Abstract

The invention discloses a pesticide composition containing picoxystrobin and metaflumizone and its preparation and use. The pesticide composition contains active components of picoxystrobin and metaflumizone and a weight ratio of picoxystrobin to metaflumizone is in a range of 1: 80 to 80: 1. The pesticide composition can be processed to form a suspending agent, particles, wettable powder, water dispersible granules or a seed treatment agent. The pesticide composition containing picoxystrobin and metaflumizone has a reasonable formula, good bactericidal and insecticidal effects, and obvious synergism, can delay resistance to pesticides, is safe for crops and has a low drug use cost. The pesticide composition containing picoxystrobin and metaflumizone can be used for a plurality of crops such as cotton, corn, vegetables, potato, soybean, banana and other fruit trees, and their seeds.

Description

technical field [0001] The invention belongs to the technical field of pesticides and has a synergistic pesticide composition. Specifically, it is a pesticide composition containing picoxystrobin and metaflumizone, a preparation and its application. The active ingredients are picoxystrobin and metaflumizone. Metaflumizone. 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 ...
