What should be used to protect sensitive areas from pesticide drift?

Using buffer zones is an effective strategy for protecting sensitive areas from pesticide drift. Buffer zones are designated areas surrounding the application site where no pesticides are applied. These zones serve as a barrier that absorbs or reduces the potential for pesticide particles to drift into nearby sensitive areas such as water bodies, habitats for wildlife, or residential areas. By implementing buffer zones, applicators can significantly minimize environmental impacts and ensure compliance with regulatory guidelines regarding pesticide use.

The other options would not effectively mitigate drift. More frequent spraying could increase the likelihood of drift incidents rather than reduce them. Higher pesticide concentrations could enhance the risks associated with drift, potentially leading to greater contamination of sensitive areas. Likewise, increased spray pressures might cause droplets to be smaller, enabling them to drift further away from the intended application site, thus worsening the drift issue. Using buffer zones is a scientifically recognized practice aimed at protecting the environment while allowing for necessary pesticide application.
