Active composition for weeding in cotton field and weedicide

Abstract

The invention discloses an active composition for weeding in a cotton field, which contains N-phenyl-[2-chloro-6-(4,6-dimethoxy-pyrimidine-2-oxy)] benzylamine and acetochlor. The invention also discloses a weedicide for the cotton field. The active composition and the weedicide have the advantages of wide weedicide spectrum, high weeding activity, high crop safety, no antergic action, complementation of action property, non-resistance of weed and the like.

Description

technical field [0001] The invention relates to an active composition for weeding in cotton fields, in particular to a herbicide composition for controlling weeds in cotton fields compounded by pyrimidine benzylamine herbicides and chlorinated amide herbicides and its application. Background technique [0002] my country is the largest cotton producer in the world, and the current cotton planting area and total output account for about 1 / 4 of the world. The herbicides used in cotton fields mainly include pre-sowing and post-sowing pre-emergence soil treatment agents and stem and leaf treatment agents. The cost of using stem and leaf treatment agents is generally high, so soil treatment agents are mainly used for weeding in cotton fields in my country. The three commonly used soil sealing agents for cotton fields are pendimethalin, acetochlor and trifluralin, and the use cost of pendimethalin is too high; The requirement for soil moisture is relatively high; trifluralin is ...
