Abstract:
A method of delivering a pest control agent to a target organism, comprising:applying to at least a portion of a surface of a substrate selected from a plant, a man-made structure, and stored grain, an effective amount of finely divided particulate material at least partially coated with the pest control agent, the particulate material comprising from about 25% to about 100% by weight of a heat treated particulate material, the heat treated particulate material heated to a temperature from about 400Â° C. to about 1,200Â° C. for a time from about 10 seconds to about 24 hours, wherein the partially coated finely divided particulate material as applied permits an exchange of gases on the surface of the substrate and the partially coated finely divided particulate material forms a continuous film over the portion of the substrate surface to which it is applied, and a maximum average size of openings in the continuous film is less than about 100 &mgr;m.
