Abstract

The invention discloses a herbicidal composition containing saflufenacil, which comprises cyhalofop-ethyl, saflufenacil, bensulfuron-methyl and pesticide adjuvants. The weight percentage of cyhalofop-methyl in the composition is 1%-20%, the weight percentage of saflufenacil in the composition is 1%-20%, and the weight percentage of bensulfuron-methyl in the composition is 1% ~30%, and the rest are pesticide adjuvants. The herbicidal composition of the present invention is suitable for controlling annual weeds in paddy fields, and the weed controlling effect is obviously better than that of any single agent, and has the advantages of wide weeding spectrum, improved actual effect, delayed weed drug resistance, saving time and labor, and the like.

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...
