Weeding compound containing 2-methyl-4-chloro-phenoxyacetic acid and oxaziclomefone

Abstract

The invention discloses a weeding compound containing 2-methyl-4-chloro-phenoxyacetic acid and oxaziclomefone. The compound comprises the active component of 2-methyl-4-chloro-phenoxyacetic acid or a derivative of 2-methyl-4-chloro-phenoxyacetic acid and oxaziclomefone. The weight ratio of 2-methyl-4-chloro-phenoxyacetic acid to oxaziclomefone ranges from 60:1 to 1:60. The compound can be applied to the crop weeding aspect in the agricultural field. Experiment results show that the weeding compound is obvious in synergism, can reduce the use amount, and reduces prevention cost. The insect-killing compound can effectively remove various kinds of weeds. By combining weeding agents according to different action mechanisms and action modes, the application amount of each single dosage is effectively reduced, and the compound plays an important role in the aspects of widening weeding spectra, delaying insecticide resistance and the like.

Description

technical field [0001] The invention relates to a herbicidal composition with improved performance, in particular to a herbicidal composition comprising dimethyltetrachloride or its derivatives and oxaziclozone, and belongs to the field of pesticide formulations and applications. Background technique [0002] The application of chemical herbicides is the most effective means of weed control in farmland. However, long-term continuous high-dose use of chemical herbicides with a single variety or mode of action may easily cause problems such as herbicide residues, environmental pollution, and weed resistance and resistance development. Reasonable compounding or compounding of chemical herbicides can expand the spectrum of weeds, improve the control effect, prolong the application period, reduce the dosage, reduce the injury, reduce the residue, and delay the occurrence and development of weed resistance and drug resistance It is one of the most effective ways to solve the abov...
