Abstract

The invention discloses a bactericidal composition containing procymidone. The bactericidal composition comprises an active component A and an active component B, wherein the active component A is selected from the procymidone, the active component B is selected from anyone of kresoxim methyl, pyraclostrobin and trifloxystrobin, and a weight ratio of the active component A and the active component B is 1 : 80 to 80 : 1. Auxiliary agents are added into the active components to prepare wettable powders, water dispersible granules, suspension, suspension emulsion, water emulsion and micro-emulsion which can be used for preventing powdery mildew, blight, downy mildew, botrytis, eqpidemic disease, anthracnose, , sheath blight, alternaria leaf spot, Cladosporium cucumerinum, brown rot, leaf blight and rust diseases. The composition is wide in bactericidal spectrum, small in dosage, resistant to rain erosion and obvious in synergy.

Description

Technical field [0001] The invention belongs to the technical field of pesticides and relates to the application of a procymidol-containing bactericidal composition on crop diseases. technical background [0002] Procymidone, molecular formula: C 13 H 11 Cl 2 NO 2 , Chemical name: N-(3,5-dichlorophenyl)-1,3-dimethylcyclopropane-1,2-dicarbonylimine. Procymidazole is a systemic fungicide that is particularly effective against fungi of the genus Botrytis and Sclerotinia. It can prevent and control gray mold and sclerotinia in fruit trees and vegetable crops. It is also effective against fungi that are resistant to benzimidazole. . After use, the protective effect is good and lasts for a long time, and it can prevent the development and spread of lesions. Use it before or in the early stages of crop disease to achieve satisfactory results. Pythium has outstanding protective effect on crops, has a long lasting effect, and can effectively prevent the development of disease ...
