Abstract

The invention relates to a bactericidal composition comprising the effective components of cyprodinil (A) and other bactericide (B), wherein the B is any one of diethofencarb, pyrimethanil, procymidone, dichlozoline and dimethachlon, and the mass proportion of the A to the B is 50:1-1:50. After the A and the B are compounded, the bactericidal composition has an obvious synergistic action and is used for the prevention and treatment of diseases on crops, such as fruit trees, cotton, paddy, vegetables and the like, especially fungoid diseases.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a compound bactericidal composition containing cyprodinil. Background technique [0002] In recent years, due to single and unscientific use of drugs, many diseases have become resistant to the currently used pesticides, such as cucumber gray mold, grape gray mold, tomato gray mold, etc., which has become a major problem in chemical control. At the same time, frequent application of pesticides has caused increased burden on farmers and increased environmental pollution. Therefore, there is an urgent need for new varieties of fungicides with high efficiency, low toxicity and environmental protection. [0003] Cyprodinil, the English common name of Cyprodinil, and its chemical name 4-cyclopropyl-6-methyl-N-phenylpyrimidin-2-amine, is a protective fungicide whose mechanism of action is a methionine biosynthesis inhibitor. After spore germination, it acts to inhibit the penetration pro...
