Abstract

The present invention relates to a pesticide herbicide product, in particular to a dispersible oil suspension containing penoxsulam, saflufenacil, and cloclofenac and a preparation method thereof, wherein the distribution ratio of each component is: penoxsulam Amine 2%~8%, saflufenacil 2%~8%, cloclofenac 0.5%~3%, dispersant 1%~8%, emulsifier 5%~15%, wetting agent 0.5%~5% , 0.5% to 5% thickener, 0.5% to 8% stabilizer, 0.2% to 2% defoamer, 0.1% to 2% pH regulator, and the balance is oil-based solvent. Compared with the prior art, the penoxsulam, saflufenacil, and clofenac-ethyl dispersible oil suspension concentrate of the present invention have low toxicity to humans, animals, and beneficial organisms, can reduce the toxicity of active ingredients to applicators, and reduce the The phytotoxicity of drugs on target crops improves the control effect of herbicide products on weeds and the safety of crops. It is a low-carbon, environmentally friendly, safe and efficient dosage form.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a herbicide product, in particular to a dispersible oil suspension containing penoxsulam, saflufenacil and gluclofenapyr and a preparation method thereof. Background technique [0002] Penoxsulam, chemical name 2-(2,2-difluoroethoxy)-N-(5,8-dimethoxy(1,2,4)triazole-(1,5-C ) pyrimidin-2-yl)-6-trifluoromethyl-benzenesulfonamide. It is a herbicide for post-emergence paddy fields developed by Dow AgroSciences. It was officially registered with the US EPA on September 24, 2004. It was promoted and applied in the southern rice fields of the United States in 2005, and it was registered in my country in 2008. It is a conductive strong acetolactate synthase inhibitor. The drug is absorbed by the stems, leaves, buds and roots, and then transmitted to the meristematic tissue through the xylem and phloem, inhibiting plant growth, making the growing point chlorotic, and weeds for 7-15 days...
