Which of the following are the two types of pesticide drift?

The two types of pesticide drift are indeed vapor drift and spray or dust particle drift. Vapor drift refers to the movement of pesticide vapors into the air once the pesticide has been applied. This can occur when the pesticide evaporates, allowing it to be carried by air currents, potentially affecting areas far from the application site.

On the other hand, spray or dust particle drift involves the physical movement of pesticide droplets or solid particles that are dispersed during application. This can happen due to wind or other environmental factors, leading to unintended deposition on non-target areas.

Understanding these two types of drift is crucial for pest control operators to minimize off-target effects, adhere to regulations, and protect beneficial organisms, human health, and the environment.
