Abstract:
Pesticidal compositions useful in agriculture but subject to rapid degradation on exposure to sunlight are stabilized by including in the formulation an amount of a sulfonated copolymer of catechin and leucocyanidin having a molecular weight in the range of about 3000 to 6000, or of an agronomically acceptable metal or ammonium salt thereof, in an amount sufficient to provide a concentration of about 1/4 lb. to 5 lbs. per acre.
