Colorado Pest Control State Practice Test

Drift happens when spray droplets are carried away from the target by air currents. To keep the pesticide where you want it, you control how the spray leaves the nozzle. Using drift-reducing practices, like selecting the right nozzle that produces appropriate droplet sizes and keeping the nozzle closer to the target by lowering the spray height, makes droplets larger and less easily blown off course. This combination directly reduces the amount of off-target deposition and increases the chance the product lands where intended. Applying in high wind or ignoring weather conditions are situations that raise drift risk, and there isn’t a practical “non-drift spray” option. So focusing on proper nozzle choice and maintaining a low, targeted application height is the most effective way to minimize drift.
