Abstract

The invention discloses a cyhalothrin water emulsion insecticide with low skin irritation and a preparation method thereof. The cyhalothrin water emulsion insecticide comprises a wetting agent, a dispersant, a thickening agent, a defoamer, an antifreezing agent, a preservative, a regulator and the balance of water. The wetting agent and the dispersing agent are self-developed according to the characteristics of the formula. In addition, the invention further discloses a preparation method of the cyhalothrin water emulsion insecticide with the low skin irritation effect. The water emulsion agent provided by the invention has the advantages of being capable of being uniformly mixed and dispersed with water in any proportion, good in flowability, capable of regulating crop activity and improving pesticide effect, free from the influence of water quality and water temperature, convenient to use, not easy to pollute the environment and capable of being diluted and sprayed. By adjusting theproportion of all the components, the water emulsion has a good sterilization effect, plant growth can be properly adjusted, and harm to crops and human bodies is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of plant fungicides, and in particular relates to a cyhalothrin water-emulsion insecticide which not only has a good bactericidal effect but also can properly regulate plant growth and a preparation method thereof. Background technique [0002] Cyhalothrin, chemical name: 1-(4-chlorophenoxy)-1-(1H-1,2,4-triazol-1-yl)-3,3-dimethyl-butan-2 -alcohol, cyhalothrin is a low toxicity broad spectrum insecticide. It is used to control wheat, rice rust, powdery mildew, sheath blight and other diseases, and has obvious effect of increasing yield. It can also be used as a treatment agent for cereal seeds and to prevent and control cereal head smut. [0003] In China, cyhalothrin is mainly marketed as wettable powder and emulsifiable concentrate. Since wettable powders are prone to dust pollution during processing and use, and the water-emulsion rate of wettable powders is lower than that of water-emulsions, the produ...
