Herbicidal composition

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 penoxsulam, which are supplemented with auxiliary agents and prepared into a dispersible oil suspending agent and suspending agent. The herbicidal composition 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, in particular to a herbicidal composition containing fenoxasulfuron and penoxsulam. Background technique [0002] Fenoxasulfone belongs to dimethoxytriazinyl-substituted difluoromethanesulfonyl aniline herbicides, and has a good control effect on gramineous and broad-leaved weeds, especially barnyardgrass, Annual broad-leaved weeds such as Yujiuhua and Motherweed have high selectivity to rice and barnyard grass, and have good control effects on barnyard grass from germination to three-leaf stage. The structural formula is as follows: [0003] [0004] Penoxsulam is a post-emergence herbicide developed by Dow AgroSciences in the United States. It is a triazolopyrimidine sulfonamide herbicide and works by inhibiting acetolactate synthase (ALS). . Penoxsulam is a conductive herbicide, which is absorbed by stems, leaves, young shoots and roots, and then transmitted to meristems through xylem ...

Problems solved by technology

Field experiments have shown that long-term use of a single herbicide is not only prone to resistance and phytotoxicity, but also has a greater impact on the soil environment
