The gooseberry has small leaves and berries. The main gooseberry diseases: how to define them and how to fight

Gooseberry - make a diagnosis

Gooseberries can infect both diseases and some pests. It is important to control its condition and react in a timely manner, otherwise you may not get a harvest and even lose a bush. It is worth noting that all diseases affecting gooseberries are fungal. That is, they spread quickly.

Onion diseases and treatment

Consider the main diseases and their features:

There are no less pests infecting gooseberries than fungal diseases. Let's consider some of them:

A stock of insecticides and a good sprayer should always be at the ready if you want to taste compote or gooseberry jam in the fall.

Gooseberry diseases and their treatment

After such an abundance of "diagnoses", the gardener may want to get rid of the problem plant altogether. Everything is not so scary if you know the main gooseberry diseases and measures to combat them. When a gooseberry is exposed to powdery mildew disease, many people lose heart. The fight against this defeat is often unsuccessful, but quite real.

All gooseberry diseases and their treatment are approximately the same. The main rule that applies to all types of infections is the urgent pruning of branches affected by the fungus. The branches must be burned immediately.

It is not bad to dilute useful microflora - bacteria that process organic matter - to fight the fungus. They are found in abundance in any organic fertilizer, which should be diluted with water (1 in 10), filtered and sprayed with the resulting liquid. Bacteria, multiplying, will feed on fungi, thereby destroying them. In addition, it is also a good feeding of the bushes. However, this is more a preventive way than the ability to quickly cope with diseases.

You can also spray the entire plant and the soil under it with a solution of ferrous sulfate - the drug is well known as a fungicide. However, today there are many more effective (and expensive, by the way) means for spraying. Processing is necessary every 10 days in dry weather.

The fight against insects that infect gooseberry bushes also begins with the removal of all affected parts. Bushes must be processed before and after flowering. It is important to dig up the soil and huddle bushes. After reading the article, it is advisable to consider gooseberry diseases in pictures. This will help you quickly navigate at the first signs of a problem and recognize the "enemy in the face".

Gooseberry: diseases and their treatment

On the territory of our country, gooseberries are quite popular. Diseases, unfortunately, do not bypass him, and in order to get good harvest, you need to take care of the elimination of this scourge.

The main types of diseases

All diseases of these garden bushes can be conditionally divided into two types: verticillary drying and wilting of branches and shoots and a variety of spots. Let's consider them in more detail.

How verticillus wilt and desiccation of gooseberries are affected? Diseases of this kind affect the branches and leaves of bushes. In the first case, wilting of foliage is observed, which at the same time acquires a yellow color. It does not crumble from the branches, but remains attached to them. The second name for gooseberry disease speaks for itself. The branches and shoots of the bushes dry out, cracks appear on the bark, between which black dots are clearly visible - the causative agents of the disease.

As already mentioned, a variety of gooseberry spots are also affected. Diseases of this type can belong to one of five types of pathogens:

1. Black spot, or alternaria - gray-black spots appear on the leaves of the bushes with a velvety coating of olive color of a relatively large size.

2. Brown spot - the appearance on the leaves of brown spots with a small black bloom.

3. Ascochitous spotting - spots of light gray or white, around each of which there is a brown border, rounded, sometimes with black dotted pycnidia.

4. White spot (septoria) - the appearance of small angular or rounded brown spots on the foliage of shrubs, around which there is a red-brown border. Over time, these spots become lighter, but the border remains the same bright.

5. Anthracnose spot - may appear not only on foliage, but also on branches and petioles. It is a small, depressed, rounded spots of dark brown color.

Some more points should be covered regarding the spots that gooseberries suffer from. Diseases of this kind have characteristic features: spots, sporulation and pads. All of them are located on the top of the leaves. However, if light spots are visible from above, and there are orange sporulation pads below, then this is already rust. And it spreads quite interestingly.

Other diseases

If sedge grows next to the bushes, gooseberry rust may appear on the gooseberry, if Siberian cedar or Weymouth pine, then columnar rust. Thanks to this neighborhood, the causative agent of the disease has the opportunity to overwinter on sedge or pine, and in the spring to infect young gooseberry leaves.

Sometimes a thin black film can be seen on the gooseberry; this is nothing more than a disease called mob. Another ailment is also known - spheroteka, also called powdery mildew. It is a bloom on gooseberries. If the plant is severely affected by this disease, then on young shoots in the upper part, drying occurs, but the pathogen overwinters under the bark.

All the diseases that were listed above belong to the fungal category, but viral diseases are also found in shrubs. These include the edging of the veins. The plant has a pale yellow border on the first and second order of veins. Plus, chlorosis occurs on the leaves, after which they quickly lose their shape and become wrinkled.

Fighting disease

There are not so many drugs used to fight various gooseberry diseases. This is copper sulfate, which helps to get rid of septoria and other types of spotting, cumulus saves from powdery mildew, anthracnose and ascochitosis, as well as Bordeaux mixture - from rust, septoria and anthracnose.

Some gardeners are trying to use drugs such as Topaz and Fundazol to fight gooseberry diseases. This decision is incorrect, since these funds can only be used to treat black currant. However, if there is a whole gooseberry nursery on the site, then it is possible to use Fundazol in order to get rid of verticillary wilting of gooseberry bushes.

Powdery mildew on gooseberries - prevention and measures to combat it and other diseases

Anthracnose

One of the dangerous fungal infections. Their first signs can be seen on the green parts of the gooseberry - foliage, young shoots and even on the stalks. At first, they are just single brown specks that grow and enlarge, spreading the infection. Leaves fall on a sick plant, its development stops and their berries cannot be expected.

Like all fungal diseases, anthracnose spores are activated in raw weather conditionsafter a long rainy season or cold fog. If the sites are located in lowlands or the soil is heavy, with frequent stagnation of water, the likelihood of outbreaks is high.

As preventive measures, soil digging and treatment with appropriate preparations are used. On the first warm spring days, the plot of land around the gooseberry needs not only to be loosened, but to be dug up, turning over the clods of soil. This is done in order to enrich the soil with oxygen and prevent the spread of pathogens. After that, it is recommended to sprinkle the bushes. Most familiar, but no less effective drug - copper or iron vitriol, used according to the instructions. The degree of their sprinkling should be such that falling drops not only cover all branches, but also flow freely to the ground around. An analogous effect is given by a solution of Bordeaux liquid, prepared at the rate of 100 g of the drug per 10 liters of water.

The first procedure must be carried out before bud break, and given the fact that gooseberries are very early in this regard, it is important not to miss the moment!

Opponents of the use of "chemistry" can replace drugs with organic solutions: a third of a bucket of fresh manure, mullein or bird droppings pour water and let it brew for 2-3 days. After that, the infusion is filtered, diluted with water three times and used for spraying.

Two weeks later, the second procedure is carried out, and after a while, if necessary, the next one. And only a month before the ripening of the berries, the spraying is stopped, resuming them after the harvest.

Spheroteka

Another name for this gooseberry disease is American powdery mildew. Signs of infection are a whitish bloom that appears after the flowering period. Later, the gray spots become denser and acquire a brownish tint. Due to the disease, the plant slows down all development processes, their shoots weaken and deform, the leaves wither, and the formed ovaries fall off.

The most effective prevention of powdery mildew is considered to be the cultivation of certain varieties that are sufficiently resistant to fungal infections. Among gardeners and gardeners, the cultures of our selection are deservedly popular: Rodnik, Russian, Lada, Pink 2 and others, and from foreign ones - Pearl, Jocelyn, Houghton. You can improve the immunity of a plant by planting it in sunny, well-ventilated places, as well as applying fertilizers containing phosphorus and potassium.

On the other hand, excessive spring pruning and frequent nitrogen fertilization can make the plant's defenses weaken and difficult to resist disease.

Prevention of powdery mildew is similar to the prevention of anthracnose - spring digging and spraying. When processing young shoots good results gives a preparation prepared as follows: a 3-liter container is filled with charcoal and ash, water is added, brought to a boil and "boiled" for about half an hour. To the resulting solution add about 40-50 g of chopped laundry soap, stir, cool and use for spraying. And of the ready and safest fungicides, which are used to treat powdery mildew and other fungal infections, Fitosporin is considered.

Gray rot

It is found on many popular berry crops - strawberries, wild strawberries, but sometimes gooseberries are also affected. Although gray rot is not considered as dangerous as the diseases mentioned above, the damage from it is tangible. It is not difficult to determine the signs of infection - a gray bloom on the fruits and their inevitable loss. Berries on the affected plants rot and crumble.

To combat gray rot, it is enough to collect and destroy the affected leaves and fruits, and thin the bush for better ventilation. It will not be superfluous to pour a handful or two of charcoal under the bush.

Goblet rust and columnar rust

It can be diagnosed by noticing the appearance of yellowish tubercles on the underside of the leaves, as well as on the buds, flowers and ovaries. After a while, they turn into a kind of "felt" bloom, the plant weakens, the quality and quantity of the crop falls. The reason for the appearance of goblet rust is considered to be the unfavorable neighborhood of gooseberries with sedge or cedar plantings. From this we can conclude that timely mowing of sedge or, in the case of cedars, transplanting the bush to a new place will be effective prevention. Infection with columnar rust can occur if the site is located next to a pine forest, based on this, preventive measures for the disease become obvious.

In addition to radical measures with transplantation, treatment and prevention can include the traditional spring digging of the soil around the plant and spraying them with antifungal drugs (Fitosporin, Bordeaux liquid, and others).

Septoria (white spot)

Symptoms of the disease are brown spots, which later become whitish with a brown border around the edges. Usually they can be seen on leaves, but sometimes fruits are also affected.

Effective protection for gooseberries is the same as for powdery mildew - treating the bush before budding with a solution copper sulfate or a nitrofen preparation. After a while, spraying can be repeated using Bordeaux liquid at a concentration of 100 g per 8-10 liters of water.

General rules for dealing with any fungal disease necessarily include:

cutting of infected, diseased branches with subsequent burning;
mandatory cleaning of leaves and fruits that have fallen after a disease, which must also be immediately destroyed (especially if powdery mildew is diagnosed);

preventing stagnation of moisture under the bush (planting on a hill, arranging drainage, improving clay soils by adding sand and peat)
annual rejuvenating pruning, which contributes to better lighting and ventilation of the bushes.

Gooseberry diseases

Growing gooseberries in your own summer cottage is fraught with many difficulties. Gooseberries require effective preventive measures against diseases.

What is gooseberry sick with?

Gooseberries suffer from the same diseases that currants are prone to. The only difference is in the degree of damage and the rate of spread of the disease. In gooseberries, diseases are more intense, spread faster. Gooseberry diseases can lead to very disastrous results - loss of yield or complete death of shrubs.

That is why you need to know what are gooseberry pestsand what measures will be effective to remove or exclude pests from the site? If gooseberry diseases are localized in a small space, then they can be eliminated with the help of herbal preparations. If the affected area is extensive, you will have to resort to the use of fungicides.

Powdery mildew

One of the most common gooseberry diseases is called powdery mildew or spheroteka. This disease manifests itself after gooseberry flowering. Powdery mildew is represented by a white bloom, localized on the leaves, ovaries and twigs of a gooseberry bush. Plaque looks like a whitish spider web or fine powder.

Gradually, the plaque becomes brown, denser and thicker. In shoots affected by powdery mildew, growth stops, blackening and gradual drying are observed. The yield of gooseberry bushes affected by powdery mildew is significantly reduced, gooseberry berries fall off before reaching full ripeness.

Powdery mildew often affects gooseberries with high soil moisture, heavily thickened plantings or rainy weather. During hot and sultry weather, the activity of powdery mildew decreases, but the pathogen can exist on gooseberry bushes, wintering on affected fallen berries or on gooseberry branches. Re-infection occurs with the onset of spring.

Gooseberry diseases and their treatment need to be identified and warned in time. If powdery mildew has spread over the site, it is necessary to spray the bushes with iron vitriol or infusion of fresh mullein. The spraying procedure is best done before the first buds appear in the spring. Gooseberry branches and berries affected by white bloom are cut off and removed from the site completely. Gardeners recommend growing thornless gooseberries, which are not prone to powdery mildew.

Anthracnose

Gooseberry diseases are also represented by anthracnose. This disease mainly affects the leaves. First, brown spots with shiny dots in the center appear on the leaves of the gooseberry, then these spots merge, the leaf becomes completely brown and falls off ahead of time. Gooseberry anthracnose leads to a decrease in the yield of berries, young shoots stop forming and developing, the berries lose their sweetness.

The causative agent of anthracnose hibernates in plant debris, and with the onset of spring it re-infects gooseberry bushes. Anthracnose is actively distributed during the rainy season in spring and summer. All leaves, fruits and branches of gooseberries affected by anthracnose must be removed from the site in a timely manner, gooseberry bushes are sprayed with Bordeaux liquid or copper sulfate to prevent anthracnose.

White spot (septoria)

Gooseberry pests can lead to the development of white spot (septoria) on gooseberry leaves. This disease begins to affect the leaves, forming grayish spots on them, with a dark edging. Gradually, dark dots form on the spots - spores of septoria, gooseberry leaves dry out and fall off under the influence of the causative agent of septoria, and the bushes of the garden culture remain bare.

The septoria pathogen transfers wintering on fallen leaves of the gooseberry, therefore, in the fall, they must be removed from the site. For spraying gooseberry bushes with septoria, copper oxychloride or copper sulfate is used.

In the summer, when signs of septoria on the gooseberry appear, they are sprayed with Bordeaux liquid. Preventive measures to prevent septoria disease are fertilized soil under the gooseberry with zinc, manganese sulfate, boron, copper and complex mineral fertilizers.

Diseases of the gooseberry and their treatment are important to detect in time, to eliminate the sources of spread of the pathogen from the site (as a rule, these are branches, leaves, berries of gooseberries or currants). For prevention, you need to regularly spray gooseberry bushes with Bordeaux liquid, copper sulfate. Gooseberry bushes need to be fed with mineral fertilizers. Prevention of gooseberry diseases is the most effective way to protect your garden from pests, to preserve the gooseberry harvest.

And finally, we recall: if you choose the right siderates that repel pests of garden plants, including gooseberries, you can protect your garden from a large number of pests. It seems that everyone knows about such wonderful properties of green manure, but they rarely use them. Igor Serba, member of the editorial board Sobkor of the Internet edition "AtmAgro.

Fungal diseases of gooseberries and currants - treatment and prevention

Fungal diseases of gooseberries and currants, unfortunately, are very common on summer cottages... Particularly dangerous is Spheroteka or powdery mildew, which affects the entire plant - leaves, flowers, fruits. Anthractosis - damage to the leaves, red spots appear on them, the leaves dry out, fall off and, ultimately, the whole plant suffers - the crop dies.

Powdery mildew on currants and gooseberries. How to save shrubs?

Sad.usadbaonline.ru

American powdery mildew, or spheroteka (gooseberry).

A fungal disease that affects all parts of gooseberries and currants: leaves, ovaries, berries and young shoots. The disease appears in early or mid-summer.

The affected parts of the plant are covered with a white, mealy, easily washable bloom, which gradually thickens and becomes like a dark brown felt.

Diseased shoots are bent, dry up and die off, the apical leaves curl.

The fruits are not poured, they become practically inedible and fall prematurely.

If severely affected by powdery mildew, plants can die within two to three years.

The disease is caused by a fungus that hibernates on affected shoots and fallen diseased berries. The mycelium is located on the surface of the plants and is attached to them with special suction cups.

In the spring, spores are thrown out of the bags and infect the plants. The most favorable conditions for the development of the disease are thickened planting, shaded areas, and high soil moisture. On the contrary, hot and dry weather inhibits the development of the disease.

Control measures

Planting varieties that are resistant to American powdery mildew. Sphero-resistant gooseberry varieties include Izumrud, Mysovskiy 7, Mysovskiy 37, Malachite, Pyatiletka, Smena, Solnechny, Sibiryak, Black negus, Schedry, etc.

Collection and cutting of the affected tops with leaves, shoots and berries and their destruction, that is, reducing the sources of secondary infection in summer and primary infection in autumn.

To eradicate the infection, spray the bushes and the soil under them with iron sulfate (300 g per 10 liters of water). During the growing season, at the first signs of the disease, the bushes can be sprayed with soda ash (linen) soda (50 g of soda per 10 l of water) with the addition of 40-50 g of soap to the solution for adhesion, repeating the treatment 2-3 times after 8-10 days. It is effective to use fresh bleach (1-2 tablespoons per 10 liters of water) to combat spheroteka.

Treatment of bushes with any of the solutions should be started when a white powdery bloom appears on young leaves or berries and repeated after 10 days. If it rains earlier than 5 hours after treatment, repeat the spraying. It is necessary to finish processing the bushes with a solution 2 weeks before picking berries.

On currants, it is allowed to use before flowering and after harvesting sulfur preparations (40-60 g), foundationol (10 g) and 10% emulsion of Topaz preparation (2 g per 10 l of water).

The bacterial method gives good results. To do this, use an infusion of mullein or rotted manure (for 1 part 3 parts of water, leave for 3 days, then dilute three times with water and strain). In the same concentration, you can prepare an infusion from rotted hay, hay dust, greenhouse soil or forest litter.

The destructive effect of these infusions on the powdery mildew fungus is explained by the fact that bacteria multiply in them, which, falling on the bushes of plants affected by the spheroteka, begin to feed on the fungus, destroying it.

It is enough to process bushes with infusions 3 times: the first time before flowering, the second - after flowering and the third - before leaf fall. Spraying is carried out in the evening or in cloudy weather during the day.

Sometimes it is very offensive and unpleasant when powdery mildew affects the gooseberry. A white bloom begins to appear on the plant, as if sprinkled with chalk or flour. Most gardeners in this situation cut and discard the affected bushes. But the plant can still be saved. This requires:
- Make an infusion: chopped tops of tomatoes (one kilogram) and one quarter of a chopped piece of laundry soap, pour a bucket of water. After a day, spray the gooseberry bush with the resulting infusion.
- In order for the next year not to have the same problem, it is necessary, during the preparation of the garden for wintering, to overlay the gooseberry bush with dry tomato tops. The substances that the tops release will permanently destroy the powdery mildew fungus.

Gooseberry anthracnose

Fungal disease of currants and gooseberries that affects the leaves. Small, vague, irregular dark brown spots are formed on them.

With a strong development of the disease, the spots merge, the leaves turn brown, dry out, their plates curl upside down.

They fall off prematurely and remain only at the ends of the growing shoots. In diseased bushes, the growth of young shoots is greatly reduced, the yield and sugar content of berries are sharply reduced.

Control measures for currant and gooseberry disease:

In gardens infected with anthracnose, the bushes and soil are generously sprayed with nitrafen or copper sulfate. Spraying is carried out before bud break in early spring.

If necessary, to combat the anthracnose of currants and gooseberries, Bordeaux liquid (100 g per 10 l of water) or captan, chomycin, cuprozan, phthalan, colloidal sulfur can be used by spraying or when the first symptoms of septoria or anthracnose appear.

The second spraying is carried out 10 days after harvesting.

Spraying is carried out in compliance with all the rules.

It is necessary to remove all the fallen leaves under the currant and gooseberry bushes (this is where the spores of the fungus winter) and dig up the soil in the near-stem circle (late autumn or early spring).

Septoria spreads especially strongly with thickened plantings.

It is necessary to prevent the spread of weeds on the site.

Cause of the disease: fungal disease. The causative agent of gooseberry and currant anthracnose overwinters on fallen leaves.

Anthracnose is spread by conidia in summer.

Many gardeners grow gooseberries. Its yield largely depends on proper care and control of diseases and pests. Let's consider the main diseases of gooseberry in pictures for greater clarity and measures to combat them.

Spheroteka or American powdery mildew is one of the most common fungal diseases of gooseberries.

It is expressed in the appearance of a characteristic spiderweb bloom after flowering. Over time, the plaque begins to turn gray, thicken and turn brown. As a result, the shoots stop developing, change in color and deform, the berries fall off in a green state. This disease should be feared during prolonged rainy but warm weather.

Measures to combat spherotek

It is best to grow gooseberry varieties that are resistant to spheroteca: North American gooseberry varieties - Houghton, Pearl, Jocelyn, Curry; from domestic - hybrids Russian, Plum, Pink-2, Rodnik, Sadko, Lada, Pushkinskiy and others. Fertilize gooseberries with phosphate-potassium fertilizers to increase spherotec resistance. But an excess of nitrogen fertilizers and super-strong pruning of plant bushes will reduce resistance to disease. Plant gooseberries in a ventilated area.

Dig up and mulch the soil in the spring. When the buds have not yet blossomed, spray the gooseberry bushes with a solution of copper sulfate (50-100 g of the drug per bucket of water) or ferrous sulfate (300 g per bucket of water). If fungicides are not used, then you can spray with mullein infusion (a third of a bucket of fresh mullein is kept for three days, filtered and diluted with water 1: 3). Spraying should be carried out on the same day. Re-processing is carried out after 10-14 days. After harvest processing can be done again.

If the spheroteka struck young shoots, then they need to be treated with this mixture: add water to a third of a bucket of wood ash and boil for 30 minutes, add 40 g of laundry soap, cool. After flowering, spray with a solution of soda ash (30-50 g of soda and soap per bucket of water). Repeat spraying after 10 days.

In the fall, inspect the gooseberry bushes; if there are traces of disease damage, then remove such shoots. Destroy fallen leaves and berries, dig up the soil under the bushes.

From biofungicides, Fitosporin can be used.

Anthracnose - no less dangerous fungal disease gooseberry. It manifests itself in the appearance of brownish spots on the leaves, shoots and stalks, growing and merging into one large spot, after which the leaves fall off, the development of the plant stops and, as a result, the yield decreases. Prolonged rains and dampness contribute to the appearance of the disease.

Gooseberry anthracnose control measures are similar to the fight against spherotek.

In early spring and autumn, they dig up the soil under the bushes. Perform anti-aging pruning. Remove weeds from the site.

Before bud break, spray the bushes and soil with nitrafen or copper sulfate. At the first symptoms of the disease, you can spray with Bordeaux liquid (100 g per bucket of water) or colloidal sulfur. 3-4 weeks before harvesting, all treatments are stopped. 10 days after harvest, another spraying is carried out.

Gray rotaffects the lower part of the gooseberry shoots and causes rotting of the berries, which fall off with a continuous defeat. The disease is not particularly dangerous and is not typical for gooseberries.

Measures to combat gooseberry gray molddo not cause special difficulties. It is enough to collect and destroy the affected berries, remove damaged shoots and thin the bushes for better illumination and ventilation.

Gooseberry septoria or white leaf spot manifests itself in the appearance brown spots, later they turn white and the brown color is accompanied in the form of a border. Spots appear on the leaves and sometimes on the berries.

Measures to combat gooseberry septoria:

Abundant spraying with nitrafen or copper sulfate before bud break. Can be sprayed with Bordeaux liquid (100 g of preparation per bucket of water). Spraying is repeated 10 days after harvest. Collect all fallen leaves under the gooseberry bushes and destroy, preferably not on the site. The soil is dug up in early spring and autumn. Watch for the appearance of weeds, remove them in a timely manner.

In this case, Bordeaux liquid can be replaced with Captan, Ftalan, Tsineb

Goblet and columnar rust

These diseases of the gooseberry are characterized by the appearance of yellow pads on the underside of the leaves, ovaries and flowers (on the left - goblet, on the right - columnar). Towards autumn, the lower part of the leaf is covered with brown “felt”. If you grow gooseberry bushes in a lowland where there is sedge or a cedar or pine tree grows on the site, then your gooseberry is more likely to get sick with goblet rust.

Control measures for gooseberry disease Primarily reduced to mowing sedge meadows near your site, up to 200 meters, since the development of goblet rust is associated with sedge, and columnar develops on pines and cedar. Collect and burn leaves under bushes, loosen the soil.

Treat the gooseberry bushes with a solution of 1% Bordeaux mixture during the opening of the leaves, then with the separation of the buds and after flowering. If the disease is severe, then another spraying is carried out 10 days after the third. You can use the biofungicide Fitosporin.

Dry gooseberry

The bark of gooseberry twigs cracks and dries up. In the cracks, over time, stromas of the fungus appear in the form of tubercles, where spores develop. The disease mostly affects weak gooseberry bushes.

As a fight against fungal disease by drying out it is enough to follow the basic measures for caring for gooseberries, disinfect the instrument when cutting it and process the cut sites with a solution of Bordeaux liquid (100 g per bucket of water) or garden pitch.

Gooseberry mosaic

Yellow stripes appear along the veins of the leaves, over time, the leaves begin to shrink and shrink, the yield decreases.

Control measures for gooseberry mosaic:

Like any viral disease, it is almost impossible to cure, therefore, it is necessary to fight against viruses radically, uprooting the plants and then burning them. As a prophylaxis for the cultivation of gooseberries, only healthy planting material is used and timely processing of the bushes against sucking insects (aphids, plant mites - carriers of viruses) is carried out. Disinfection of the instrument is also important when.

The most common drugs to fight gooseberry diseases are Copper Sulphate against all kinds of spots, including anthracnose, Cumulus against powdery mildew, anthracnose and ascochitosis, and Bordeaux liquid against anthracnose, rust and septoria.

Fruit Disease: Bitter Pitting and Control Measures

Gooseberry pests and diseases

Gooseberry shoot aphid - affects all types of currants and gooseberries. In autumn, she lays eggs on shoots near the buds. In May, when the buds begin to swell, larvae emerge from the eggs, they move to leaves and young shoots, sucking the juice out of them. Affected leaves curl, dry out and fall off. Shoots do not grow. The damaged leaf, growing, more and more shows dark red swellings.

Control measures: in early spring, to destroy eggs, the bushes should be sprayed with nitrafen or copper sulfate (200-300 g per 10 l of water), or after flowering they are sprayed with Fitoverm (this is a natural preparation): 10 ml of the preparation is diluted in 5 l of water. Sprayed during the day at a temperature of at least 15 degrees. The aphids that appear are destroyed by infusion of garlic, makhorka, pharmacy chamomile.

Spider mite - damages gooseberry leaves. Affected leaves turn brown, their edges curl up and dry out. Tick \u200b\u200bfemales hibernate under dry leaves, plant debris, in clumps of earth, and garbage. In spring, multiplying, they settle on the underside of the leaves, suck the juice out of them. Autumn digging of soil under bushes, spraying with karbofos (20-30 g per 10 l of water) during bud break before flowering and immediately after flowering prevents the appearance of pests. Also, after flowering, when ticks appear, they are sprayed with a highly effective preparation "Fitoverm" (10 ml of the preparation is diluted in 5 liters of water), and after the last collection of berries, they are sprayed with the preparation "Fosbecid" (5 ml of the preparation are diluted in 10 liters of water). You can spray the plants with a stream of water that knocks the mites off the underside of the leaf. This method is simple and accessible to everyone.

Gooseberry moth - in spring, when the temperature reaches 13-15ºC, a small gray butterfly flies out of wintering grounds. The female lays eggs inside the flower, caterpillars appear in a week. They bite into the ovary, eat the seeds. Damaged berries turn red, spoil and crumble long before ripening. Caterpillars crawl from one berry to another, then descend to the ground and go into the soil, where they pupate.

The appearance of these pests is prevented by the autumn digging of soil under the bushes with a turnover of the layer. Frequent loosening of the soil before the caterpillar descends to the ground can also help control pests. You can spud the bush by 10-12 cm so that the butterfly cannot fly out in spring. Before flowering and after flowering, plants are treated with green ovaries with the preparation "Inta-Vir" (1 tablet is diluted in 10 liters of water). Or use the drug "Fitoverm" (for 3 liters of water, dilute 5 ml of the drug). Fosbecite is also suitable (diluted with 5 ml of the drug in 5 liters of water). Collecting and destroying the affected berries helps the fight against moths until the pest leaves them.

Gooseberry sawfly - completely eats away the pulp of the leaves, leaving only the net. To prevent this from happening, you need to monitor the condition of the plant. As soon as you find damage, immediately spray the bush with a solution of karbofos (20-30 g per 1 liter of water) or the preparation "Phosbecid" (10 ml of the preparation is diluted in 10 liters of water), stir well and spray. Solution consumption for one bush is 1.5-2 liters.

Powdery mildew (spheroteka). It affects gooseberries and black currants. Fungal disease. It appears as a white powdery bloom on young leaves, green shoots and berries. Then the plaque gradually turns brown. This usually happens when the berries are being poured, which crack and, shrinking, fall off. Shoots stop growing, turn black and dry out. The plant weakens, becomes stunted, does not bear fruit. White bloom is a mycelium that forms many spores. They are carried by the wind, infecting other plants. Spores overwinter on branches, leaves, unharvested berries. Dampness favors the development of the disease.

Control measures: primarily in the selection of varieties. It is necessary to select such gooseberry varieties that would be resistant to this disease. In early spring, to prevent the appearance of powdery mildew, you can spray the bushes with a solution of nitrophene or copper sulfate. You can also use the drug "Topaz" (1 ampoule is diluted in 10 liters of water), or 2 tablets of the drug "Oxyhom" are diluted into 10 liters of water, this treatment is carried out after the last harvest. Affected leaves and shoots must be carefully removed and burned. Good preventive results are obtained by the introduction of phosphorus-potassium fertilizers in the form of top dressing in the second half of the summer.

Anthracnose is a fungal disease. It affects the leaves of gooseberries and currants, causing their premature death. Signs of the disease: very small, lacquered brown tubercles appear on the leaves. With a strong defeat, they merge, the leaves dry up and fall off. The disease can also affect leaf stalks, stalks, green shoots. The development of the disease intensifies in the second half of summer, when damp weather sets in. The fungus hibernates on the affected leaves, and forms spores on them, which infect the plant.

Spraying with a solution of Bordeaux liquid helps to get rid of this disease. The first spraying is done immediately after flowering, the next two - at intervals of 10 days. Before swelling of the kidneys, nitrophene solution (200 g per 10 liters of water) can be used. With anthracnose infestation, harvesting and burning of the leaves is imperative.

Rust is a fungal disease. Gooseberries and currants are affected by two types of rust - goblet and columnar. The first is more striking. Orange pads appear on the leaves and fruits of plants.

Control measures: in the spring before flowering, the bushes are treated with a green leaf with the preparation "Hom". For 10 liters of water, dilute 40 g of the drug, stir thoroughly and spray. Also in 10 liters of water dilute 10 g of the drug "Fundazol", sprayed immediately after flowering on green berries.

Terry is the most dangerous disease of black currant. This is a viral disease that is transmitted to the plant from the plant with the help of sucking pests, the disease is also spread by kidney mites. Signs of the disease: flowers change, they become terry - cups, corollas, stamens turn into small purple petals. Sometimes the flower brush is sprinkled with scales, there are no flowers and berries.

Control measures: plants are dug up and burned. They plant healthy seedlings and constantly fight against pests that are carriers of this disease.

Speaking about pests and diseases of berry trees, it is worth warning novice gardeners: in those areas and bushes where there were many pests, they should be expected to appear next year. Here you should carefully follow the requirements of agricultural technology and take timely measures to protect plants.

The worst enemy of fruit bushes is defeat by various types of fungal infection. The most dangerous are powdery mildew, rust, anthracnose, mycoplasma disease terry. The topic: "Gooseberries: diseases and their treatment" is very relevant.

If the pest control is lost, you will lose crops in the current season, and in the long term, adult fruit plants. Therefore, it is very important to know the diseases of the gooseberry, the treatment of these diseases, the drugs for treatment.

Powdery mildew on fruit plantations

Currants and gooseberries (diseases and their treatment are described below) are often affected by powdery mildew.

Spheroteka (also called powdery mildew) is the most serious disease for gooseberry and currant shrubs. Gooseberries are in greatest danger. The incidence of black and red currants is generally lower, but prevention is needed.

Pest: powdery mildew mushroom. In spring, spores settle and new shrubs are infested. In summer, the fungus forms conidia on the surface of the plant for more than 10 generations, fruiting bodies ripen in late autumn and winter on the affected shoots and berries.

Signs of the disease

It is very important to know the symptoms of gooseberry disease and their treatment. The fungus affects all parts of the plant: new shoots, young leaves, buds, fruits. Externally, a whitish bloom can be seen on the plant, which becomes denser over time and acquires a brown tint. External deformation of shoots, leaves, fruits occurs. The plant dries up, despite the sufficient moisture in the soil, and if inactive, it can die in the next 2-3 seasons. Fruits do not develop or become unfit for food.

Control measures

Currants and gooseberries (diseases and their treatment are described in this article) require the following measures:

Choose varieties of gooseberries and black currants that are resistant to powdery mildew.
Destroy diseased shrubs, do not take young shoots from them, since infection occurs at a rapid pace.
To minimize the use of fertilizers with a nitrogen component, more phosphorus fertilizers - their use reduces the incidence of the disease.
At the first sign of powdery mildew, do not postpone preventive measures.

Gooseberry: diseases and their treatment folk remedies and "chemistry":

Copper sulfate. Shrubs of currants and gooseberries can be processed already during the blooming and flowering period, when the leaves have not yet begun to actively bloom. If there is little time, processing can be carried out at the time of active budding. From the period of the first treatment, count 8-15 days and repeat again, if necessary, the procedure can be repeated again. All manipulations are completed 15-20 days before eating the berries. The concentration of the preparation for crystalline copper sulfate is about 300 g per bucket of water with a volume of at least 10 liters, it is advisable to process not only the plant, but also the soil under it. If it rains in your area before the expiration of 5 hours, you should repeat the treatment when clear weather is established.
Wood ash and coal. The mixture is prepared at the rate of 3 kg per 10 liter bucket. The powder is diluted in boiling water, the mixture is filtered, the bushes are treated with the resulting composition every 10 days.
Linen soda and laundry soap. Measure 50 g of linen soda, add the same amount of shavings of laundry soap, dissolve in a 10-liter bucket of water, soap is used to increase the stickiness when applying the composition. The treatment must be repeated systematically, every 10 days, and stopped two weeks before the berry harvest.
Bleaching powder. A well-known drug that has shown excellent effectiveness. The dosage is 2 tablespoons of crushed powder per 10 liters pure water.
Compositions containing sulfur compounds are used exclusively on currants, because they can cause damage to gooseberry leaves. These include the drug in the form of an emulsion - "Topaz", it is enough to dissolve 2 g in a bucket of water. The preparation "Fundazol" in the calculation of 10 g for the same volume of water or means based on colloidal sulfur with an active ingredient concentration of about 50 g per volume of water of 10 liters.
Mustard powder composition. Proportion - 2 tablespoons of fresh dry mustard powder in 10 liters of water, expired product may reduce the desired effect. The mixture needs to be heated to a boil, experienced gardeners add chopped horsetail and young garlic shoots. The composition must be kept on fire for at least half an hour, then filtered, used to process the entire plant, paying attention to the affected areas and young shoots for prevention.
Compositions with the inclusion of ferrous sulfate. The working solution should contain 300 g of ferrous sulfate per 10 liters of clean water. Processing is carried out after the removal of infected shoots and their parts. Spraying is carried out carefully, it is desirable to process the lower part leaf blades... After removing cut shoots and infected foliage from the soil, it is necessary to carefully process it with the same composition.
Bacterial control method. Based on the preparation of a composition from rotted hay and mullein, the bacteria of the specified composition feed on the powdery mildew fungus. Three treatments per season are enough: immediately before flowering, at the time of flowering, after leaf fall. The treatment is carried out in the evening or in the afternoon in rainy weather when conditions improve. One weight part of rotted hay or cow manure is poured with three times the volume of water. The mixture is infused for three days, after which it is ready for use.

Diseases of currants and gooseberries and their treatment: anthracnose

The main target of anthracosis on garden plot - Red currants. The highest incidence is noted in years with high average daily temperatures and excess moisture.

Pest: fungus-causative agent of plant anthracosis. During the flowering period of shrubs, spores spread. In July-August, the fungus actively spreads, leading to infection.

Signs of the disease

Consider the signs of this gooseberry disease and its treatment. Young shoots, leaves, buds are more susceptible to infection. Brown spots appear in various areas, deformation and twisting occur, leaves fall and shoots dry out. Young berries fall off or become sour.

Control measures

Gooseberries, diseases and their treatment (photo attached) which we are considering, involves the following activities:

Destruction of foliage and infected shoots in spring and autumn.
Digging the soil under fruit plantations with the removal of leaves.

Formulation of formulations for plant and soil treatment

The drug "Hom". Method of preparation: 40 g of the crushed powder is diluted in 10 liters of water, it takes up to two liters of water to process one plant.
Colloidal sulfur complex. Spraying is carried out at the time of flowering and two weeks after it.
Bordeaux mixture. If signs of a disease are detected, at least two consecutive treatments will be required; for this, a standard mixture of 40 g of vitriol and at least 10 liters of water is prepared.

In more serious cases, it will be necessary to process gooseberry and currant bushes four times with a 1% mixture. You need to start application before the period of active flowering, then after it, 2 weeks after the previous treatment, after removing the berries.

To begin with, dissolve 100 g of a copper preparation in 1 liter hot water, bring the volume to 5 liters. In parallel, another mixture is prepared: 100 g of lime is added to 5 liters of water. After dissolving and thoroughly mixing, the solutions are combined by pouring the copper sulfate solution into the lime solution. If the initial solutions are cloudy, strain them. Observe precautions when drugs come into contact with the skin; it is necessary to place the affected area under running water. Substances in the indicated concentrations can be hazardous to the body.

How to reduce the incidence and overcome columnar and goblet rust on fruit plantations?

Consider these gooseberry diseases and their treatment (and care, too, will not be ignored).

Gooseberries, diseases and their treatment (photo attached) need to know, it is also subject to the following ailments:

Columnar rust. Spores ripen on pine shoots in the spring months, from where they settle on gooseberries and currants. The disease is manifested by the appearance of orange spots and pads on the underside of the leaves. Further, the foliage with the spores of the fungus rapidly falls off, the number of berries decreases.

Goblet rust. Dispersal of spores occurs from sedge thickets in late spring. External changes in leaves and berries appear already in the summer, you can not wait for the harvest in the fall, during the illness the leaves and berries fall off.

Control measures

Regular digging of soil in spring and autumn with foliage removal.
Active use of phosphorus-potassium fertilizers.
Destruction of sedge thickets.

Composition for processing plants and soil

Bordeaux liquid of low concentration (1%) is used, treatment begins at the time of bud swelling and flowering, subsequent treatments are carried out after the end of flowering of currant and gooseberry bushes with an interval of a week to 10 days. Final processing should be carried out no later than two weeks before picking berries from the bush. The preparation is applied carefully from all sides. If after the treatment procedure heavy rain has passed, the operation must be repeated.

The composition of the solution is universal 30-40 g of crystalline hydrate of copper sulfate per 10-liter bucket of water. Experienced experts recommend treating not only the aboveground part of the plants, but also after removing the old foliage, spray the soil under the fruit plantations of gooseberries and currants.

Currants and gooseberries. Diseases and their treatment: terry

Pest: Mycoplasma viral infection of terry plants. The carrier of the disease is the currant mite, which primarily affects the kidneys. The disease spreads through the cell sap and affects the entire plant.

Signs of illness

The morphology of black currant leaves is disturbed; instead of five-lobed leaves, more sinewy three-lobed ones are formed. The specific currant smell disappears. The flowers turn purple with an uncharacteristic structure of the corolla and calyx. The fruiting brush is more like a thin twig.

Control measures

Destruction of ticks and aphids on gooseberries and currants.
Top dressing with fertilizers with a high content of manganese, boron, molybdenum, reducing the application of nitrogen fertilizers.

These are the diseases that affect gooseberry. And their treatment is proper care and timely treatment of bushes. In addition, prevention should not be forgotten.

We examined which gooseberries, currants have diseases and treatment.

Gooseberry refers to garden plants that are quite susceptible to diseases and pests. Therefore, the existing gooseberry diseases and their treatment are important knowledge for gardeners.

1 Gooseberry - make a diagnosis

Consider the main diseases and their features:

2 Pests are unwanted guests in your garden

There are no less pests infecting gooseberries than fungal diseases. Let's consider some of them:

A stock of insecticides and a good sprayer should always be at the ready if you want to taste compote or gooseberry jam in the fall.

3 Diseases of the gooseberry and their treatment

All gooseberry diseases and their treatment are approximately the same. The main rule that applies to all types of infections is urgent, affected by the fungus. The branches must be burned immediately.

It is not bad to dilute useful microflora - bacteria that process organic matter - to fight the fungus. They are found in abundance in any organic fertilizer, which should be diluted with water (1 in 10), filtered and sprayed with the resulting liquid. Bacteria, multiplying, will feed on fungi, thereby destroying them. Plus, it's not bad either. However, this is more a preventive way than the ability to quickly cope with diseases.
