Abstract

Disclosed in the present invention is a weeding composition having synergistic effects, and in particular a herbicide composition for effectively preventing and removing weeds. The composition comprises a component A and a component B, where component A is diflufenican and component B is pyribenzoxim. Pharmacodynamic tests show that the composition has positive characteristics of strong complementarity, obvious synergistic effect, increased weed control spectrum, reduced application amount, prolonged appropriate application time, high crop safety, reduced environmental pollution, good environmental compatibility, and the like.

Description

technical field [0001] The present invention belongs to the field of agricultural plant protection, and in particular relates to a herbicidal composition with improved properties. Background technique [0002] Active ingredient diflufenican (diflufenican) This drug belongs to the class of carotenoid biosynthesis inhibitors. Cause chlorophyll damage and cell rupture, plant death. Diflufenican is an amide herbicide, applied before or after weed germination can form a leaching-resistant medicinal soil layer on the soil surface, and maintain activity throughout the growing season of the crop. When the weeds germinate through the medicinal soil layer, the young shoots or roots can absorb the drug. Diflufenican can inhibit the biosynthesis of carotenoids. The content of carotenoids in the weed plants that absorb the drug decreases, resulting in the destruction of chlorophyll and the rupture of cell membranes. , the weeds show that the young shoots are decolorized or white, and f...
