Which factor does NOT affect particle drift?

The factor that does not affect particle drift is the type of pesticide used. Drift primarily refers to the movement of pesticide particles away from the intended application area, which is influenced by physical factors rather than the chemical properties of the pesticide itself.

Wind is a significant contributor to drift, as strong gusts can carry particles far from where they were applied. Temperature can play a role as well, since it affects evaporation rates and the behavior of spray particles. The height of the release also impacts drift; particles released from a higher elevation can be carried further by wind currents compared to those released closer to the ground.

While different types of pesticides may have varying properties, such as viscosity or size, it is their physical characteristics like droplet size and application method that can interact with wind and environmental conditions. However, the fundamental aspect of particle drift itself is not dependent on the specific type of pesticide being used, making it the correct answer to the question regarding which factor does not affect particle drift.
