SECTION ONE: QUESTIONS 1–100
Question 1
What is the primary federal law that regulates the sale, distribution, and use of pesticides in the United

C. The Endangered Species Act
D. The Occupational Safety and Health Act
,🟢 B. The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
🔴 Explanation: FIFRA is the cornerstone of federal pesticide regulation, providing the statutory basis
for the EPA to oversee the registration, labeling, and use of all pesticides in the U.S.
Question 2
Under Washington State law, which agency is primarily responsible for enforcing pesticide regulations?
A. Washington State Department of Ecology
B. Washington State Department of Agriculture (WSDA)
C. Washington State Department of Health
D. Washington State Department of Labor and Industries
🟢 B. Washington State Department of Agriculture (WSDA)
🔴 Explanation: WSDA is the lead agency in Washington for enforcing pesticide laws, including
applicator licensing, product registration, and investigating pesticide misuse, as established in state
law (RCW 15.58).
Question 3
What is the primary purpose of a pesticide label, according to both federal and state law?
A. To advertise the product's effectiveness against pests
B. To serve as a legal document that provides instructions and limitations for use
C. To list the manufacturer's contact information
D. To provide a list of all inert ingredients
🟢 B. To serve as a legal document that provides instructions and limitations for use
🔴 Explanation: The pesticide label is legally binding. It is a contract between the manufacturer, the
EPA, and the user, specifying the approved uses, rates, safety precautions, and application methods.
Using a pesticide in a manner inconsistent with its label is a violation of federal and state law.
Question 4
A pesticide applicator is applying a product in a location where they see a pollinator habitat. According
to WPS and best practices, what should they do?
A. Apply the pesticide as planned, as the label only requires a general warning.
B. Ignore the habitat, as pollinators are not affected by most pesticides.
C. Check the pesticide label for specific precautions regarding pollinators and application timing.
D. Remove the habitat before applying the pesticide.
🟢 C. Check the pesticide label for specific precautions regarding pollinators and application timing.
🔴 Explanation: The label is the primary source of information. It will contain specific use instructions,
restrictions, and warnings, including those for protecting pollinators. Applicators are legally obligated
to follow these instructions.
,Question 5
Which of the following is NOT a required element of the Worker Protection Standard (WPS)?
A. Providing decontamination supplies to handlers and early-entry workers
B. Displaying a pesticide safety poster at a central location
C. Training workers and handlers annually
D. Mandating that all workers wear full hazmat suits regardless of the pesticide's toxicity
🟢 D. Mandating that all workers wear full hazmat suits regardless of the pesticide's toxicity
🔴 Explanation: WPS does not mandate the most extreme PPE for all tasks. The specific PPE required is
based on the pesticide label requirements and the task. WPS mandates training, decontamination
supplies, pesticide safety posters, and oral warnings, among other things.
Question 6
When must a Washington State commercial pesticide applicator recertify their license?
A. Every year
B. Every two years
C. Every five years
D. Only when the law changes
🟢 C. Every five years
🔴 Explanation: In Washington State, commercial pesticide applicator licenses must be renewed every
five years, which requires completing a certain number of continuing education credits to demonstrate
ongoing competency.
Question 7
What term describes the amount of pesticide that is applied to a specific area?
A. Rate
B. Concentration
C. Dilution
D. Formulation
🟢 A. Rate
🔴 Explanation: The application rate is the specific quantity of pesticide applied per unit area (e.g.,
ounces per acre, pounds per 1000 square feet). This is a critical piece of information found on the
pesticide label.
Question 8
A pest management professional is called to a school to manage a wasp nest. What is their first
priority before applying any pesticide?
A. Notifying the school principal's office
B. Applying the pesticide quickly before children arrive
C. Identifying the pest and evaluating the situation to determine if action is necessary
D. Setting up a perimeter to keep students away
, 🟢 C. Identifying the pest and evaluating the situation to determine if action is necessary
🔴 Explanation: Proper pest identification is the foundational step in any Integrated Pest Management
(IPM) program. It ensures the correct control method is selected and avoids unnecessary or ineffective
pesticide applications. Safety and communication are also paramount, but identification comes first to
guide the entire response.
Question 9
What is a "restricted-use pesticide"?
A. A pesticide that can only be purchased from a specific store
B. A pesticide that is available only to certified applicators or those under their direct supervision
C. A pesticide that requires a prescription from a doctor
D. A pesticide that is highly diluted and poses no risk
🟢 B. A pesticide that is available only to certified applicators or those under their direct supervision
🔴 Explanation: Restricted-use pesticides (RUPs) are classified by the EPA as having the potential to
cause unreasonable adverse effects to the environment or human health. Therefore, they are restricted
to use by or under the direct supervision of a certified applicator.
Question 10
Which of the following is an example of a cultural control method in Integrated Pest Management
(IPM)?
A. Applying a chemical insecticide
B. Releasing beneficial insects
C. Changing the timing of planting to avoid pest infestations
D. Setting up pheromone traps
🟢 C. Changing the timing of planting to avoid pest infestations
🔴 Explanation: Cultural controls are practices that modify the environment or agricultural practices to
reduce pest establishment, reproduction, dispersal, and survival. Altering planting dates is a classic
example. Chemical control, biological control, and trapping fall into other categories of IPM.
Question 11
If a pesticide label states "Wear a long-sleeved shirt and long pants," this is an example of:
A. A recommendation
B. A suggestion
C. A legal requirement
D. A best practice but not mandatory
