Caucasus grape black rot control method

Abstract

The invention discloses a caucasus grape black rot control method. The method comprises the specific steps that American grapes with the high disease resistance are selected; diseased branches, leaves and fruits are thoroughly removed in autumn, concentrated deep burying is performed, and the second-year beginning infection sources are reduced; when grape young shoots begin to grow, excessive branches and tendrils are sheared away in time, light paths are opened, and nutrient content is concentrated; nitrogen, phosphorus and potassium compound fertilizer is applied, a 0.5% monopotassium phosphate and urea mixing solution is applied to leaves, the mass ratio of monopotassium phosphate to urea is 2:1, and the disease resistance is improved; drainage is performed in time in a rainy season, and the phenomenon that the high-humidity pathogenic environment is formed by accumulated water is avoided; when a cluster forming period begins, 50% Fukumi cream wettable powder 2000-fold solution is applied to the integral tree, the spraying frequency is one time per half month, and spraying is performed 4-5 times totally. The combination of agricultural control and pesticide control is adopted, grapes are made to get away from the morbidity environment, the grape yield is greatly improved, the pathogenic sources are eliminated, and orchard economic benefits are increased.

Description

Technical field [0001] The invention relates to a method for preventing and curing grape house blight, which is applied to the technical field of grape disease control. Background technique [0002] Grapes are rich in vitamins, minerals and flavonoids. Flavonoids are powerful antioxidants that can resist aging and scavenge free radicals in the body. At the same time, grapes also contain an anti-cancer trace element that can prevent health. Cells become cancerous and prevent the spread of cancer cells. This shows that grapes have a high nutritional value; in the current market, there are many grape planters, but in the breeding process, growers are often troubled by grape house blight. [0003] Grape house blight mainly damages fruits, fruit stems and cobs. The peak period of disease is from July to September each year. The closer the fruit is to the mature period, the easier it is to get disease. This not only reduces the yield of grapes, but also has a big blow to the confidence ...

AI Technical Summary

Problems solved by technology

July-September is the peak period of the disease. The closer the fruit is to the ripening stage, the more likely it is to get sick, which not only reduces the yield of grapes, but also has a great blow to the confidence of farmers. At present, there is no good drug on the market that can cure the disease. Blight
