Fungicides for grapes: varieties, instructions for use, processing rules

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

Features of fungicides for grapes

Grapes are susceptible to 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 show high resistance to diseases, but sometimes even this does not save from the problem:

Fungicides are designed to destroy diseases and prevent further spread of the infection.
Preparations are used to protect young and adult plants.
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 that are divided into three types.

System

Systemic preparations 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 carried along with the juice to all organs of the plant. As a result, the growth and spread of pathogenic microorganisms is suppressed.

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

quickly penetrate into the pathological focus;
Won't wash off with water;
components are able to get rid of viral and fungal infections;
three treatments are enough for the whole season to provide reliable protection against diseases.

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

Contacts

Features of the use of contact preparations against grape diseases:

The finished solution should be evenly distributed over the entire aerial part of the plant. Be sure to process the trunk, leaves and vine.
The procedure is carried out in dry, calm weather. If it rained, then spraying is repeated again.
The disadvantage of using such fungicides is repeated processing. To achieve reliable protection, at least 7 treatments are required.
Contact fungicides are more suitable for prevention. They do not destroy the mycelium, so he althy plants or bushes with damaged parts 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

Fungicides of complex action are modern. Differ in efficiency and high speed of impact on the lesion:

Means combine the properties of contact and systemic drugs.
Be especially careful when using products, as the components are toxic to others.
Substances fight infection at any stage of the disease.

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

kind of infection;

Grape processing scheme

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

Therefore, it is important to follow the spray pattern:

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

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