Section 1: Core Exam Questions
Question 1
Which federal law establishes the requirements for pesticide registration,
labeling, and use in the United States?
A) Resource Conservation and Recovery Act (RCRA)
B) Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
C) Clean Water Act (CWA)
D) Occupational Safety and Health Act (OSHA)
Correct Answer: B
Rationale: FIFRA is the primary federal law regulating pesticides in the United
States. It governs pesticide registration, labeling requirements, distribution, sale,
and use. Pesticide labels have the force of law under FIFRA, and applicators must
follow them exactly.
Question 2
A pesticide applicator uses a product at a higher concentration than the label
allows because the pest population is severe. What violation has occurred?
A) Proper resistance management
B) Emergency exemption use
C) Illegal pesticide use
D) Integrated pest management
Correct Answer: C
,Rationale: The pesticide label is the law under FIFRA. Applying a pesticide at a
higher concentration, higher rate, or different method than specified is illegal
unless specifically authorized. Severe pest pressure does NOT allow an applicator
to exceed labeled directions.
Question 3
What is the most common route of pesticide exposure for applicators during
mixing, loading, and application?
A) Inhalation
B) Oral ingestion
C) Dermal (skin) contact
D) Ocular (eye) exposure
Correct Answer: C
Rationale: Dermal contact is the most common route of pesticide exposure.
Pesticides can be absorbed through the skin during mixing, loading, application,
cleanup, or from contaminated clothing. Wearing appropriate Personal Protective
Equipment (PPE) specified on the label is critical to prevent dermal exposure.
Question 4
Which signal word on a pesticide label indicates the highest level of acute
toxicity?
A) CAUTION
B) WARNING
C) DANGER
D) NOTICE
Correct Answer: C
Rationale: Signal words indicate relative acute toxicity to humans:
• DANGER or DANGER-POISON (with skull and crossbones) = highest toxicity
• WARNING = moderately toxic
, • CAUTION = slightly toxic or relatively nontoxic
Question 5
Which Wisconsin state agency regulates pesticide applicator certification and
licensing?
A) Wisconsin Department of Natural Resources (DNR)
B) Wisconsin DATCP (Department of Agriculture, Trade and Consumer Protection)
C) Wisconsin Department of Health Services
D) University of Wisconsin Extension
Correct Answer: B
Rationale: DATCP administers pesticide applicator certification, licensing, and
enforcement under Wisconsin Administrative Code ATCP 29. While DNR handles
some environmental permitting, DATCP is the primary regulatory agency for
pesticide applicators.
Question 6
The primary purpose of Integrated Pest Management (IPM) is to:
A) Eliminate all pest populations
B) Use a combination of methods to manage pests effectively and economically
C) Rely solely on chemical pesticides
D) Protect only the environment
Correct Answer: B
Rationale: IPM emphasizes combining biological, cultural, physical, and chemical
control methods to manage pests in a way that minimizes economic, health, and
environmental risks. The goal is not total elimination but managing pest
populations below damaging thresholds.
Question 7
, What is LD50 used to measure?
A) Environmental persistence of a pesticide
B) The lethal dose required to kill 50% of a test animal population
C) The solubility of a pesticide in water
D) The half-life of a pesticide in soil
Correct Answer: B
Rationale: LD50 (Lethal Dose 50%) is a standard measure of acute toxicity. A
lower LD50 value indicates higher toxicity—less pesticide is needed to kill half the
test animals. This helps classify pesticides into toxicity categories that determine
signal words and PPE requirements. A pesticide with a high LD50 value is
generally less toxic than one with a low LD50.
Question 8
Which federal regulation protects agricultural workers and handlers from
occupational pesticide exposure?
A) FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act)
B) Worker Protection Standard (WPS)
C) Endangered Species Act (ESA)
D) Federal Food, Drug, and Cosmetic Act (FFDCA)
Correct Answer: B
Rationale: The Worker Protection Standard (WPS) is a federal regulation aimed at
protecting agricultural employees—including workers and handlers on farms,
forests, nurseries, and greenhouses—from occupational exposure to pesticides.
WPS requires employers to provide training, PPE, decontamination supplies, and
emergency information.

What does "pesticide resistance" refer to?
