Sterilization composition containing penflufen and methoxy acrylate

Abstract

The invention discloses a sterilization composition containing penflufen and methoxy acrylate. Effective components of the sterilization composition comprise an active component A and an active component B, the active component A is penflufen, the active component B is selected from anyone of azoxystrobin, kresoxim-methyl, dimoxystrobin, orysastrobin, metominostrobin and pyraoxystrobin, and a weight ratio of the active component A to the active component B is 1:80-80:1. The composition has the advantages of synergistic effect on many diseases harmful to the agricultural production, reduction of the pesticide consumption, reduction of the residual quantity of pesticides on crops, mitigation of the environment pollution, safety to humans and animals, good environmental compatibility, and difficult pesticide resistance of the diseases.

Description

technical field

[0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing flufenadine and methoxyacrylate to crop diseases. Background technique

[0002] Penflufen (penflufen): Molecular formula is C 18 h 24 FN 3 O, the chemical name is 2'-[(RS)-1,3-dimethylbutyl]-5-fluoro-1,3-dimethylpyrazole-4-carboxanilide, and flufenapyridine is a A succinate dehydrogenase inhibitor, mainly acts on the electron transport complex II of the respiratory chain, blocking energy metabolism. It can control seed-borne and soil-borne basidiomycete and ascomycete diseases, mainly potato black mole caused by Rhizoctonia, wheat sheath blight, rice sheath blight, rape sclerotinia, etc., as well as wheat smut , Wheat smut, corn small spot and so on. The treated seeds can absorb flufenapyridine during the germination process, and transmit it to other parts of the plant through the xylem to protect the crops.
