Abstract

The invention discloses a compound weeding composition containing clodinafop-propargyl and triasulfuron and application thereof. The weeding composition takes clodinafop-propargyl and triasulfuron as main effective constituents, the mass ratio of clodinafop-propargyl to triasulfuron is (1-99): (1-99), and the total mass percentage composition of the clodinafop-propargyl and triasulfuron in the weeding composition is 10-80%. The weeding composition disclosed by the invention can be used for post-seedling weeding in wheat fields, and has obvious effect for preventing and removing grassy weeds and broadleaf weeds in the wheat fields particularly. According to the weeding composition disclosed by the invention, under the precondition that the pesticide effect is improved compared with a single dosage, the resistance in weeds is delayed, the weeding spectrum is wide, the lasting period is long, and the weeding composition is safe for both 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 specifically relates to a binary compound herbicidal composition of clodinafop-propargyl and trisulfuron-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 stru...
