Problems solved by technology

[0004] From the above analysis, it can be seen that the weeds in cotton fields are mainly broad-leaved weeds at present, but the herbicide species promoted in production mainly control gramineous weeds and are soil treatment agents, and there is no registration in China to effectively control cotton fields. Stem and leaf treatment for broadleaf weeds

Abstract

The invention discloses a phytocidal composite used for cotton crop, which contains the following components: (A) pyrithiobac-sodium (2-chlorin-6 (4, 6-dimethoxy pyrimidine-2-gluthione) sodium benzoate), (B) any of the following weedicides: quizalofop-p-ethyl, fenoxaprop, sethoxydim or clethodim, (C) the balance of addition agent; wherein, the weight ratio of the component (A) and the quizalofop-p-ethyl is 1:8-20:1, the weight ratio of the component (A) and the fenoxaprop, the sethoxydim or clethodim is 1:3-3:1, the weight percentange of the component A + the component B in the composite is 5-70%. The phytocidal composite efficiently expands the weed control spectrum and has better control efficiency to the main grassy weed and the broadleaves in the cotton field.

Description

technical field [0001] The invention belongs to the field of pesticide herbicides, in particular to a herbicide composition for cotton crops. Background technique [0002] Cotton is the main economic crop in my country, and effective control of weeds in cotton fields is one of the important measures to improve cotton yield and quality. According to the survey results of the occurrence of weeds in cotton fields, the weeds in cotton fields are mainly broad-leaved weeds such as quinoa, retroflexus, purslane, and amaranth, which account for about 70% of the total weed occurrence. At present, the herbicides used to prevent and control weeds in cotton fields are mainly soil treatment agents such as acetochlor, pendimethalin, trifluralin, and Jindur, which mainly control gramineous weeds and some broad-leaved weeds. Effectively control crabgrass, goosegrass, and barnyardgrass in cotton fields, but have poor control effects on the main weeds in cotton fields such as quinoa, purslan...
