1. An aqueous composition comprising from 0.005 to 0.45 wt %, based on the total weight of the composition, of at least one hydrophobically modified cationic polymer obtainable by performing a polymerization of the monomers:
- (i) 5 to 80 weight percent of an alkyl ester of acrylic acid or an alkyl ester of methacrylic acid, wherein the alkyl group has 1 to 4 carbon atoms; and
(ii) 5 to 80 weight percent of a monomer selected from the group consisting of a mono- or di-alkylamino alkyl(meth)acrylate, and a mono or di-alkylamino alkyl(meth)acrylamide, wherein the alkyl group has 1 to 4 carbon atoms, and mixtures thereof; and
(iii) 0.1 to 30 weight percent of an associative monomer selected from the group consisting of;
(a) an ethylenically unsaturated copolymerizable surfactant monomer, obtained by condensing a nonionic surfactant, having a C5-C32 hydrocarbyl group, with an ethylenically unsaturated carboxylic acid or the anhydride thereof; and
(b) a hydrocarbyl ester of acrylic acid or a hydrocarbyl ester of methacrylic acid, wherein the hydrocarbyl group has from 5 to 32 carbon atoms; and
(iv) 0 to 1 weight percent of a cross-linking monomer;
wherein the weight percentages of the monomers are being based on the total weight of all monomers present in the polymerization reaction; and
one or more pesticides and/or crop production chemicals.

Abstract
The present invention relates to the use of certain hydrophobically modified cationic polymers, prepared by polymerising an alkyl ester of acrylic acid or an alkyl ester of methacrylic acid, a nitrogen containing monomer; and an associative monomer; as deposition enhancers for pesticides and crop production chemicals, such as plant growth regulators, fertilizers and micronutrients, in aqueous solutions; an aqueous composition comprising these polymers and one or more pesticides and/or crop production chemicals, a process for preparing said aqueous composition, and the use of said composition for treatment of plants.
