Wyoming Pesticide Applicator Practice Test 2025 – Complete Exam Prep

Question: 1 / 605

How can spray drift be avoided?

Using temperature inversion

Close all building windows near the application site

Apply products on hot days

Choose low-volatility products

Applying products on hot days can increase the risk of spray drift as heat and wind can cause the droplets to evaporate and spread further. Using temperature inversion may seem like a good idea as it creates a layer of calm air, but it can also trap pesticides near the ground and increase the risk of drift. Closing windows near the application site can also help, but it is not a foolproof method as drift can still occur through other openings or ventilation systems. Choosing low-volatility products is the best way to avoid spray drift as they have less tendency to form droplets that can easily drift away.
