Which of the following methods can minimize pesticide drift?

• A. Spray at high pressure
• B. Use the smallest practical nozzle openings
• C. Spray when winds are calm
• D. Apply pesticides during midday

Answer: (C)

Minimizing pesticide drift is crucial in ensuring that pesticides affect only the intended target areas and do not harm neighboring plants, wildlife, or human populations. Spraying when winds are calm is an effective method for reducing drift because high winds can carry pesticide droplets away from the application site, increasing the risk of unintended exposure. When conditions are calm, the application is more likely to stay within the intended area, thereby enhancing efficacy and safety. Other methods, such as spraying at high pressure or using smaller nozzle openings, can inadvertently increase drift because they may create finer droplets that are more susceptible to being carried by wind currents. Applying pesticides during midday can also be problematic, as higher temperatures and wind activity are often prevalent during this time, which can lead to increased drift potential. Therefore, choosing to spray when winds are calm is the best practice for minimizing pesticide drift.
