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

Example Embodiment

[0053] The second aspect of the present invention provides a preparation method of the herbicide adjuvant, which comprises the following steps: adding water, betaine, alkyl glycosides and polyoxyethylene ether type nonionic surfactants to the reaction kettle, and stirring to Mix well and get it.

[0054] The third aspect of the present invention provides the application of the herbicide adjuvant, which is applied to a solution.

[0055] The herbicide adjuvant provided by the invention can significantly reduce the surface tension of the herbicide original drug liquid, has good wetting and permeability, can efficiently penetrate the target, and effectively improves the utilization rate of the original drug, especially glyphosate and glufosinate The synergistic effect of the two types of herbicides is remarkable. In addition, the present invention solves the problems of delamination and turbidity in the process of use and storage of the soluble agent through reasonable proportioning,...

Example Embodiment

[0059] Example 1

[0060] Example 1 provides a herbicide adjuvant, by weight percentage, including the following components: alkyl glycoside 30%, betaine 30%, polyoxyethylene type non-ionic surfactant 5%, water supplement to 100% .

[0061] The alkyl glycoside is a C8-C16 alkyl glycoside, selected from Shanghai Myron Daily Chemical Co., Ltd., model APG-0810; the betaine is dodecyl dimethyl betaine, selected from Shanghai Xuejie Chemical Co., Ltd., model BS-12; the polyoxyethylene type nonionic surfactant is isooctanol polyoxyethylene polyoxypropylene ether, selected from Jiangsu Hai’an Petrochemical Plant, model EH-9; the water is deionized water.

[0062] The preparation method of the herbicide adjuvant includes the following steps: adding water, betaine, alkyl glycoside and polyoxyethylene ether type nonionic surfactant into the reaction kettle, stirring until the mixture is uniform, and then obtaining.

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...
