Latest Patents
Among his latest patents is the invention of microencapsulated pyrethroids. This innovation involves a sprayable insecticidal composition that boasts low fish toxicity. The composition consists of a mixture in water of microcapsules containing a pyrethroid, which is a synthetic form of pyrethrin, encapsulated within a cross-linked polymeric material. This invention provides methods of preparation and application for a wide variety of crops and aquatic sites infested with undesirable insects. Another significant patent is for microencapsulated naturally occurring pyrethrins. This process involves microencapsulating naturally occurring pyrethrins with a polyamide-polyurea shell through interfacial condensation. The method requires the slow addition of an amine reactant to an aqueous emulsion containing the pyrethrin, an isocyanate, and an acyl halide, ensuring that at least one of these components is polyfunctional. This results in free-flowing capsules that effectively encapsulate the natural pyrethrin.
