Abstract

The invention discloses a pesticide composition containing pymetrozine and picoxystrobin, a preparation and application thereof. The active ingredient of the pesticide composition is a binary compound of pymetrozine and picoxystrobin, wherein the weight ratio of the active ingredients pymetrozine and picoxystrobin is 1:80-80:1. The present invention is prepared into one of aqueous emulsion, suspending agent, wettable powder, water dispersible granule and seed treatment agent with known methods, and the pesticide composition of the present invention is mainly used for preventing and treating vegetables, cotton, fruit trees, various Pests and diseases of field crops and seeds.

Description

[0001] The invention belongs to the technical field of pesticides and has a synergistic effect of a pesticide composition containing pymetrozine and picoxystrobin, a preparation and an application thereof. The active ingredients are pymetrozine and picoxystrobin. Background technique [0002] Picoxystrobin, common name in English (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 ...
