Abstract The low utilization rate of pesticides makes the migration of pesticides in water and soil, which brings great harm to the ecosystem. The development of pesticide carriers with good drug loading capacity and release control ability is an effective method to realize effective utilization of pesticides and reduce pesticide losses. In this work, fosthiazate-stearic acid/expanded perlite sustained-release particles were successfully prepared by vacuum impregnation using expanded perlite (EP) as carrier, fosthiazate (FOS) as model pesticide and stearic acid (SA) as hydrophobic matrix. The structure and morphology of the samples were studied by BET, FT-IR, TGA, XRD, DSC and SEM. The… More >
