawl out
They decompose quickly, within 5-7 days, even before the appearance of beneficial insects, but they are less effective, therefore, with a large number of pests, it is pointless to use them, and with a small number of pests, chemical treatment can be completely dispensed with. In addition, they pollute the environment ten times more.
All of these drugs kill pests, getting into their intestines along with food and causing poisoning. Therefore, there is no point in using them to spray egg-laying or pest pupae.
The chemical poisons listed above can only be applied in the garden before flowering! But at the same time you destroy not only pests, but also your own liver.
Use biological products Iskra-bio (formerly called Agrovertin) or Fitoverm, they are obtained from soil bacteria and micro-fungi, and therefore are not pesticides.
Never spray in windy conditions as there are early green crops already at this time. When treating the garden with non-biological preparations, they must be covered with a film, otherwise you can poison yourself.
Instead of these chemicals, you can use the same mineral fertilizers that are listed above, but only their concentration should be 7-10 times lower, otherwise you can cause a severe burn of the opening buds and buds. It is possible to recommend spraying on a green cone with a 0.7% urea solution - dissolve 70 g (3 tablespoons) of urea in 10 liters of water. But this is in case you do not have Fitoverm or Spark-bio at hand.
