Problems solved by technology

The three commonly used soil sealing agents for cotton fields are pendimethalin, acetochlor and trifluralin, and the use cost of pendimethalin is too high; Soil moisture requirements are high; trifluralin is a long-residual herbicide, which is easy to cause crop damage, and must be mixed with soil when used, which is labor-intensive and time-consuming. After use, it will also cause cotton roots to swell

Abstract

The invention discloses an active composition for cotton field weeding, comprising N-phenyl-[2-chlorine-6-(4,6-dimethoxy pyrimidine-2-oxygroup)] benzylamine and pendimethalin. The invention also discloses a cotton field phytocide, comprising the active composition, an acceptable carrier in pesticides and auxiliaries. Compared with the existing cotton field phytocide, the active composite or the phytocide provided by the invention has the advantages of wide herbicidal spectrum, high weeding activity, high crop safety, no antagonism, complementary characteristics and no weed resistance.

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 dinitroaniline 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; Soil moisture requirements are relatively high; trifluralin is a long-re...
