ABSTRACT:
A method for microencapsulating agriculturally active substances such as pesticides to provide improved resistance to environmental degradation, especially ultra-violet light. The method employs as the UV protectant lignosulfonates, such as sulfite lignin or sulfonated lignin, or alternately sulfonated lignite, sulfonated tannins, napthalene sulfonates or other related compounds in combination with a protein such as a high bloom gelatin to form a capsule wall. The capsule wall formed by the interaction of these components is durable and has an ultra-violet protectant as an integral part of its structure.
