Abstract

The invention belongs to the field of pesticides and herbicides, and discloses a cornfield herbicidal composition containing acetochlor, fensulfame and 2,4-D isooctyl. The herbicidal composition includes acetochlor, fenflufe Amine, 2,4‑D isooctyl, the mass ratio of acetochlor, flumesulam and 2,4‑D isooctyl is (10‑80):(1‑50):(1‑50) . The herbicidal composition of the present invention has high efficiency, safety, low residue and low cost, is used for pre-emergence treatment of corn after sowing, is beneficial to the comprehensive treatment of crop weeds, not only expands the herbicidal spectrum, but also has good overall control effect on weeds, and play a synergistic role.

Description

technical field [0001] The invention relates to a herbicidal composition, in particular to a cornfield herbicidal composition containing acetochlor, flumesulam and 2,4-D-isooctyl. Background technique [0002] my country is a big country in corn planting and production, with the sown area ranking first in the world and the total output ranking second in the world. Weeding has always been a difficult problem in the management of corn planting. At present, the most effective and economical method is chemical weeding. However, the long-term continuous use of herbicides with a single species or a single mechanism of action will lead to continuous enhancement of weed resistance and drug resistance. Prevention is becoming more and more difficult. Reasonable compounding or mixing of different types of herbicides can effectively expand the herbicidal spectrum, improve the control effect, and continue the resistance and resistance of weeds. It is one of the most effective methods to...
