Problems solved by technology

However, there is a waxy layer or fluff on the surface of the plant, which will affect the plant's absorption of exogenous substances and defense against the invasion of exogenous harmful substances, mainly because the waxy layer or fluff layer forms a hydrophobic and low-energy surface, which is not conducive to the liquid on the plant surface. Wetting and penetration, thus affecting the osmotic absorption and utilization of herbicides
[0004] The results of a large number of field drug efficacy tests show that if the agent has poor adhesion and cannot quickly wet and penetrate the target after spraying in the field, more than 30% of the agent will be lost and volatilized, causing pollution to the atmosphere, soil, water quality and even the entire ecological environment; and the existing The herbicide adjuvants have defects such as poor performance, immature technology, large differences between batches, extremely unstable performance, easy delamination and crystallization when compounded with pesticides, which seriously affect the normal use of pesticides in the production and processing process.

Abstract

The invention relates to the technical field of pesticide auxiliaries, in particular to a herbicide auxiliary agent and a preparation method thereof. The herbicide auxiliary agent at least comprises the following components in percentage by weight: 5-30% of a polyoxyethylene type nonionic surfactant, 20-40% of betaine, 20-40% of alkyl glycoside and the balance of water, totaling 100%. The herbicide auxiliary agent provided by the invention is an environment-friendly auxiliary agent, no three wastes are generated in the production process, and the preparation raw materials are low-toxicity or non-toxic substances, are easy to biodegrade and do not cause harm to the ecological environment; secondly, the herbicide auxiliary agent provided by the invention can significantly reduce the surfacetension of a liquid medicine, has good wetting permeability, efficiently permeates a target, and especially has an obvious synergistic effect on glyphosate and glufosinate-ammonium herbicides.

Description

technical field [0001] The invention relates to the technical field of pesticide adjuvants, in particular to a herbicide adjuvant and a preparation method thereof. Background technique [0002] The "pesticide" that people often say actually refers to the pesticide preparation that is sold as a commodity and can be used directly. Pesticide preparations are composed of pesticide active ingredients and auxiliaries, among which the original pesticide is the functional active ingredient. The proportion of pesticides in pesticides is often as high as 80%. As my country's emphasis on environmental protection continues to increase, traditional formulations such as emulsifiable concentrates and powders in the pesticide industry will gradually be restricted, and then environmentally friendly water-based formulations such as suspension concentrates, water-emulsions, solubles, and microemulsions will be introduced. replaced. [0003] Herbicides can be divided into contact type and sys...
