Abstract

The invention relates to the technical field of pesticides, in particular to a weeding composition, a preparation and a preparation method and application thereof. According to the weeding composition, the weeding composition comprises an active component A and an active component B, the active ingredient A is saflufenacil; and the active component B is selected from at least one of butachlor, pretilachlor, acetochlor, metolachlor, anilofos, pendimethalin, butralin, benthiocarb, bensulfuron methyl, pyrazosulfuron methyl and cyclosulfamuron. The weight ratio of the active component A to the active component B is 1: (0.02-50). The weeding composition provided by the invention can be used after rice sowing and before seedling, and can effectively control the growth of weeds, reduce the dosageand cost, improve the weeding effect and delay the generation of resistance; meanwhile, by optimizing the auxiliary agent, the prepared suspoemulsion has relatively good physical stability.

Description

technical field

[0001] The invention relates to the technical field of pesticides, in particular to a herbicidal composition, preparation, preparation method and application thereof. Background technique

[0002] The herbicide varieties containing a single active ingredient have different degrees of defects in the agricultural weeding process: continuous use is easy to produce resistance, the herbicidal spectrum is not wide enough, and it can only control monocotyledonous or dicotyledonous weeds, or can only control emerging weeds. Weeds or unemerged weeds cannot be controlled at the same time. Through the compounding of two or more active components, the control effect can be improved, the usage of active components can be reduced, the cost of control can be saved, the emergence of weed resistance can be delayed, the service life of the pesticide can be extended, and the pollution to the environment can be reduced.
