The main diseases and pests of gooseberries: types, as they appear, control measures
Every gooseberry grower can run into diseases and pests in his plant. In the article you will read about the main pests and diseases of gooseberries, methods to overcome them, as well as what precautions must be observed when working with chemical agents.
The main gooseberry diseases, their treatment and prevention
To properly treat gooseberries for diseases, you need to know the signs of the disease and the measures necessary to improve the plant. It is also worth observing prophylaxis to minimize the possibility of illness.
Did you know? Currently, there are about 1,500 varieties of gooseberries in the world.
Among the most common plant diseases, the following can be distinguished.
|Disease||Causes||Treatment + Prevention|
|Powdery mildew||The bush can become infected with this disease due to the transfer of fungal spores by wind or insects. Mushrooms with spores provoke the appearance of white plaque on the plant, similar to mold.|
The affected sheets curl, stop growing and dry out. The ovaries fall, which reduces productivity, as a result, the bush may die.
|To overcome the disease, you should spray the bush with a solution of copper sulfate. To prepare it, you need to dissolve 80 g of the substance in 10 l of water. You can also use drugs "HOM" or "Topaz".|
To prevent the disease of the plant with powdery mildew, you need to dig the soil near the trunk circles, as well as spray the bush in early spring with hot water, the temperature of which is +45 ... + 50 ° C.
|Sphereotka - powdery mildew||The reasons for the emergence of the sphere library are the transmission of spores by air. As a result of the disease, whitish spots appear on the plant after the flowering period. Over time, spots acquire a brownish tint. The disease provokes a slowdown in the processes of gooseberry development, as a result of which the leaves curl, and the formed ovaries fall off.||To cure the spherical library, it is recommended to use the Fitosporin preparation. You can also carry out treatment in a folk way: fill a 3-liter container with wood ash and coal, add water and put on fire. After boiling, cook the mixture for 30 minutes, then add 30–40 g of laundry soap. After this, cool the mixture, stir and apply for spraying.|
Preventive measures to prevent sferoteka are spring digging of the soil and spraying with drugs that strengthen the immunity of the plant.
|Rust||It occurs locally and is carried by gusts of wind or insects. The fungus carries the winter on fallen leaves of currant and on conifers. The first signs of the disease are spots or streaks of rusty-brown color on the lower part of the sheets, on the upper part of the spot are light yellow. Rust causes evaporation of moisture in the plant, drying and falling of leaves.||To treat rust, it is necessary to spray the culture with a solution of copper sulfate (40 g of vitriol per 10 l of water).|
Prevention of the disease is the burning of fallen leaves and digging the soil around the bush. You should also avoid planting this crop next to conifers.
|Anthracnose||The disease is provoked by fungi that first affect the leaves of the plant. Dark brown spots appear on them, increasing in size over time. After the leaves dry and fall, the growth of young shoots and productivity decreases, the sweetness of the berries decreases.||Having discovered the first signs of anthracnose, it is necessary to spray gooseberries with a solution of copper sulfate (for 10 liters of water you need 40 g of vitriol).If the disease has severely affected the culture, it should be treated at least 4 times with 1% Bordeaux fluid.|
To prevent the development of the disease, you need to collect and burn all fallen leaves. In early spring, you should check whether there are uncleaned leaves under the bush that should be immediately destroyed.
|Septoria||The cause of septoria is a fungus that is carried by the wind or insects. This disease causes small gray spots with a brown border to appear on the plant, after which black dots appear on the plaque. Leaves curl and dry. If untreated, the bush dries completely.||Septoria treatment should be carried out with fungicides, for example, Bordeaux fluid at the rate of 100 g of fluid per 10 liters of water.|
Prevention of the onset of the disease is the treatment of gooseberries with a solution of potassium permanganate.
|Mosaic||The mosaic carriers are sucking insects, diseased plants and an unsterilized tool after working with affected bushes. The first sign of mosaic damage is the appearance of a yellow pattern on the leaves. Leaves become small and wrinkled, the bush stops growing, and productivity decreases.||This disease is practically not cured, diseased bushes need to be dug up and burned immediately.|
Preventive measures to protect the plant from illness are the purchase of healthy seedlings and the treatment of shrubs with aphids and ticks.
|Gray rot||Occurs with improper or untimely care. The first signs of the disease are gray spots in the lower part of the shoots, decay and decay of the fruit.||In order to combat gray rot, Zircon, Chorus, and Strobi preparations are actively used.|
Preventive measures to prevent gray rot are regular thinning of the bushes in order to avoid high humidity, and also to remove the affected parts of the plant in order to prevent the spread of the disease.
|Verticillus wilting||The causative agents of the disease are fungi that penetrate the vascular system of the culture through the roots and secrete toxins from which the plant dies. The first sign of the disease is vasodilation. In affected plants, growth slows down, leaves fade, turn pale and fall off. If untreated, the bush dies after 2-3 years.||With manifestations of the disease, you need to spray and water the plant under the root with a 0.2% solution of Fundazole.|
Prevention of this disease is attentiveness to the choice of planting site and planting material that are not affected by the disease. It is also desirable to introduce mineral dressings with a predominance of potash.
|Alternariosis||Carried by wind, raindrops and insects. It is characterized by the appearance of grayish-black large spots along the edge of the sheets. After the affected parts of the plant are covered with olive bloom, the bush weakens, the leaves fall off.||To combat the disease, fungicides such as Bravo, Polyram or Ordan are used. For preventive purposes, it is necessary to promptly collect plant debris and conduct annual spraying with 1% Bordeaux liquid.|
|Ascochitosis||The disease affects healthy plants through the remnants of the previous crop. The disease is characterized by the appearance of convex spots of brown color with a dark border on the stems, leaves and fruits. Affected tissues quickly dry out, which leads to the death of the plant.||The affected parts of gooseberries must be dusted with a mixture of copper sulfate and chalk and sprayed with fungicides during the growing season.|
To prevent the disease, it is necessary to plant only healthy seedlings, destroy the remnants of fallen leaves and prevent thickening of the culture.
In order not to harm either yourself or the plant when treating gooseberries with chemicals, it is important to observe the following precautions:
- Use only certified products approved for sale.
- Do not store chemicals near food.
- Before processing plants, wear protective clothing and cover the mouth and nose with a cotton-gauze bandage.
- Do not consume liquid or food during processing.
- After processing, thoroughly rinse and dry the auxiliary materials.
Important! Gooseberry treatment with any drugs should be carried out no later than 2 weeks before harvesting.
The main mistakes in the fight against gooseberry diseases
Experts identify several typical mistakes made by inexperienced gardeners in the fight against plant diseases:
- spraying without removing the affected parts of the plant;
- use of the same chemical preparation;
- carrying out plentiful and frequent watering of a bush;
- leaving cut off affected parts of gooseberries in the area.
Gooseberry pests and control measures
Gooseberry pests can cause a lot of trouble to the gardener.
Important! Process gooseberries to rid them of pests and diseases, preferably in the evening or on a cloudy day.
Consider a description of the main pests of this culture, as well as measures aimed at getting rid of these uninvited guests.
|Pest||Signs of defeat||Fight + Prevention|
|Fire||This pest is a brown butterfly; an oval white stripe runs along its costal edge. The larva is a gray-green caterpillar with black spots on its sides.|
The main harm of gooseberries does not come from a butterfly, but from a caterpillar weaving a web on leaves, peduncles and fruits. The larva of this pest gnaws the entire inside of the fruit, which redden, rot and fall.
|To combat pests that have already affected the bush, it is recommended to treat the bushes with Kinmix or Karate preparations.|
Prevention of the appearance of this pest is the periodic digging of land under the bush throughout the season and its hilling in autumn by 10-12 cm. You can also plant tomatoes or mint next to gooseberries.
|Glassmaker||The butterfly of this pest is similar to a wasp with a black body and three yellow stripes on its abdomen. In addition to gooseberries, she also prefers red and black currants. The glass-box does not practically appear on the surface, spending almost all its life in the stem. You can find out about the presence of gooseberries in the glasshouse during pruning. Glass-afflicted plants give small foliage, slow growth and fade.||The drugs that will help get rid of the glass-case are “Lipidocide”, “Fitoverm” or “Akarin”.|
Preventive measures to prevent this pest are the processing of cuts on the tops of shoots with garden varieties and spraying after flowering with infusion of wormwood or onion husks.
|Aphid||These are small pests with an ellipsoid body and a different color: from light green to black. These insects drink the cell sap of the plant, causing the gooseberry to lose chlorophyll. External signs of aphid damage include twisted shoots, yellowing of young leaves, and spoilage of fruits.||The main protection against aphid gooseberries are insecticides. Among them are popular "Fufanon", "Aktara" and "Actellik".|
Prevention of aphid prevention on the site is the regular application of complex fertilizers, annual pruning, as well as the proximity to dill or tansy.
|Shield||These insects have a hard shell of brown color. The scabbard is attached to the leaf of the plant, as a result of which a yellow spot appears on it. Over time, the entire leaf turns yellow, curls and falls. Gooseberries gradually wither and may die.||Young individuals are easily destroyed by drugs like Altara or Actellik.Adult individuals are resistant to chemicals, they must be destroyed by cleaning off the gooseberries with a metal brush.|
Preventive measures to prevent the appearance of scale insects are regular washing of the bush with a soft cloth with a soap-kerosene solution.
