Problems solved by technology

Chemical method of weeding is one of the main means of controlling weeds in paddy fields. Weeds in paddy fields have complex grass phases, mixed grasses, broad-leaved weeds, Cyperaceae and other types of weeds, and a single herbicide is used Can not solve the weeds in paddy fields, all will show some defects and limitations

Abstract

The invention discloses a paddy field weeding composition containing florpyrauxifen. The paddy field weeding composition includes florpyrauxifen, pyribenzoxim, bensulfuron methyl and pesticide auxiliary components; the mass ratio of florpyrauxifentopyribenzoximtobensulfuron methylwhich serve as effective components of the weeding composition is 1-25 to 1-30 to 2-40, preferably, the mass ratio is 1:3:5, and the total quantity of the effective components is 5%-80% of that of the weeding composition. The paddy field weeding composition has a synergistic effect and is mainly used for being sprayedto stems and leaves in paddy direct seeding fields and transplanting fields to prevent and remove annual weeds and perennial weeds. Gramineae weeds such as barnyard grass and leptochloa chinensis, cyperaceae weeds such as cyperus difformis, cyperus iria and cyperus rotundus and broadleaf weeds such as monochoria korsakowii, sagittaria trifolia and xanthium sibiricum patrinin the paddy fields canbe effectively prevented and removed. The prevention and removing effects of the paddy field weeding composition are obviously better than those of single-component agents, the synergistic effect is significant, and the paddy field weeding composition has the advantages of being high in weeding activity, wide in weeding spectrum, high in paddy safety and the like and is an environment-friendlyherbicide.

Description

technical field [0001] The invention belongs to the pesticide herbicidal composition, and specifically relates to a paddy field herbicidal composition containing halopyridine. Control annual and perennial weeds in paddy fields. Background technique [0002] Weeds are an important part of the agricultural ecosystem, competing with crops for glory, fertilizer, and water, which is one of the important factors affecting crop growth and resulting in yield reduction. Rice is one of the main food crops in my country, and rice is the staple food of about 60% of the population in the country, so the increase or decrease of rice production has a decisive impact. Chemical method of weeding is one of the main means of controlling weeds in paddy fields. Weeds in paddy fields have complex grass phases, mixed grasses, broad-leaved weeds, Cyperaceae and other types of weeds, and a single herbicide is used Can not solve the paddy field weeds, all can show the defect and limitation of certa...
