Instructions for the use of fungicides for grapes and the best preparations

Among the wide list of fungicides for treating grapes, you need to choose the most effective and safe drug. All of them prevent the spread of crop-hazardous diseases. The solution is made in accordance with the recommendations specified in the instructions. You cannot independently exceed the dosage of the components. Preventive and therapeutic spraying is carried out at certain periods in compliance with certain rules.

Features of fungicides for grapes

Grapes are susceptible to infection by various infections. Diseases negatively affect not only the quantity and quality of the crop, but can also lead to the death of the bush. Many varieties have been bred that exhibit high resistance to diseases, but sometimes even this does not protect from the problem:

1. Fungicides are designed to destroy diseases and prevent further spread of infection.
2. The preparations are used to protect young and adult plants.
3. When used correctly, organic fungicides are harmless to humans and animals. Chemical components do not accumulate in fruits and do not change their taste.

Varieties

Manufacturers offer a large list of chemicals, which are divided into three types.

System

Systemic drugs are used for preventive purposes, as well as for the treatment of already infected plants. The components of the solutions are able to penetrate deep into the tissues and are distributed along with the juice to all organs of the plant. As a result, the growth and spread of pathogenic microorganisms is suppressed.

Systemic drugs, unlike contact ones, are characterized by the following properties:

• quickly penetrate into the pathological focus;
• are not washed off with water;
• components are able to get rid of viral and fungal infections;
• Three applications over the entire season are enough to provide reliable protection against diseases.

The disadvantage is that the fungus quickly adapts to the incoming components, so fungicides of the same group are not used more than twice a year.

Contact

Features of the use of contact drugs against grape diseases:

• The prepared solution should be distributed evenly over the entire above-ground part of the plant.Be sure to treat the trunk, leaves and vine.
• The procedure is carried out in dry, windless weather. If it rains, spraying is repeated again.
• The disadvantage of using such fungicides is the repeated treatment. To achieve reliable protection, at least 7 treatments are required.
• Contact fungicides are more suitable for prevention. They do not destroy the mycelium, so healthy plants or bushes from which damaged parts have been removed should be treated.
• It is worth following the established scheme. If the next treatment is not carried out on time, then the damaged plant should be sprayed with systemic or complex preparations.

Complex

Modern fungicides have complex effects. They are distinguished by their effectiveness and high speed of impact on the lesion:

• The products combine the properties of contact and systemic drugs.
• Particular care should be taken when using the products, as the components are toxic to others.
• The substances fight infection at any stage of the disease.

The most effective drugs

Among the many preparations, gardeners highlight the following.

"Antrakol"

The drug is intended for the control and prevention of common fungal diseases:

• Belongs to the group of contact drugs.

Colloidal sulfur

For preventive and therapeutic purposes, a solution based on colloidal sulfur is used:

• To prepare a medicinal solution, you need to add 100 g of the substance to a bucket of water. For preventive spraying, it is enough to take 85 g of the substance.

inkstone

It is advisable to treat grapes with a solution based on iron sulfate 1% in early spring, before buds open. The solution reduces the risk of infection.

The component protects the plant from late frosts, as it delays bud break. In the fall, the grapes are treated with a 3% solution of iron sulfate.

Which one is better to choose?

To choose the right drug, you must take into account some conditions:

• type of infection;
• stage of the disease;
• growing season of grapes.

Grape processing scheme

It is easier to prevent the appearance of fungal diseases than to fight an infection that has already appeared.

Therefore, it is important to follow the spraying schedule:

• Processing begins in early spring, in mid-March.
• Before, during flowering and after flowering, spraying is repeated again.
• Summer treatment is carried out if the weather is rainy and cloudy.

Dilution and use of solutions is carried out according to the instructions for use.
