Abstract

The present invention discloses a bactericidal composition containing isopyrazam and an application thereof. Effective ingredients of the composition are isopyrazam (A) and imidazole bactericide (B), wherein B is selected from one of carbendazim, thiophanate methyl, benomyl and thiabendazole; and a mass ratio of A to B is 1:50-50:1. The composition has obvious synergistic effect and good safety, is suitable for controlling agricultural crop powdery mildew, particularly suitable for controlling vegetable, fruit tree and cereal crop powdery mildew.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing pyraclostrobin and its application for preventing and treating crop diseases, and belongs to the technical field of pesticides. Background technique [0002] Powdery mildew is a widespread worldwide disease caused by fungi in the family Erysiphyceae. In production, chemical pesticides are mainly used to prevent and control powdery mildew, and currently mainly rely on benzimidazoles, hydroxypyrimidines, phenoxyquinolines, triazoles and methoxyacrylate fungicides. These agents have produced varying degrees of resistance due to long-term use, and the control effect has decreased. In addition, triazole agents can inhibit the growth of crops when used in large doses, and easily cause phytotoxicity. Therefore, it is urgent to research and develop new effective control agents.
