Abstract

The invention relates to a weeding composition of bispyribac-sodium and saflufenacil. The weeding composition has a synergetic effect, and the weight ratio of bispyribac-sodium to saflufenacil is (40-100):(2-8), and preferably (60-100):(6-8).

Description

technical field [0001] The invention belongs to the field of herbicide compounding, and specifically relates to a herbicidal composition containing bispyribac and saflufenacil. The application of the herbicidal composition in post-emergence weeding of paddy fields has broad-spectrum, quick-acting and high-efficiency , low toxicity, safety and environmental protection and other advantages. Background technique [0002] Bispyribac-sodium, molecular formula: C 19 h 17 N 4 NaO 8 , chemical name: 2,6-bis(4,6-dimethoxypyrimidinyl-2-oxyl)sodium benzoate. Bispyribac is a benzoic acid herbicide. This product inhibits the synthesis of acetic acid and lactic acid through root and leaf absorption and hinders the biosynthesis of branched chain amino acids. It is a selective herbicide. It is used in direct-seeding rice fields with high efficiency, broad spectrum, and extremely low dosage. After application, the product can be quickly absorbed by the stems and leaves of weeds, and spr...
