Correct answer: A. Gallons per acre

Gallons per acre is the standard unit used to express and verify broadcast liquid pesticide application rates, which is the goal of calibration.

• B: Ground speed (miles per hour) is one input variable used in calibration calculations, but calibration's output measurement is expressed as an application rate like gallons per acre, not speed alone.
• C: Nozzle pressure (psi) affects droplet size and output but, by itself, is not the unit used to express the final calibrated application rate.
• D: Kilowatt-hours measure electrical energy consumption and have no relevance to pesticide application rate calibration.

Correct answer: B. The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)

FIFRA (7 U.S.C. § 136 et seq.) is the core federal statute governing pesticide registration, labeling, distribution, sale, and use, and it is the basis for applicator certification programs.

• A: The Clean Water Act regulates discharges to waters of the United States and is a separate statute from pesticide registration and use.
• C: RCRA governs hazardous waste management, a separate regulatory program from pesticide product registration and use.
• D: TSCA governs most industrial chemicals but specifically excludes pesticides, which are instead regulated under FIFRA.

Correct answer: B. Registered with EPA

FIFRA § 3 (7 U.S.C. § 136a) requires EPA to register a pesticide product, based on data demonstrating it will not cause unreasonable adverse effects, before it may be sold or distributed.

• A: The FDA plays a role in setting pesticide tolerances on food in coordination with EPA, but product registration itself is an EPA function under FIFRA.
• C: States can impose additional registration requirements, but this does not replace the federal EPA registration requirement under FIFRA.
• D: Registration requires EPA review of manufacturer-submitted data, not an unreviewed private certification chosen solely by the manufacturer.

Correct answer: B. Using a registered pesticide in a manner inconsistent with its labeling is a federal violation

Under FIFRA § 12(a)(2)(G) (7 U.S.C. § 136j), it is unlawful to use a registered pesticide in a manner inconsistent with its labeling, which is why the phrase 'the label is the law' is used in applicator training.

• A: Label directions are not merely suggestions; they carry the force of law once a product is registered and labeled by EPA.
• C: The entire label, including precautionary statements, use directions, rates, and restrictions, carries legal weight, not just the brand name.
• D: Certification does not exempt an applicator from following label directions; certified applicators remain bound by the label just like anyone else.

Correct answer: B. The EPA registration number and signal word

40 CFR 156.10 requires labeling elements including the product name, EPA registration number, ingredient statement, signal word, precautionary statements, and directions for use.

• A: An individual applicator's personal contact information is not a required labeling element under 40 CFR 156.10.
• C: Retail pricing is a commercial matter and is not a required EPA labeling element.
• D: A company's stock ticker symbol has no bearing on pesticide product labeling requirements.
