An adjuvant composition for modifying the spray properties of an aqueous pesticide composition contains at least one fatty alcohol having a solubility in water of less than 10 percent by weight, in an amount that is effective, when the adjuvant composition is diluted in the aqueous pesticide composition and the aqueous pesticide composition is spray applied, as a drift control agent for the spray applied aqueous pesticide composition and at least one of a liquid medium, one or more hydrotropes, or one or more surfactants, a concentrated pesticide composition contains a liquid medium, one or more pesticide compounds, and at least one such fatty alcohol, in an amount that is effective, when the concentrated pesticide composition is diluted to form an aqueous pesticide composition and the aqueous pesticide composition is spray applied, as a drift control agent for the spray applied aqueous pesticide composition an end use pesticide composition contains water, a pesticide, and at least one such fatty alcohol in an amount that is effective, when the aqueous pesticide composition is spray applied, as a drift control agent for the spray applied aqueous pesticide composition, and a method for controlling spray drift of an aqueous pesticide composition includes the steps of incorporating in the aqueous spray composition an amount effective of at least one such fatty alcohol that is effective, when the aqueous pesticide composition is spray applied, as a drift control agent for the spray applied aqueous pesticide composition, and spray applying the pesticide composition to a target pest and/or to the environment of the target pest.
