Abstract

The invention provides a bactericidal composition containing captan, which comprises effective active ingredient A and effective active ingredient B, wherein the effective active ingredient A is the captan, and the effective active ingredient B is one selected from mancozeb, propineb and metiram; the bactericidal composition comprises the components by weight percent: 2-78% of captan which is the effective active ingredient A, 2-78% of one in the mancozeb, propineb and metiram that is the effective active ingredient B, and the balance of auxiliary agent and excipient. Wettable powder, water dispersible granules and suspending agent can be made from the compounded composition of the captan and the mancozeb or the metiram, and the wettable powder and the water dispersible granules can be made from the compounded composition of the captan and propineb. The bactericidal composition containing the captan has remarkable synergistic action in aspect of preventing and treating citrus tree anthracnose, cucumber downy mildew, wheat powdery mildew and sigatoka.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a fungicidal composition compounded with captan, mancozeb, propineb or mancozeb, which is used for preventing and treating crop downy mildew, powdery mildew, anthracnose and leaf spot sick. 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] Captan, (also known as Capton, Capdan) English name: captan, molecular formula: C 9 h 8 Cl 3 NO 2 S, chemical name: N-trichloromethylthio-4-cyclohexene-1,2-dicarboximide, structural formula...
