Bensulfuron methyl-isoproturon herbicide and production method thereof

Abstract

The invention relates to a herbicide and a production method thereof, and particularly discloses a bensulfuron methyl-isoproturon herbicide and a production method thereof. The herbicide is prepared from, by weight, 1%-80% of bensulfuron methyl, 15%-85% of isoproturon, auxiliaries, 2%-18% of a dispersing agent and the balance packing, wherein the auxiliaries comprise, by weight, 0.5%-12% of a wetting agent, 0.3%-14% of an emulsifying agent and 0.4%-8.5% of a safener. Accordingly, due to the fact that the wetting agent, the dispersing agent and the emulsifying agent are simultaneously added, the ingredients with the different effects jointly achieve the effect with the safener, the safener can effectively act, and meanwhile the safener has no influence on metabolism of the herbicide.

Description

technical field [0001] The invention relates to a herbicide and its production method. The herbicide is composed of original medicine, auxiliary agent, dispersant and filler components. Background technique [0002] Isoproturon is the main pesticide used to weed weeds in wheat fields in my country, and it has excellent control effect on weeds in wheat fields. Patent 99114323.X is a herbicide product made by mixing ordinary isoproturon and bensulfuron-methyl with general adjuvants. Bensulfuron-methyl is a herbicide used to control broad-leaved weeds, and it is basically ineffective against monocotyledonous weeds; It is acceptable for weeding in wheat fields, but for weeding in paddy fields, it was first discovered by "Qian Yongkang", but the safety factor of the original combination is small, and it is not safe to use in paddy fields, especially direct-seeding paddy fields, and it is easy to damage crop seedlings if it is accidentally applied. Even dead seedlings, so the pra...

Patent 99114323.X is a herbicidal product made by mixing ordinary isoproturon and bensulfuron-methyl with general adjuvants. Bensulfuron-methyl is a herbicide used to control broad-leaved weeds, and it is basically ineffective against monocotyledonous weeds; It is acceptable for weeding in wheat fields, but it was first discovered by "Qian Yongkang" for weeding in rice fields. However, the safety factor of the original combination is small, and it is not safe to use in rice fields, especially direct-seeding rice fields. Careless application can easily damage crop seedlings Even dead seedlings, so the practicability and adaptability are not good enough
