Abstract
Abstract A method for reducing pesticide drift caused by crystallization of a pesticide from a pesticide spraying formulation. Crystallization of a pesticide from a pesticide spraying formulation is suppressed by incorporating an expoxidized vegetable oil into the formulation. The method increases pesticidal efficacy of a pesticide applied in the form of a pesticide spraying formulation. A pesticide spraying formulation is provided which comprises a pesticide, a diluent and an epoxidized vegetable oil.
