Abstract

The invention discloses a bactericidal composition containing SYP-Z048. The effective components of the bactericidal composition are SYP-Z048 and fluopicolpkd, and the weight ratio of SYP-Z048 to fluopicolpkd is 1:50-50:1. The bactericidal composition has the advantages of prominent synergetic effect and high safety, and can be used to treat and prevent powdery mildew of vegetable, fruit trees, and cereal crops.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing pyridoxazole 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. [0003] In production, chemical pesticides are mainly used to prevent and control powdery mildew, and currently mainly rely on benzimidazoles, 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. [0004] Pyridoxazole (SYP-Z048), chemical name: N-methyl-3-(4-chloro)phenyl-5-methyl-5-pyridine-3-methyl-oxazoline, molecular formula: C 16 h 17 ClN 2 O, a new type of pesticide in...
