Methods of using aqueous pesticide concentrates containing a pesticide (such as an auxinic herbicide), a surfactant, and a petroleum derived paraffinic oil and the use of such aqueous pesticide spray mixtures incorporating such concentrates are described. The aqueous pesticide concentrates include from 5 to 90 weight percent of a pesticide, from 0.1 to 20 weight percent of a surfactant, and from 0.1 to 20 weight percent of a petroleum derived paraffinic oil. The aqueous pesticide concentrates contain a pesticide, such as a water soluble salt of a herbicide, and form a homogeneous liquid that forms a stable emulsion upon dilution into a spray solution.
