Abstract
Insecticidal pellet compositions of N-hydrocarboyl phosphoroamidothioates and phosphoroamidodithioates are provided. These compositions have improved odor control, thermal stability, attrition resistance, bulk density and handling characteristics over the powdered forms of the insecticides. Methods are provided for making such pellets, and in particular, an extrusion method is provided in which the dry insecticidal composition is mixed with from 3-25% of a solvent to form a consistency of damp sandy loam and then extruded.
