Problems solved by technology

Once drug resistance occurs, the recommended dosage cannot effectively control the target, and the application rate will continue to increase. As a result, weed resistance may increase and fall into a vicious circle of drug resistance
Moreover, the herbicide with a single active ingredient has a limited herbicidal spectrum and cannot effectively control the occurrence of weeds

Abstract

The invention discloses a weeding composition containing halauxifen-methyl and pyribenzoxim and application of the weeding composition. The weeding composition comprises an active component A and an active component B, the active component A is halauxifen-methyl, and the active component B is pyribenzoxim. The mass ratio of the active component A to the active component B of the weeding composition is 1: 50-50: 1. According to the weeding composition, the two effective components, namely the halauxifen-methyl and the pyribenzoxim, with different action mechanisms are combined and compounded for use so that the components have an obvious synergistic effect, the weed control effect is improved, the dosage is reduced, the cost is saved, the generation of weed resistance can be delayed, and the environmental pollution is reduced.

Description

technical field [0001] The present invention belongs to the technical field of pesticide compounding, and in particular relates to a herbicidal composition containing flupyridinate and saflufenacil, and extends to the growth sites and / or leaves and / or Application on stems, especially for weed control in paddy fields. Background technique [0002] Florpyrauxifen-benzyl is a new type of aromatic picolinic acid herbicide developed by Dow AgroSciences, which can be applied to direct-seeded rice fields, transplanted fields and other crop fields. The product has a broad herbicidal spectrum and can effectively control grass weeds, broadleaf weeds and sedge weeds in paddy fields. The CAS accession number is 1390661-72-9. [0003] Pyribenzoxime is a pyrimidine salicylate, broad-spectrum selective post-emergent herbicide. The mechanism of action is similar to that of sulfonylurea and imidazolidone herbicides, and both belong to acetolactate synthase (ALS) inhibitors. It can be use...
