Georgia Pesticide Applicators Practice Exam

What term describes the property that prevents pesticide movement through a material during use?

1. Absorption

2. Biosafety

3. Persistence

4. Residue

The correct answer is: Residue

The term that accurately describes the property preventing pesticide movement through a material during use is 'residue.' This refers to the remnants of pesticides that remain on or in a material after application. Residue can affect how pesticides interact with surfaces or environments, playing a significant role in preventing further movement or degradation of the pesticide. Absorption, while relevant, refers to how a material takes in a substance, not necessarily preventing its movement. Biosafety pertains to the safe handling and use of biological and chemical agents, with considerations for human and environmental health, but does not directly address pesticide mobility. Persistence relates to how long a pesticide remains effective or is detectable in the environment but does not specifically involve the movement of the pesticide through materials during application. Thus, residue is the most fitting term for this concept.
