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 an herbicidal composition comprising clodinafop-propargyl and fluorochloridone, and an application thereof. According to the herbicidal composition, clodinafop-propargyl and fluorochloridone are main effective components with a mass ratio of 1-99:1-99. The total mass percentage content of the two in the herbicidal composition is 10-80%. The herbicidal composition provided by the invention can be used in wheat field postemergence weed control, and especially has a significant effect in controlling wheat field grassy weeds and broadleaf weeds. Compared to single agents, with the herbicidal composition, the efficacy is improved, weed resistance is retarded, the herbicidal spectrum is wide, and effect duration is long. The herbicidal composition is safe to wheat and next crops.

Description

technical field [0001] The invention belongs to the technical field of pesticides, especially the field of herbicides, and in particular relates to a binary compound herbicidal composition of clodinafop-propargyl and fluroxidone, 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 are d...
