Disclosed is an aqueous composition comprising 0.005 to 0.5 wt% of a hydrophobically modified cationic polymer, prepared by polymerising an alkyl ester of acrylic acid or an alkyl ester of methacrylic acid, a nitrogen containing monomer; and an associative monomer. The composition is suitable as deposition enhancers for pesticides and crop production chemicals, such as plant growth regulators, fertilizers and micronutrients, in aqueous solutions. In a particular embodiment, the alkyl ester of acrylic acid is ethyl acrylate and the nitrogen monomer is N,N-dimethylamino ethyl methacrylate (DMAEMA). |
