Abstract
Novel insecticides are disclosed having improved persistency. Association of certain type B gelatins with microencapsulated insecticides especially those employing polyamide polyurea subunits in the microcapsule walls, yields such persistency. According to a preferred embodiment, PENNCAP M, which is Pennwalt Corporation's trademark for its microencapsulated methyl parathion, is admixed with type B gelatin having average molecular weights between about 15,000 and 30,000 in a sprayable, aqueous, formulation. This formulation protects, for example, crops from insect attack for a longer period than does unmodified PENNCAP M formulations.
