Abstract

The invention discloses a weeding composition containing isoxaflutole and flufenacet, belongs to the technical field of pesticide mixing, and aims to solve problem that weeds easily generate resistance to the conventional pesticide. The weeding composition disclosed by the invention contains isoxaflutole and flufenacet which serve as effective components; the weight ratio of isoxaflutole to flufenacet is (35:1)-(1:30); the weeding composition further comprises a carrier and an auxiliary. The weeding composition can delay and overcome the drug resistance of the weeds and prolong the acting time of herbicide; the weeding composition is extremely good in coordinative synergism effect; the use amount of pesticide can be reduced, the drug use cost is lowered, and the pollution to the environment is reduced.

Description

technical field [0001] The invention relates to the field of pesticide compounding, in particular to a herbicidal composition of isoxaflutole and flufenacet. Background technique [0002] Isoxaflutole, belonging to isoxazole herbicides, is an organic heterocyclic selective systemic pre-emergence herbicide used for soil treatment in upland crop fields such as corn and sugarcane. Root absorption and conduction work. After sensitive weeds absorb the drug, they destroy the formation of chlorophyll by inhibiting p-hydroxyacetone dioxygenase, resulting in chlorosis and wilting of the affected weeds. [0003] Flufenacet, an aryloxyacetamide compound, inhibits cell division and growth. The primary target site may be the metabolism of fatty acids. Drug resistance is mainly due to the rapid detoxification of glutamine peptide transferase. It can widely control annual grass weeds, sedges and some small broadleaf weeds. Flufenacet is mainly used for soil treatment, pre-emergence or e...
