The invention discloses a preparation method and application of a gel drug-loading system with pesticide molecule hymexazol as a gelling agent, wherein the preparation method comprises the following steps: step A: placing carboxymethyl chitosan CMCS and sodium alginate SA in the same container, adding water, and stirring until completely dissolving to obtain a mixed solution CA; and B: preparing hymexazol into hymexazol solution Hy; and C: and mixing the mixed solution CA and the hymexazol solution Hy, and uniformly stirring to obtain a hydrogel drug-loading system. The application of the pesticide molecule hymexazol as a gel drug-loading system of a gelling agent comprises the following steps: the gel drug-loaded system prepared by the preparation method is used for loading pesticide active ingredients. The hymexazol hydrogel drug-loading system prepared by the invention can enhance the adhesiveness of hydrophilic pesticide hymexazol at a target part, fully exert the atom economy of a carrier material, and reduce the loss of pesticide caused by rain wash and the like, thereby improving the utilization rate of the drug. |
