ABSTRACT:
Flowable aqueous pesticidal concentrates comprising water, 10 to 80% by weight, based on the water, of a water-insoluble solid particulate pesticide and a vinyl alcohol/vinyl acetate polymer having about 5 to 15 mols of vinyl acetate per 100 mols of copolymer and a molecular weight of at least 50,000, wherein the weight ratio of pesticide to copolymer is in the range of 1:1 and 1000:1. These concentrates are compatible with other agricultural chemicals systems. This application is a continuation of application Ser. No. 206,516, filed Dec. 9, 1971 now abandoned, which in turn is a continuation of application Ser. No. 829,769, filed June 2, 1969, now abandoned.
