Correct answer: A. May generally cause unreasonable adverse effects on the environment or injury to applicators without additional restrictions on its use

Correct. Under FIFRA Section 3(d), EPA classifies a pesticide as restricted use if, without added use restrictions, it may generally cause unreasonable adverse effects on the environment, including injury to the applicator.

• B: RUP classification is based on risk of adverse effects, not on a product being non-toxic; RUPs are, by definition, products of concern requiring added restriction.
• C: Price is not a factor in FIFRA's restricted use classification; classification is a risk-based determination.
• D: Restricted use classification is unrelated to package/container size or bulk sale status.

Correct answer: A. Use or supervise the use of a restricted use pesticide (RUP)

Correct. 40 CFR Part 171 implements FIFRA's certification requirement that restricted use pesticides be applied only by, or under the direct supervision of, a certified applicator.

• B: General-use pesticides are not restricted to certified applicators for purchase; certification requirements attach specifically to restricted use pesticides.
• C: Reading a label requires no certification; anyone handling a pesticide is expected to read the label regardless of certification status.
• D: Simply storing an unopened container does not require applicator certification; certification governs use/application and supervision.

Correct answer: A. A core (general standards) exam plus at least one category-specific exam for each pest control category in which they intend to apply RUPs

Correct. Commercial applicator certification under Part 171 requires passing a core exam on general competency plus a separate exam for each specific pest control category the applicator intends to work in.

• B: There is no single combined exam substituting for both the core and category-specific requirements under the federal certification standard.
• C: Written examination demonstrating practical knowledge is required; an affidavit alone does not satisfy the certification standard.
• D: Both the core exam and applicable category exam(s) are required; the core exam is not optional for commercial applicators.

Correct answer: A. On property owned or rented by the applicator or their employer, without compensation for the application itself

Correct. A private applicator uses or supervises RUP use to produce an agricultural commodity on land owned or rented by themselves or their employer, and does not apply pesticides for hire.

• B: Applying pesticides for hire on other people's property is the defining characteristic of a commercial applicator, not a private applicator.
• C: Private applicator status is not limited to greenhouse settings open to the public; it centers on producing an agricultural commodity on owned/rented land.
• D: Aerial application is a specific method/category, not the defining feature that separates private from commercial applicator status.

Correct answer: A. It is a legal document, and using a pesticide in a manner inconsistent with its labeling is a violation of federal law

Correct. FIFRA makes it unlawful to use a registered pesticide in a manner inconsistent with its labeling; the label functions as a legally enforceable document.

• B: The label is far more than marketing material; it carries the force of federal law under FIFRA Section 12(a)(2)(G).
• C: The 'label is the law' principle applies to all applicators, private and commercial alike, not just commercial applicators.
• D: Purchasing the product does not exempt the user from following label directions; label compliance is an ongoing legal obligation each time the product is used.
