1. Which federal agency is primarily responsible for registering pesticides in
the United States?
A. FDA (Food and Drug Administration)
B. USDA (United States Department of Agriculture)
C. OSHA (Occupational Safety and Health Administration)
D. CDC (Centers for Disease Control and Prevention)
E. EPA (Environmental Protection Agency)
Correct Answer: E. EPA (Environmental Protection Agency)
EXPERT RATIONALE: The EPA is the federal agency that registers pesticides
under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), ensuring
pesticides meet safety and efficacy standards before they can be sold or used in the
U.S.
,2. In Virginia, which agency enforces the Virginia Pesticide Control Act?
A. Virginia Department of Health
B. Virginia Department of Environmental Quality
C. Virginia Department of Agriculture and Consumer Services (VDACS)
D. Virginia Department of Wildlife Resources
E. Virginia Department of Labor and Industry
Correct Answer: C. Virginia Department of Agriculture and Consumer
Services (VDACS)
EXPERT RATIONALE: VDACS is the state agency responsible for enforcing
pesticide regulations in Virginia, including licensing, inspections, and enforcement
actions under the Virginia Pesticide Control Act.
3. The signal word "DANGER" on a pesticide label indicates:
A. The pesticide is slightly toxic
B. The pesticide is moderately toxic
C. The pesticide is highly toxic or severely irritating
D. The pesticide is non-toxic
E. The pesticide is restricted use only
Correct Answer: C. The pesticide is highly toxic or severely irritating
EXPERT RATIONALE: "DANGER" (often accompanied by "POISON") is the signal
word for Toxicity Category I pesticides, the most toxic category. These products can
cause death or severe injury with very small amounts of exposure.
4. What does the term "restricted-use pesticide" (RUP) mean?
, A. The pesticide can only be used indoors
B. The pesticide is banned in Virginia
C. The pesticide can only be purchased and applied by certified applicators
D. The pesticide requires a doctor's prescription
E. The pesticide can only be used during certain seasons
Correct Answer: C. The pesticide can only be purchased and applied by
certified applicators
EXPERT RATIONALE: Restricted-use pesticides (RUPs) pose greater risks to
humans or the environment and can only legally be purchased and used by
certified pesticide applicators or persons under their direct supervision.
5. Which part of the pesticide label is a legally binding document?
A. The advertising on the container
B. The entire label
C. Only the directions for use
D. Only the first aid section

EXPERT RATIONALE: The pesticide label is a legal document. FIFRA requires that
applicators follow all label directions. Violating label instructions is a violation of
federal law — "The label is the law."
6. The LD50 value of a pesticide refers to:
A. The amount of pesticide needed to kill all exposed organisms
B. The lethal dose that kills 50% of a test population
, C. The concentration of pesticide in water that is lethal
D. The time it takes for 50% of the pesticide to break down
E. The temperature at which 50% of the pesticide evaporates
Correct Answer: B. The lethal dose that kills 50% of a test population
EXPERT RATIONALE: LD50 (Lethal Dose 50) is a standard measure of acute
toxicity. It represents the dose required to kill half of a test animal population.
Lower LD50 values indicate greater toxicity.
7. Which signal word indicates the LOWEST level of toxicity on a pesticide
label?
A. DANGER
B. WARNING
C. CAUTION
D. NOTICE
E. ALERT
Correct Answer: C. CAUTION
EXPERT RATIONALE: Signal words in order of decreasing toxicity are: DANGER
(most toxic) > WARNING (moderately toxic) > CAUTION (least toxic). "CAUTION"
indicates Toxicity Category III or IV pesticides.
8. Which route of pesticide exposure is generally the most common for
applicators?
A. Inhalation
B. Oral ingestion
C. Dermal (skin) contact
D. Ocular (eye) contact
