Processing grapes after rain in July: how to spray and process

An important aspect of vine care is preventive treatment. In conditions of high humidity, the bushes are affected by diseases. Therefore, it is recommended to carry out processing of grapes in July after rain, especially if there are foci of the disease. Timely measures help prevent the development of fungal diseases on plantations and save the harvest.

Why processing is needed

It would seem that rain is necessary for all living things, but not everything is as good as it seems at first glance. With long, incessant downpours, warm weather and stuffiness, ideal conditions are created for the development of grape disease.Therefore, in order to save the plant and not lose the harvest, it is important to process the bushes in time.

Mushroom spores cause many diseases:

• oidium;
• rot;
• mildew.

The listed diseases can destroy the crop and the entire bush. The most favorable breeding environment is created during the warm rainy days of July.

A lot of spores live in the soil around the plant, falling with raindrops on the foliage of grapes. Even with disease resistance, there is a high probability of infection.

With improper care, heavy rainfall provokes the accumulation of moisture around the trunk, which, in turn, forms mold Its spores are activated and begin to harm the plant. Therefore, it is in July, before the start of the growing season, that the soil around the plant and the bushes themselves are brought into proper condition.To do this, the vine is treated in time against diseases.

Vine preparations

The bushes are especially vulnerable after rain. After the cessation of precipitation, the culture is treated with special preparations. They have not yet come up with chemicals that can cure infected grapes. Therefore, processing is designed to perform basic functions:

1. Kills pathogens to help reduce the risk of disease.
2. When a crop is infected, treated he althy parts of the plant are less likely to spread the disease.

Most gardeners don't know how to treat plantings. Therefore, before the procedure, it is necessary to study information about suitable means. A complex preparation is suitable for processing, which is intended for spraying after precipitation. Special tools affect different types of fungi, pests and mold.

Drugs work best:

1. "Topaz". The complex preparation protects against various fungal diseases, prevents mildew from spreading. Helps reduce the risk of anthracnose. Used for prevention and at the initial stage of diseases.
2. Strobe. Spraying with the product after rain in hot weather helps fight against the development of downy mildew and prevents infection of the vine with oidium. The main advantage is safety for pollinating insects, approved for use during flowering.
3. "Thiovit". Destroys various types of mold and helps in the fight against spider mites.
4. Ridomil Gold. The most effective remedy. It has low toxicity. Reliably protects the culture from the fungus, enveloping the leaves from the outside, and acts from the inside.
5. Bordeaux blend.An effective and time-tested tool. Helps with the main diseases of the vineyard, but has a high toxicity. When working with the drug, you will need to observe increased safety measures and cook strictly according to the recipe. Overdose leads to negative consequences. It is allowed to process at a temperature of 25-36 degrees. Frequent use during ripening concentrates high copper content in fruits.

Any of the listed drugs, if the recommendations are followed, will benefit the plantations.

Folk remedies

If there are no obvious symptoms of diseases, or with minor damage, you can perform treatment with folk remedies. They have a harmless effect on plantings, but are less effective. They are recommended to be used as a prophylactic for the processing of grapes or at the first signs of the onset of diseases.It is worth analyzing the main spraying methods against the reproduction of bacteria in rainy weather.

Soda solution

Suitable for use at all stages of the growing season. In July, warm weather helps to create a film on the culture, which has an alkaline reaction. The solution does not allow germinating fungi. Bushes are treated before and after flowering.

To prepare the solution use:

• water - 5 l;
• soap - 25 g laundry;
• baking soda - 25g

Products are dissolved and sprayed every week.

Copper vitriol

The blue drug in granules is harmless to the culture. But when dissolved, it becomes highly acidic and can harm plantings.

Colloidal sulfur

Treatment is carried out at the very beginning of the development of ailments. In order not to cause irreparable harm to plantings, you will need to carefully adhere to the necessary proportions indicated by the manufacturer. Prepare a solution in warm water. The powder is completely dissolved. Use only freshly prepared product. Spraying with a solution protects the culture for two weeks. Treat bushes after rain.

Pest prevention and control

Most common pests:

• grape itch;
• various types of mites.

These pests are also called felt mites. They are represented by small insects, the length of which does not exceed 0.2 mm. They suck the juice from grape leaves, piercing them from below. The insect itself is difficult to see. A yellow swelling appears at the puncture site, which is visible from the top of the leaf.Felt web is formed from below. As a result, the foliage begins to slowly dry out.

Fight:

• branches are tied high above the soil;
• remove diseased leaves.

For the prevention and control of pests, plantings are sprayed with drugs:

• "Kleschevit";
• Fitoverm.

It is important to properly prepare for the procedure and carry it out correctly.

Preparation for work

There are a variety of pest control methods, but chemical and biological methods remain effective.

Preparation rules:

• remove damaged leaves;
• cut;
• tie up the vine;
• burn sick, damaged parts;
• break up clods of earth, loosen the soil and level the ground.

Use only the amount specified by the manufacturer for processing.

Processing steps

When scheduled processing follow the recommendations:

• The plants are treated after rain in the evening, after sunset.
• To achieve the result, the composition must remain on the leaves for a long time. Before processing pay attention to the weather forecast. If rain is likely to continue, spraying is postponed.
• When processing during the scorching sun, burns appear on the sheets.
• In the heat, the solution evaporates intensively, thereby reducing the effect of the drug.
• Carefully process the shoots that have contact with the soil. The chemical only works on treated parts.

Prevention is an important condition for caring for the vineyard after the rains. Even resistant varieties are given favorable conditions that help prevent the spread of pests and diseases.
