When cultivating grapes, the main task facing gardeners is to provide conditions for the growth and development of shrubs to further obtain an excellent harvest of delicious and healthy berries. Treatment of grapes from diseases after winter includes a number of measures against infections and fungus.
Terms of spring processing of grapes from diseases
First processing
The first processing of grapes in the spring is carried out with copper sulfate after removing the covering material, which the plant was made in winter. When preparing a solution to combat fungal diseases 200 g of copper sulfate is diluted in 10 liters of water. For young vitriol plants, you should take 2 times less. Experienced gardeners prepare a mixture of a solution of copper sulfate and lime milk. To this end, 100 g of copper vitriol is bred in one container. To crystals of the substance are better dissolved, they must be filled with hot water. While the Bordeaux liquid (the so-called vitreous solution) cools, in the other tank limy milk is prepared from 100 g of quicklime (or 150 g of slaked lime) and 10 liters of water. A solution of copper sulfate is poured into the lime milk with constant stirring. That the composition does not evaporate during the spraying process and kept on the treated plants, it is recommended to add laundry soap or glycerine.
Second processing
Before the flowering, the second processing of the culture is carried out. In more southerly regions this period falls on the 20th of April, in the temperate climatic zone - at the beginning of May. At the same time for the processing of grapes are used such drugs: Ridomil, Golden Sparkle, Topaz, Theovid-Jed.
A remarkable effect gives the processing of grapes Gibberellin - a natural regulator of plant development. The main substance in the preparation is gibberella - fungus, which activates the vegetative process. We recommend that you use the following advice when preparing the solution: first dissolve it in a small amount of alcohol, and then dilute it with water. Fruit brushes are dipped in a container with a solution, bypassing all plants. Thanks to Gibberellin, more fruit is fastened, the growth of bunches is stimulated and the size of berries is increased. Similarly, affect Gibbersib, Cveten, Bud, Ovary, Gibberross and other drugs from this series. It is important before buying a product to see if the composition contains gibberellic acid or its salts.
Subsequent processing
During the formation of grape bunches, treatment is conducted against insect pests. Bushes are sprayed with Oxychom, Quadrice, Mospilan. You can again treat the grapes with Gibberellin, especially if the berries of the plant, cultivated on the site, are prone to grinding.
Biopreparations for grapes processing
Those who do not like the use of chemicals, have the opportunity to use non-toxic biological products.
Trichodermine The fungus-saprophyte, found in the preparation, decomposes organic substances in the soil into compounds of nitrogen, phosphorus and potassium, thus enriching the earth. In addition, trichoderma suppresses many pathogens of grape diseases, including black leg, scab, late blight, powdery mildew . It is very important that a non-toxic preparation can be mixed with other fertilizers.
Phytosporin
At the heart of the drug is a hay bacillus that suppresses parasitic fungi and prevents the development of bacterial diseases. Fitosporin is absolutely non-toxic, the fruits can be eaten the next day, after washing them. You can use another preparation based on a hay bacillus - Phytodor. Only given that it contains bacteria in the form of dry spores, the solution should be prepared 1 to 2 hours before the start of spraying.
The best way to prove yourself and some other biologics: Planzir, Pentafag-S, Boverin, Guapsen.
It should be recalled that the processing of grapes, as, indeed, other garden plants, it is better to spend in the evening.
