Abstract

The invention discloses a pyribenzoxim-containing weeding composition. The pyribenzoxim-containing weeding composition comprises 1-20wt% of cyhalofop-butyl, 1-20wt% of pyribenzoxim, 1-30wt% of bensulfuron methyl and the balance an herbicide assistant. The pyribenzoxim-containing weeding composition is used for preventing and removing annual weeds in the paddy field, has weeding effects obviously superior to those of single-component weeding agents, has a wide weeding spectrum, improves real effects, delays production of herbicide resistance of weeds and saves time and labor.

Description

technical field [0001] The invention belongs to the pesticide herbicidal composition, in particular to a herbicidal composition containing saflufenacil, which uses cyhalofop-ethyl, saflufenacil and bensulfuron-methyl as active ingredients, and is used for controlling annual weeds in paddy fields . Background technique [0002] Chemical method of weeding is one of the main means of controlling weeds in paddy fields. Weeds in paddy fields have complex grass phases, grass weeds, broad-leaved weeds, sedges and other weeds are mixed, and the use of a single herbicide cannot solve the weeds in paddy fields, and all of them will show some defects and limitations. Through the scientific mixing of different types of herbicides, it has the advantages of improving the weeding spectrum, improving the actual effect, and saving time and labor. [0003] Cyhalofop-ethyl is a variety of aryloxyphenoxypropionic acid herbicides with high safety to rice. Cyhalofop-ethyl is also a systemic c...
