Pest Control Aircraft Pilot Practice Test

What can inadequate agitation in a tank lead to?

1. Overspray

2. Pesticide settling

3. Increased vapor pressure

4. Improper nozzle function

The correct answer is: Pesticide settling

Inadequate agitation in a tank can lead to pesticide settling. This occurs because many pesticide formulations are designed to stay mixed as long as they are continually agitated. When agitation is insufficient, solid particles or active ingredients may not remain suspended and can settle at the bottom of the tank. This settling can result in an uneven application of the pesticide, as the mixture may not contain a uniform distribution of the active ingredient throughout the spray solution. Ensuring proper agitation is critical for effective pest control, as it guarantees that the pesticide is adequately mixed and ready to be applied evenly across the target area. If the active ingredients are allowed to settle, the spray may be ineffective and result in inadequate pest control. Therefore, proper agitation is crucial in maintaining the efficacy of the pesticide during application.
