Abstract

See full text

A method for producing agriculturally active substances such as pesticides to provide improved resistance to environmental degradation, especially heat and ultra-violet light. The method involves the direct reaction of an active protein toxin of a biologically derived pesticide with a UV protectant to form a stable complex having the UV protectant as an integral part of its structure. The method employs lignosulfonates, such as sulfite lignin or sulfonated lignin, or alternately sulfonated lignite, sulfonated tannins, napthalene sulfonates or other related compounds as the UV protectant.
