True or False: Drift is most likely to occur on windy days.

Drift refers to the unintentional movement of pesticide spray from the target area to non-target areas during application. Wind is a significant factor that contributes to pesticide drift because it can carry airborne particles, droplets, or vapor away from the application site. On windy days, the increased air movement can disperse these particles over larger distances, reducing their effectiveness and posing risks to nearby plants, animals, and even human health.

When conditions are windy, the chances of drift occurring increase substantially, making it crucial for applicators to assess weather conditions before spraying pesticides. This understanding is vital for effective pest control while minimizing unintended consequences. Therefore, stating that drift is most likely to occur on windy days is indeed true.
