Abstract

The invention relates to a soluble granule capable of being used for preventing and treating agricultural pest. The soluble granule consists of a high molecular material, a pesticide active ingredient, a wetting agent and a soluble carrier material, wherein the pesticide active ingredient is a water-insoluble or water slightly soluble pesticide active ingredient; and the soluble granule is processed through processes such as hot melting or solid dispersion. The prepared preparation product provided by the invention has the advantages that the dispersion degree and the bioactivity of the active ingredient are higher than those of missible oil, suspension and wettable powder formulations when the preparation is prepared into liquor for application. Meanwhile, compared with a missible oil product, the hazard levels of leakage, combustion and explosion of the soluble granule under normal temperature are greatly reduced; and compared with wettable powder and suspension formulations, air stream crushing or sand milling is not required in a production process, the production efficiency is high, less dust is provided, the production process is clean, and the package and the transportation are convenient.

Description

technical field [0001] The invention relates to an insecticidal and bactericidal soluble granule and a production method, through which the granule product is obtained and its application in agriculture. Background technique [0002] Commonly used pesticide formulations, such as powders, wettable powders, emulsifiable concentrates, suspension concentrates, etc., after use, the active ingredients are fully exposed in the natural space, and highly toxic agents can easily cause poisoning and kill beneficial organisms. In addition, due to photolysis, hydrolysis, biodegradation or water leaching loss, air volatilization and other reasons, the loss rate of the pesticide agent is as high as 60%-90% by weight, and the field duration of the agent is also greatly shortened. [0003] And because some original medicines are unstable in water and consider processing, packaging storage and transportation and use technical requirements, if can not be processed into water-based dosage forms...
