Complex herbicide

Abstract

The invention belongs to the technical field of pesticide, and relates to a complex herbicide. The complex herbicide is characterized by containing two active ingredients, fenoxasulfone and pyriminobac-methyl, which are supplemented with auxiliary agents and prepared into a dispersible oil suspending agent and a suspending agent. The complex herbicide is used to control annual gramineous weeds and broadleaf weeds in rice paddies, and has the advantages of wide herbicidal spectrum, significant weeding effect, environment-friendliness, and obvious synergistic effect.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a compound herbicide containing fenoxasulfuron and pyriflubac-methyl. Background technique [0002] Fenoxasulfone (fenoxasulfone) belongs to dimethoxytriazine-substituted difluoromethanesulfonyl aniline herbicides. It has a good control effect on grasses and broad-leaved weeds, and has a good effect on rice and barnyard grass. It has high selectivity and has good control effect on barnyard grass from germination to three-leaf stage. The structural formula is as follows: [0003] [0004] Pyriminobac-methyl is a systemic conduction-type professional barnyardicide recently developed by Japanese Combinatorial Chemicals. It belongs to pyrimidine salicylic acid herbicides. It can be absorbed through the stems, leaves and roots of weeds and quickly conducts To the whole plant, it inhibits the biosynthesis of acetolactate synthase (ALS) and amino acids, thereby inhibi...
