Pest Control Aircraft Pilot Practice Test

What is a major disadvantage of cone pattern nozzles in spray applications?

1. Tend to produce large droplet sizes

2. Are often difficult to maintain

3. Tend to produce small droplet sizes prone to drift

4. Require higher pressure to operate

The correct answer is: Tend to produce small droplet sizes prone to drift

The correct answer highlights that cone pattern nozzles tend to produce small droplet sizes, which can be prone to drift. This is significant in pest control applications because smaller droplets are more susceptible to being carried away by wind and air currents, potentially leading to off-target application. This can result not only in ineffective pest control but also in unintended exposure to non-target organisms or areas. Understanding the implications of droplet size is crucial for effective pest management. Smaller droplets can provide better coverage and penetration in dense foliage but require careful consideration regarding environmental factors such as wind to minimize drift and maximize effectiveness.
