Pesticide compositions exhibiting enhanced activity and methods for preparing same

摘要

Pest controlling compositions exhibiting enhanced pesticidal activity levels and methods for preparing the same are disclosed. In one embodiment, a method includes providing a liquid composition that includes at least one pesticide and at least one co-ingredient that enhances pesticidal activity of the composition compared to a composition dissimilar only in not having the at least one co-ingredient. The at least one co-ingredient may include at least one metal oxide, a combination of at least one transition metal salt and at least one proteinaceous material or a combination of at least one proteinaceous material and at least one polymeric material. The method further includes spray drying the liquid composition to provide a solid composition. In one aspect of this embodiment, the solid composition provided by the spray drying exhibits enhanced pesticidal activity compared to the liquid composition.
