What is a potential impact of pesticide drift?

The correct answer highlights a significant concern in pesticide application practices: the potential for injury to non-target plants or animals. Pesticide drift refers to the movement of pesticide particles or droplets away from the intended application area, which can occur due to various factors such as wind, temperature, or improper application techniques. When pesticides drift, they can inadvertently affect surrounding ecosystems, harming beneficial organisms, ornamental plants, wildlife, and even livestock.

This unintended exposure can lead to several detrimental outcomes, including the reduction of biodiversity in the area, harm to pollinators, and damage to crops that are not meant to be treated with that particular pesticide. Additionally, the injury to non-target species can disrupt local food chains and ecological balance, which can have long-lasting effects on the environment.

In contrast, the other options provided do not accurately capture the concerns associated with pesticide drift. Increased pest resistance might occur due to over-reliance on specific pesticides, but it is not directly linked to the drift itself. Similarly, a reduction in applicator errors would not be related to the negative outcomes of drift; in fact, proper applicator training and practices are essential for minimizing drift. Lastly, increased effectiveness of the pesticide does not relate to the consequences of drifting; it highlights an
