Abstract
This invention relates to novel biopesticidal compositions comprising an active insecticidal ingredient selected from insecticidal bacteria and viruses such as B. thuringiensis crystal protein or spores or mixtures thereof and baculoviruses such as nuclear polyhedrosis viruses, granulosis viruses and non-occluded viruses; a polymer; and an inorganic light blocking agent wherein the light blocking agent protects the active ingredient from both ultraviolet light and sunlight and the polymer forms a matrix in which the active ingredient and light blocking agent are dispersed therein. Methods for producing the biopesticidal compositions and methods of controlling insects are also included within the scope of the invention.
