Abstract

The invention discloses a bactericidal composition, the active ingredients of which are flufenapest and pyraclostrobin, and the mass ratio of the two is 1:50-50:1. The composition has obvious synergistic effect and good safety, and is suitable for preventing and controlling powdery mildew and rust of vegetables, fruit trees and cereal crops.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing fludiofen and its application in 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 the powdery mildew family of fungi; rust is a worldwide disease caused by the parasitism of rust fungi in the fungus. [0003] In production, chemical pesticides are mainly used to control powdery mildew and rust. At present, it mainly relies 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] Flufenoxystrobin, English common name: flufenoxystrobin, test code: SYP-3759, is a methoxyacryl...
