Abstract: An aqueous agricultural composition includes a pesticide, water, and a co-polymer. The co-polymer is the reaction product of an acrylamide monomer and a macromonomer. The acrylamide monomer and the macromonomer react together in the absence of an anionic monoethylenically unsaturated monomer including an acidic group chosen from —COOH, —SO3H, —PO3H2 and associated salts. The disclosed aqueous agricultural composition may be incorporated into agricultural spray operations and demonstrates effective reduction of driftable droplets.
