What is the validity of the statement: Because of low amounts of material, ultra-low volume (ULV) sprayers have no problems with drift?

The statement is false because ultra-low volume (ULV) sprayers, despite using low amounts of pesticide material, can still pose a significant risk of drift. Drift occurs when fine droplets of pesticide are carried away from the intended target area by wind or other environmental factors, and ULV sprayers produce very small droplets that are particularly susceptible to this movement.

The use of undersized droplets means that while the volume applied per area is low, the chance for those droplets to be affected by air currents increases. Consequently, conditions such as wind speed, temperature, and humidity can all contribute to the potential for drift, making it important for applicators to consider these factors when using ULV technology. Proper techniques and precautions are essential to minimize this risk, regardless of how low the application volume is.
