Comparative study of properties of different pesticide formulations of the same active ingredient

Characteristics of two formulations of trifluralin, an emulsifiable concentrate (EC) and emulsion, oil in water (EW), the latter being a new formulation of our design, were investigated and compared. Attention was focused on particle size distribution and aspects of the two aqueous dilute formulations as the most characteristic and comparable parameters. The results show that the trifluralin EW formulation has certain advantages over the EC formulation, but a final estimate will be possible only after testing biological efficacy of the new formulation (EW).
