Problems solved by technology

The traditional control method, long-term use of single pesticide control, leads to enhanced resistance of pathogens, the effect of drug control is getting worse year by year, the utilization rate of pesticides is reduced, and the yield and quality of grapes are reduced.

example 1

[0013] 1. Dormant period management: During the dormant period in autumn and winter, remove diseased fruit ears, diseased branches and tendrils, scrape off old bark with pathogenic bacteria, remove dead branches, fallen leaves, and diseased fruit ears in the orchard, and burn the cleaned sick residues in a centralized manner. 1 time of deep plowing and tumbling;

[0014] 2. Management during the growth period: after the field infection occurs during the growing season, cut off the diseased ears and branches and vines found in the early stage, clean up the diseased grains that have landed, take them out of the garden and bury them deeply; apply more organic fertilizers; increase the fruiting parts. Combining vine tying and flower thinning and fruit thinning, make the fruiting part as high as possible to more than 30 cm;

[0015] 3. Chemical control:

[0016] 1) Before spring: Mix 500 grams of thiram, 500 grams of sulfur powder, and 12 kilograms of calcium carbonate evenly, and...

Abstract

The invention discloses a prevention and cure method for white rot of grapes. According to the prevention and cure method, during the dormancy period of the grapes in autumn and winter, all media capable of carrying pathogens are eliminated in a grapery; and during the growing period, the grapes are prevented from being infected through applying more organic manure, thinning blossom and fruit, and improving fruit position. During the period from the pre-blossom to ripened fruit, seven pesticides of thiram, folpet, benomy, chlorothalonil, thiophanate-methy, carbendazim, and Mancozeb M-45 are used; through scientific and reasonable mixing ratio and collocation of the different pesticides, the resistance of the pathogens to a single pesticide is reduced; the synergism of the pesticides is improved; the consumption cost of the pesticides is reduced; and the prevention and cure efficiency of the white rot of the grapes is greatly improved.

Description

technical field [0001] The invention relates to fruit tree cultivation, belongs to the technical field of disease prevention and control, in particular to a method for prevention and treatment of grape white rot. Background technique [0002] Grape white rot is commonly known as "water rot" or "ear rot". The disease mainly affects fruit ears and branch tips, and leaves can also be affected. Usually, the disease occurs first on the branch tips. Dark brown at the edge of brown, and then develop into long strips of dark brown, with small off-white dots densely growing on the surface. The onset and severity of white rot are closely related to rainfall, cultivation methods, and tissue maturity. The rainy season is early, the onset is early, the rainfall is heavy, the onset is heavy, the rainy season is long, and the onset lasts for a long time. There is a peak of incidence after rain, especially in storms or hail, which often cause a pandemic, and the closer the ear is to the gr...
