Structural Pest Control Applicator Practice Exam

Which of the following statements about pesticide residue is NOT true?

1. Some residues may stay for months or years.

2. Residue info is necessary for each crop treated.

3. Residues are only found on target crops and surfaces.

4. Residues can accumulate in the environment.

The correct answer is: Residues are only found on target crops and surfaces.

The statement regarding pesticide residues that is not accurate is that residues are only found on target crops and surfaces. This assertion underestimates the potential for pesticide residues to disperse beyond intended areas of application. In reality, pesticide residues can migrate from the target locations through various means, including wind, water runoff, and social activities like harvesting. Consequently, residues can also be detected in surrounding environments, including non-target plants and nearby ecosystems. The other statements about pesticide residues are indeed true. Some residues can persist in the environment for extended periods, sometimes lasting for months or even years, which is critical for understanding the long-term effects of pesticide use. Having residue information available for each crop treated is essential for ensuring safe food production and adherence to regulatory standards. Moreover, pesticide residues can accumulate in the environment due to repeated applications, which highlights the necessity for monitoring and managing pesticide use to prevent environmental harm.
