Abstract

The invention provides captan sterilization composition which comprises an effective active ingredient A and an effective active ingredient B, wherein the effective active ingredient A is captan, the effective active ingredient B is one of thiophonate-methyl, prochloraz and Prochloraz manganese, and the sterilization composition comprises the following ingredients (by weight): 2-78 percent of effective active ingredient A, i.e., captan, 2-78 percent of effective active ingredient B, i.e., thiophonate-methyl, prochloraz and Prochloraz manganese, and accessory ingredient and excipient for the rest. The composition of the captan and the thiophonate-methy can be made into wettable powder, water dispersible granules and suspending agent, and can be used for preventing and treating anthracnose of cucumber, alternania mail Roberts and venturia pirina with remarkable synergism; the composition of the captan, the prochloraz and the salt thereof can be made into wettable powder, water dispersible granules, suspending agent and suspension emulsion and can be used for preventing and treating anthracnose of citrus trees with remarkable synergism.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a bactericidal composition compounded with captan, thiophanate-methyl, prochloraz or prochloraz manganese salt, which is used for preventing and treating pear tree scab and apple leaf spot defoliation , Cucumber powdery mildew, Citrus anthracnose. technical background [0002] Fungi are the most important plant pathogenic bacteria, and more than 70% of plant diseases are caused by fungi. Because of the complex pathogenic factors, it is very difficult to control them. In recent years, with the adjustment of rural planting structure, the planting area of ​​fruit trees and vegetables has been increasing, and the occurrence of many fungal diseases on fruit trees and vegetables has also increased, causing huge economic losses. [0003] Apple tree spot defoliation: Apple is the fruit tree variety with the largest planting area in my country. However, due to the serious occurrence o...
