Georgia Pest Control Practice Test

Which statement is not true about particle drift?

1. Invisible particles suspended in the air

2. The distance of drift may be affected by wind, temperature, and height of pesticide release

3. Smaller particles will drift farther than larger particles

4. May damage non-target organisms

The correct answer is: Invisible particles suspended in the air

The statement that invisible particles suspended in the air is not true about particle drift is accurate because particle drift refers specifically to larger pesticide particles that can become airborne during application. This phenomenon is primarily caused by environmental factors that influence the movement and dispersal of these particles once they are released. While it is true that very fine particulate matter can be suspended in the air, the term "particle drift" in the context of pest control more commonly describes the behavior of pesticide droplets or particles that have a tangible mass and can be carried by wind, temperature fluctuations, and the dynamics of the pesticide application itself. This understanding of particle drift is essential for pest control operators to minimize unintended exposure and potential damage to non-target organisms, which is addressed in the other statements. Recognizing that drift does not typically involve entirely invisible particles helps clarify the importance of using appropriate application techniques to prevent environmental contamination and protect beneficial organisms.
