Problems solved by technology

[0004] However, clethodim degrades quickly, and the half-life of the original drug is 0.7 months at 50°C; the clethodim EC currently on the market has a high decomposition rate during storage, about 11%-20%, and the thermal storage test decomposes more severely. Seriously affect the efficacy of the drug

Abstract

The invention belongs to the technical field of pesticide preparations, and particularly relates to clethodim emulsifiable concentrate and a preparation method thereof. The clethodim emulsifiable concentrate is prepared from the following raw materials in percentage by mass: 12 to 24 percent of clethodim, 61 to 73 percent of an organic solvent, 5 to 15 percent of an emulsifier and 5 to 10 percentof a stabilizer, wherein the stabilizer is N,N-disulfoxide salicyl-1,3-diaminopropane; the N,N-disulfoxide salicyl-1,3-diaminopropane is adopted as the stabilizer and is interacted with other components, so that the problem of high decomposition rate of clethodim after being stored is solved; in addition, properties of the clethodim emulsifiable concentrate are stable, so that the problems of layering and depositing to form crystal in the storage process are avoided; besides, the clethodim emulsifiable concentrate can be widely used for herbicides.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparations, in particular to a clethodim emulsifiable concentrate and a preparation method thereof. Background technique [0002] The production of herbicides has continued to maintain a strong growth trend in my country in recent years, and the growth rate far exceeds that of other types of pesticides. The proportion of herbicides in pesticides is also close to 50%. The area of ​​chemical weeding is increasing at a rate of 30 million mu per year. At present, it has reached 600 million mu times, and the herbicide market will expand to more than 70% of the national pesticide market in the next few years. [0003] Clethodim is a cyclohexenone systemic conduction stem and leaf treatment agent, which has a strong killing effect on grass weeds. It is a new type of dry field post-emergence herbicide with excellent selectivity; it has a remarkable control effect on grass weeds. After application, it ...
