1. A dispersion of a pesticide in an agricultural oil comprising: (a) an oil-compatible, polyurea-based polymeric rheology modifier, (b) an agricultural oil, and (c) a dispersed particulate pesticide, wherein the oil-soluble, polyurea-based polymeric rheology modifier has the following structure:

OG Complex Work Unit Chemistry
where y is from 1 to 30, and R is a polyether polyurethane prepolymer of the structure:

OG Complex Work Unit Chemistry
where each x independently is from 1 to 200, wherein the polymeric rheology modifier has a number average molecular weight (Mn) of from 1000 daltons to 100,000 daltons, and wherein the dispersion comprises from 0.1 to 20% (a), from 10 to 99.8% wt. % (b) from 0.1 to 70 wt. % (c), wherein a total wt. % of (a), (b), (c), is 100 wt. %.
