Problems solved by technology

[0006] Clothianidin insecticides for plant protection currently have 50% registered clothianidin wettable powder, because the water-dispersible granules cannot disintegrate and dissolve quickly after being put into water, and can only be dispersed to form a granular suspension, and the utilization rate of active ingredients is low , in general, the utilization rate of active ingredients is about 70%, therefore, developing a clothianidin wettable powder that can meet the above defects has become a technical problem to be solved urgently by those skilled in the art

Abstract

The invention discloses 50% clothianidin wettable powder. The water dispersible granule is prepared from, by mass, 47.5%-52.5% of clothianidin original medicine, 0-10% of a wetting agent, 0-25% of a dispensing agent, 10%-30% of disintegrant and the balance fillers, and the sum of all components is 100%. The water dispersible granule is high in solubility and high in utilization rate.

Description

technical field [0001] The invention relates to a wettable powder, in particular to a 50% clothianidin wettable powder. Background technique [0002] Among pesticide preparations, wettable powders are in increasing demand due to their ease of use, safety, and space-saving properties during transportation, and research has been conducted on the development of wettable powders that incorporate various active ingredients of pesticides; water-dispersible granules Pesticides are usually prepared by adding or mixing auxiliary agents such as wetting agents, dispersants, binders, and bulking agents to the active ingredients of pesticides (pesticides), and granulating them into granules; [0003] Wettable powders are usually diluted with water or suspended to about 10 to 10,000 times. Wettable powders are required to disintegrate and disperse quickly after being put into water. Therefore, various methods for improving disintegration and dispersibility have been proposed. ; If the di...
