What this exam covers
5 real sample questions
Which factor most directly increases the risk of spray drift during pesticide application?
A. Using larger droplet sizes and low wind speeds
B. Using very fine droplet sizes combined with high wind speeds
C. Applying early in the morning with no wind
D. Using label-specified nozzle pressure
Show answer and reasoning

Correct answer: B. Using very fine droplet sizes combined with high wind speeds

Correct. Fine droplets are more easily carried by air currents, and higher wind speeds increase the distance and area over which drift can travel, both increasing drift risk.

  • A: Larger droplets and calm conditions reduce drift risk, the opposite of the described factor.
  • C: Calm early morning conditions typically reduce drift risk compared to windy periods.
  • D: Following label-specified pressure settings, rather than exceeding them, is a drift-reduction practice.

What is a common minimum passing score benchmark used by many state pesticide applicator certification exam programs?
A. Around 70%, though the exact passing score is set by the specific state program
B. 0%, since any attempt passes
C. 100%, with no margin for error allowed
D. There is no passing score; everyone who takes the exam is certified
Show answer and reasoning

Correct answer: A. Around 70%, though the exact passing score is set by the specific state program

Correct. While the exact threshold is set by each state program, a commonly used passing score benchmark for pesticide applicator exams is around 70%.

  • B: There is a defined passing threshold; not every attempt automatically passes.
  • C: A 100% requirement with zero margin is not the typical standard used by state programs.
  • D: Certification is contingent on meeting a passing score, not automatically granted to all test-takers.

Under FIFRA, who has primary authority to certify pesticide applicators within a state, provided the state's plan is EPA-approved?
A. Only the EPA Administrator directly, with no state role
B. The state's lead pesticide regulatory agency, operating under an EPA-approved certification plan
C. The applicator's employer
D. The pesticide manufacturer
Show answer and reasoning

Correct answer: B. The state's lead pesticide regulatory agency, operating under an EPA-approved certification plan

Correct. FIFRA Section 4 and 40 CFR Part 171 allow states to certify applicators under their own EPA-approved certification plans, which is how most state agencies administer applicator certification.

  • A: FIFRA specifically allows states to administer their own certification programs once EPA approves the state's plan.
  • C: An employer has no independent regulatory certification authority under FIFRA.
  • D: A pesticide manufacturer has no certification authority under FIFRA.
Source: FIFRA § 4; 40 CFR Part 171
Under FIFRA, a 'certified applicator' is defined as:
A. Anyone who has purchased a pesticide
B. Any individual who is certified as authorized to use or supervise the use of any restricted-use pesticide
C. Only a licensed pest control business owner
D. Only someone with a college degree in agriculture
Show answer and reasoning

Correct answer: B. Any individual who is certified as authorized to use or supervise the use of any restricted-use pesticide

Correct. FIFRA Section 2(e) defines a certified applicator as an individual certified as authorized to use or supervise the use of restricted-use pesticides.

  • A: Simply purchasing a pesticide does not confer certified applicator status.
  • C: Certification is an individual credential, not necessarily tied to business ownership.
  • D: A college degree is not the legal basis for certified applicator status under FIFRA.
Source: FIFRA § 2(e)
Under FIFRA, it is generally unlawful for any person to use a registered pesticide in a manner that is:
A. Consistent with its labeling
B. Inconsistent with its labeling
C. Consistent with integrated pest management principles
D. Reviewed annually by the user
Show answer and reasoning

Correct answer: B. Inconsistent with its labeling

Correct. FIFRA Section 12(a)(2)(F) makes it unlawful to use a registered pesticide in a manner inconsistent with its labeling.

  • A: Using a pesticide consistent with its labeling is the lawful, required approach.
  • C: IPM consistency is a best practice, not the specific statutory prohibition described.
  • D: Annual review by the user is not a FIFRA requirement described here.
