Abstract

The invention belongs to the technical field of pesticide preparations, and provides a pesticide water-dispersible granule and a preparation method thereof. A pesticide water-dispersible granule, which is composed of the following components in parts by weight: 15-70 parts of pesticide active ingredients, 5-10 parts of dispersant, 2-5 parts of wetting agent, 5.5-9 parts of disintegrating agent, binder 1-4 parts of agent, 2-10 parts of filler, dispersant is a mixture of poloxamer, chitosan and citric acid with a mass ratio of 4:1:1.5. In the preparation method, the active ingredients of the pesticide, the dispersant, and the disintegrating agent are mixed evenly and then pulverized, then mixed with the wetting agent and binder dissolved in water to obtain a suspension, the suspension is spray-dried, mixed with the filler, squeezed Pressing granulation, drying and other steps. Through the above technical scheme, the problems of single formulation and small application range of the water-dispersible granules in the prior art are solved.

Description

technical field

[0001] The invention belongs to the technical field of pesticide preparations, and relates to a pesticide water-dispersible granule and a preparation method thereof. Background technique

[0002] Water-dispersible granules are a new environmentally friendly formulation of pesticides developed in the 1980s, developed on the basis of wettable powders and suspension concentrates. The formulation reduces environmental pollution during processing and use, and is convenient for measurement, packaging and transportation, reducing the cost of farmers' use, which is a major trend in the development of pesticides at present.

[0003] At present, water-dispersible granules are mainly composed of raw materials, dispersants, wetting agents, disintegrants, binders, fillers and other components. The selection of additives affects the wettability and disintegration of water-dispersible granules. The key factors of suspension and suspension, which in turn affect the retentio...
