What is adulteration in pesticide regulation?

• A. Labeling a pesticide incorrectly
• B. Contaminating a pesticide with another substance or compromising its quality, making it unsafe or ineffective
• C. Over-application of the pesticide
• D. Using the wrong container for storage

Answer: (B)

Adulteration in pesticide regulation means contaminating a product or otherwise compromising its quality in a way that makes it unsafe or ineffective. Regulators require pesticides to meet defined purity, potency, and stability standards, so any addition of an unauthorized substance or degradation of the product’s ingredients undermines safety and performance. Examples include introducing other chemicals, diluting a concentrated formulation beyond approved specifications, or lapses in manufacturing that alter the product’s composition.

Labeling inaccuracies affect the information on the package rather than the product’s chemical integrity, so they aren’t considered adulteration. Over-application relates to how a product is used, which can cause misuse or safety risks but doesn’t inherently change the product’s composition. Using the wrong container is a packaging/handling issue and not a direct adulteration of the product itself.
