What this exam covers
5 real sample questions
A pesticide with the signal word WARNING on its label falls into which EPA toxicity category under 40 CFR 156.64?
A. Category I
B. Category II
C. Category III
D. Category IV
Show answer and reasoning

Correct answer: B. Category II

  • A: Category I requires the signal word DANGER, not WARNING.
  • C: Category III requires the signal word CAUTION.
  • D: Category IV products meeting all-route criteria are not required to carry a signal word at all, and if one is used it must be CAUTION.
Source: 40 CFR 156.64
Under 40 CFR 156.64, a Toxicity Category IV pesticide that meets the least-toxic criteria for all exposure routes:
A. Must display DANGER
B. Must display WARNING
C. Is not required to bear a signal word, but if one is used it must be CAUTION
D. Must display both CAUTION and WARNING together
Show answer and reasoning

Correct answer: C. Is not required to bear a signal word, but if one is used it must be CAUTION

  • A: DANGER is reserved for Category I, the most acutely toxic tier.
  • B: WARNING is reserved for Category II.
  • D: 156.64 does not allow stacking two signal words on one label; only a single word applies.
Source: 40 CFR 156.64
Under 40 CFR 156.10, which two identification numbers must appear on every registered pesticide label?
A. The state license number and the applicator ID number
B. The EPA Registration Number and the EPA Establishment Number
C. The DOT hazard class number and the UN shipping number
D. The SDS number and the CAS number
Show answer and reasoning

Correct answer: B. The EPA Registration Number and the EPA Establishment Number

  • A: State license and applicator ID numbers are not label elements required by 156.10 — they belong to the individual applicator, not the product.
  • C: DOT/UN shipping numbers govern transport documentation, not the FIFRA product label under 156.10.
  • D: The CAS number identifies a chemical compound generically; 156.10 requires the EPA Reg. No. and Est. No., not CAS or SDS numbers.
Source: 40 CFR 156.10
The ingredient statement required by 40 CFR 156.10 must express active and inert ingredients as:
A. Percentage by weight of the total formulation
B. Milligrams per liter of finished spray solution
C. Parts per million at the labeled application rate
D. A simple list of chemical names with no percentages
Show answer and reasoning

Correct answer: A. Percentage by weight of the total formulation

  • B: The label ingredient statement is a formulation disclosure (percent by weight), not a use-rate calculation like mg/L of spray solution.
  • C: PPM at the application rate is a mixing calculation the applicator performs; it is not how 156.10 requires ingredients to be declared on the label itself.
  • D: A name-only list without percentages would fail 156.10, which specifically requires active and inert ingredients to be identified by percentage weight.
Source: 40 CFR 156.10
The statement "It is a violation of Federal law to use this product in a manner inconsistent with its labeling" is required by 40 CFR 156.10 to appear:
A. Only on Restricted Use Pesticide labels
B. In the Directions for Use section of every pesticide label
C. Only on labels for products with an oral LD50 under 50 mg/kg
D. On the shipping carton but not the container label
Show answer and reasoning

Correct answer: B. In the Directions for Use section of every pesticide label

  • A: The misuse statement is a general labeling requirement under 156.10, not limited to Restricted Use products.
  • C: Toxicity category has no bearing on whether the misuse statement is required — 156.10 requires it on every registered label regardless of Category I-IV status.
  • D: The requirement attaches to the product labeling itself, not just outer shipping packaging.
