What is a "pesticide drift"?

The definition of "pesticide drift" specifically refers to the movement of pesticide particles through the air to unintended areas outside the target application zone. This phenomenon occurs when the application of pesticides does not stay within the limits of the intended area, resulting in the unintentional exposure of non-target surfaces or organisms.

Pesticide drift can happen due to various factors, such as wind conditions, temperature, and the method of application used. Understanding this concept is crucial for pesticide applicators to minimize environmental impact and avoid harming non-target species, including beneficial insects, aquatic life, or nearby crops.

Other options describe related but distinct phenomena. For instance, the accumulation of pesticide in water sources pertains to runoff or leaching, while the formation of pesticide clouds involves the presence of pesticide vapors in the air during application. Residue left on plants after application refers to the remaining pesticide on the surfaces of treated plants, which doesn't convey the same concept of unintentional movement through the air.
