Clodinafop-propargyl and butachlor containing weeding composition and application thereof

Abstract

The invention discloses a clodinafop-propargyl and butachlor containing weeding composition and an application thereof. According to the weeding composition, clodinafop-propargyl and butachlor serve as major active components and the mass ratio of clodinafop-propargyl to butachlor is (1 to 99): (1 to 99), and the total mass percentage of clodinafop-propargyl and butachlor in the weeding composition is 10-80%. The weeding composition disclosed by the invention can be applied to the post-emergence weeding of wheat fields and particularly has a remarkable effect when the weeding composition is used for controlling Gramineae weeds and broad-leaved weeds in the wheat fields. Compared with single agents, the weeding composition disclosed by the invention has the advantages that the resistance to the weeds is retarded on the premise of improving drug effect, the weeding spectrum is broad, the effect duration is long, and the weeding composition has safety to both wheats and succession crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and specifically relates to a binary compound herbicidal composition of clodinafop-propargyl and butachlor, which can be applied to post-emergence weeding in wheat fields. Background technique [0002] Clodinafop propargyl, also known as top, chemical name: R-2-[4-(5-chloro-3-fluoro-2-oxypyridine)-phenoxy]-propiolic acid, belongs to phenoxycarboxylic acid herbicide Agent, structural formula: [0003] [0004] Clodinafop-propargyl is an acetyl-CoA carboxylase (ACCase) inhibitor, a systemic conductive herbicide, absorbed by the leaves and leaf sheaths of the plant, conducted by the phloem, and accumulated in the germinal tissues of the plant, inhibiting the carboxylation of acetyl-CoA Enzymes stop the synthesis of fatty acids, the growth and division of cells cannot be carried out normally, the membrane system and other lipid-containing structures ar...

AI Technical Summary

Problems solved by technology

[0008]Currently, herbicides in wheat fields are limited by crop safety, and their herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control weeds in wheat fields In addition, some herbicides are likely to cause residual toxicity to current crops or subsequent crops due to their high water solubility, long field duration, excessive dosage, or uneven application.
