AI Technical Summary

Problems solved by technology

[0003] Due to historical reasons and low cost, conventional highly toxic pesticides such as organophosphorus, carbamate, and organochlorine in my country do not add synergists to most of the highly toxic pesticides. The surface activity is low and the surface tension of the solution is large.
It is difficult to form a strong protective film on the surface of the agent emulsion and aqueous solution droplets, and the wetting distribution and adhesion of the agent on the surface of the plant or pest are poor, and the amount of pesticide is relatively large.

Embodiment 1

[0025] Embodiment 1 formula:

[0026] 15% of tea saponin, 1% of fatty amine, and the rest is water, and all percentages are percentages by weight.

Embodiment 2

[0027] Embodiment 2 formula:

[0028] Tea saponin 15%, fatty amine 3%, the rest is water, and all percentages are percentages by weight.

[0029] The production method of the present invention is to mix tea saponin, fatty amine and water according to the above formula to obtain the product.

[0030] The production method of the tea saponin in the present invention is as follows: the camellia oleifera cake is extracted with water-containing methanol in the extraction kettle, the extract is filtered through micropores, and the methanol is recovered to obtain 50% crude tea saponin, and the crude tea saponin is repeatedly washed three times with absolute ethanol , through the basic macroporous adsorption resin to separate pigments, crude protein and other impurities, recover methanol, concentrate, and dry to obtain tea saponin with a content of 95%.

[0031] The technical index of the agricultural pesticide synergist made according to embodiment 2 is as follows:

Abstract

A dual-activity synergist for agricultural chemical is prepared from tea saponin and fatty amine, and has features of its dual functions of reducing the consumption of agricultural chemical by 30-50% and promoting the health growth of plant. Its advantages are high biodegradation speed, high effect and low cost.

Description

Technical field: [0001] The invention relates to the field of pesticide adjuvants, which is a pesticide synergist produced by natural plants with both surface activity and biological activity. technical background: [0002] Pesticide adjuvants are the general term for all kinds of adjuvants used in chemical pesticide processing formulations except active ingredients. The adjuvant itself has no biological activity, but it is an indispensable additive in the formulation of new formulations or in the application of pesticides. The main purpose of adding adjuvants is to improve drug efficacy, reduce the amount of pesticides, save costs, reduce pesticide residues on crops and pollution of the environment. [0003] Due to historical reasons and low cost, conventional highly toxic pesticides such as organophosphorus, carbamate, and organochlorine in my country do not add synergists to most of the highly toxic pesticides, which have low surface activity and high surface tension of ...
