Which of the following is NOT a common method of preventing pesticide drift?

Preventing pesticide drift is crucial for ensuring that chemicals reach their intended targets without affecting non-target areas, including adjacent crops, wildlife, and human populations. Using high-pressure spray equipment is not a common method for preventing drift, and in fact, it can contribute to drift rather than mitigate it.

High-pressure spraying tends to create smaller droplets. These smaller droplets are more susceptible to wind, increasing the chances of them being carried away from the target area. In contrast, using low-pressure spray equipment creates larger drops that are less likely to drift. Spraying during calm weather minimizes the potential movement of pesticide particles through the air, and adjusting nozzle types based on wind speed helps to optimize droplet size for the existing conditions, both of which are effective methods in controlling drift. Thus, high-pressure spraying is counterproductive in the context of drift prevention.
