Massachusetts Pesticide License Practice Exam

Which of the following reduces the likelihood of drift during pesticide application?

1. Using lower volumes of pesticide

2. Employing high-pressure nozzle settings

3. Incorporating drift control additives

4. Increasing travel speed while spraying

The correct answer is: Incorporating drift control additives

Incorporating drift control additives is an effective method to reduce the likelihood of drift during pesticide application. Drift can occur when spray particles become airborne and move away from the intended application area, potentially harming non-target organisms and the environment. Drift control additives work by increasing the droplet size of the spray, which helps to minimize the dispersion of droplets in the air. By promoting the formation of larger droplets, these additives ensure that the pesticide remains focused on the target area, reducing off-target movement due to wind or other factors. This approach is particularly important for ensuring effective pest control while maintaining compliance with environmental regulations and protecting beneficial organisms. Drift control additives are a recognized and responsible practice in pesticide application, addressing both efficacy and safety concerns.
