Which conditions are less likely to result in pesticide drift?

The conditions characterized by large spray droplets and low spray pressure are less likely to result in pesticide drift due to the physical properties influencing how pesticides are dispersed and carried through the air.

Large spray droplets tend to fall to the ground more quickly because of their weight, reducing the time they might be susceptible to being carried away by air movement. Low spray pressure results in a gentler application, which reduces the formation of fine droplets that are more easily affected by wind. Consequently, using larger droplets at lower pressure creates a more stable application method that minimizes the risk of drift, as less product is airborne compared to smaller, finer droplets that can remain suspended and be more readily affected by environmental factors.

In contrast, conditions such as fine droplets and high spray pressure lead to increased potential for drift. Fine droplets can be transported over longer distances by even light wind, while high spray pressure can create a mist of smaller droplets. Turbulent air can exacerbate drift by mixing these fine droplets into the air, allowing them to spread beyond the intended area. Heightened wind conditions are also a major factor in creating conditions favorable for drift, as wind can easily transport lighter droplets away from the target area. Thus, the combination of larger droplets and lower pressure is optimal for minimizing
