Application of polyether compound as synergist of herbicide

Abstract

The invention relates to application of a synergist of a herbicide, in particular to application of a polyether compound as the synergist of the herbicide, and belongs to the technical field of pesticides. According to the application of the R1O(CH2CHOH)nR2 or the salt of the R1O(CH2CHOH)nR2 serving as the synergist of the herbicide, R1 is alkyl or phenolic group; R2 is-H,-O (CH2CHOH) mH or-O (CH2CH2CHOH) mH; and n is 1 to 50, and m is 1 to 50. The weeding composition has the advantages of reducing the use amount of other herbicides, reducing the use amount of chemical pesticides, increasing the weeding effect and the effect of preventing and removing resistant weeds, and is safe to the environment.

Description

technical field [0001] The invention relates to the use of a herbicide synergist, in particular to the use of a polyether compound as a herbicide synergist, and belongs to the technical field of pesticides. Background technique [0002] In the new environment, the requirements for environmental protection and safety are getting higher and higher. The extensive use of chemical herbicides leads to increased weed resistance, and weeds are becoming more and more difficult to control, resulting in increased use costs, and the development of new herbicides costs even more . Moreover, the extensive use of many chemical herbicides has caused certain pollution to the environment. [0003] Polyether is currently the largest selling synthetic oil. It is a linear polymer prepared by ring-opening homopolymerization or copolymerization with ethylene oxide, propylene oxide, butylene oxide, etc. as raw materials under the action of a catalyst. Generally, it has a lower freezing point, be...
