Abstract

The invention discloses a pesticide composition containing picoxystrobin and pyrethroids, a preparation and an application thereof. The pesticide composition contains an active ingredient A, an active ingredient B and an auxiliary agent. Weight ratio of the active ingredient A to the active ingredient B is 1: 80-90: 1. The active ingredient A is picoxystrobin. The active ingredient B is one selected from alphamethrin, cypermethrin, bifenthrin, lambda-cyhalothrin and deltamethrin. The composition can control various plant diseases and insect pests, has an obvious synergistic effect, and has high activity to oomycete, ascomycete and deuteromycetae germs on fruit trees, flowers, cotton, tea trees and vegetables and imported cabbageworm, plutella xylostella, cabbage caterpillar, cotton bollworm, peach fruit moth, leaf miner, european corn borer, red spider, tetranychid and the like. in addition, dosage of the pesticide is minimized, residual quantity of the pesticide on crops is reduced, and environmental pollution is alleviated. The pesticide composition is safe to human and livestock, has good environmental compatibility, and is not easy to generate drug resistance for plant diseases and insect pests.

Description

technical field [0001] The invention belongs to the technical field of pesticides and has a synergistic pesticide composition, and relates to a pesticide composition containing picoxystrobin and pyrethroids, a preparation and an application thereof. Background technique [0002] Picoxystrobin, English common name: Picoxystrobin, molecular formula: C 18 h 16 f 3 NO 4 , Chemical name: (E)-3-methoxy-2-[2-[6-(trifluoromethyl)-2-pyridyloxymethyl]phenyl]methyl acrylate. Picoxystrobin is a mitochondrial respiration inhibitor, and its mechanism of action is to inhibit mitochondrial respiration through electron transfer between cytochrome b and C1. Effective against strains resistant to 14-demethylase inhibitors, benzamides, dicarboxamides and benzimidazoles. Once taken up by the leaves, picoxystrobin moves in the xylem, following the water flow in the transport system; it also flows in the gas phase on the leaf surface and flows in the xylem after being absorbed into the leaves...
