Pesticide spray drift refers to the movement of pesticide droplets away from the target area during application, leading to unintentional exposure of non-target organisms, such as plants, animals, and humans. This phenomenon can result in environmental damage, decreased efficacy of the pesticide, and potential health risks. Researchers in this area study factors that influence spray drift, such as weather conditions, application methods, and formulation of pesticides, in order to develop strategies to minimize drift and mitigate its negative impacts. Strategies may include using drift-reducing technologies, adjusting application timing, or implementing buffer zones to protect adjacent areas.
