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.

Abstract

The invention discloses a weeding composition containing clodinafop-propargyl and flucarbazone-sodium and application of the weeding composition. Clodinafop-propargyl and flucarbazone-sodium serve as main effective components of the weeding composition, the mass ratio of clodinafop-propargyl to flucarbazone-sodium is 1-99 to 1-99, and the mass percent of clodinafop-propargyl and flucarbazone-sodium in the weeding composition accounts for 10-80% of the total mass percent. The weeding composition can be used for post-seedling weeding of wheat fields, and especially has a remarkable effect on preventing and killing graminaceous weed and broad-leaved weed in the wheat fields. By means of the weeding composition, compared with single agents, on the premise of improving efficacy, weed resistance is delayed, a weeding spectrum is wide, the lasting period is long, and safety is achieved for wheat and succeeding crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and in particular relates to a binary compound herbicidal composition of clodinafop-propargyl and tricarbazone-methyl, 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 st...
