Abstract

The invention discloses a pesticide controlled-release carrier as well as a preparation method and application thereof. The pesticide controlled-release carrier comprises a porous structural medium and a surface layer plugging material; the porous structural medium for adsorbing a crude drug of a pesticide is plugged by using the surface layer plugging material; the porous structural medium comprises polylactic acid or aluminum oxide; and raw materials for preparing the surface layer plugging material include hydrocarbonate, a molecular sieve, guar gum, cellulose ether and gelatin. The structure of the pesticide controlled-release carrier is improved, so that the pesticide controlled-release effect is improved; in addition, no novel pollution sources are introduced; and the invention discloses the preparation and use methods of the pesticide controlled-release carrier.

Description

technical field [0001] The invention relates to the field of pesticide mixtures, in particular to a pesticide slow-release carrier and its preparation method and application. Background technique [0002] Pesticide refers to a general term for a class of drugs used to kill insects, bacteria, and kill harmful animals (or weeds) in order to ensure and promote the growth of plants and crops in agricultural production. In the processing or use of pesticide preparations, in order to achieve the purpose of improving drug efficacy and facilitating transportation and storage, it is necessary to use pesticide carriers. Common pesticide carriers include: wetting agents, emulsifiers, dispersants, adhesives, stabilizers, synergists, and slow-release agents. [0003] In order to facilitate the transportation and long-term storage of pesticides, and to slowly release and prolong the efficacy of pesticides, it is necessary to use slow-release agents to combine pesticides. And in order to...
