Which of the following pesticide formulations is less likely to drift during windy conditions?

Granular pesticide formulations are less likely to drift during windy conditions due to their physical form. Granules are solid particles that fall quickly to the ground after application because of their weight and the absence of a carrier that allows them to remain airborne. This characteristic minimizes the potential for drift, making granular pesticides a suitable choice for applications in windy environments.

In contrast, aqueous solution pesticides, emulsifiable concentrates, and wettable powders can all create fine droplets when applied, especially using spray equipment. These fine droplets are more susceptible to being carried away by the wind, increasing the risk of drift and potential off-target application. The size and nature of the particles in these formulations enable them to remain suspended in the air longer, which is why they are more prone to drift compared to granular formulations.
