1. Which federal law primarily governs the regulation of pesticides in the
United States?
A. Clean Air Act
B. Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
C. Resource Conservation and Recovery Act
D. Endangered Species Act
Rationale: FIFRA is the primary federal statute regulating the
registration, distribution, sale, and use of pesticides to protect human
health and the environment.
2. What is the purpose of a pesticide’s label?
A. To provide marketing information
B. To list the price of the pesticide
C. To provide legally enforceable instructions for safe and effective
use
D. To describe the chemical synthesis
, Rationale: The label is a legal document that specifies how a
pesticide must be used, including restrictions and safety precautions
to prevent harm.
3. Which signal word indicates the highest acute toxicity on a pesticide
label?
A. Caution
B. Warning
C. Danger
D. Notice
Rationale: “Danger” indicates the most severe acute toxicity
classification, signaling high potential for harm if misused.
4. What is the primary goal of integrated pest management (IPM) in
industrial weed control?
A. To eliminate all vegetation
B. To use a combination of methods to manage weeds with minimal
environmental impact
C. To apply the maximum amount of herbicide
D. To reduce labor costs only
Rationale: IPM emphasizes strategic use of multiple control tactics to
achieve sustainable weed management while reducing reliance on
pesticides.
5. Which type of herbicide application is most appropriate for controlling
broadleaf weeds in a gravel parking area?
A. Foliar application to turfgrass
B. Directed spray to targeted weeds
C. Broadcast application over soil
D. Aerial application

A. Kill on contact only
B. Translocate within the plant to disrupt physiological processes
C. Evaporate and kill insects
D. Provide a physical barrier on the soil
Rationale: Systemic herbicides move through the plant’s vascular
system to reach roots and shoots, inhibiting growth processes.
7. When applying pesticides near water bodies, what practice minimizes
contamination?
A. Increasing spray pressure
B. Establishing buffer zones and avoiding applications during wind
drift
C. Applying at night only
D. Adding fertilizer to sprays
Rationale: Buffer zones and drift management reduce pesticide entry
into water, protecting aquatic organisms.
8. What is a “spot treatment” in weed control?
A. Treating an entire field
B. Applying herbicide to soil only
C. Targeting small, localized weed infestations
D. Aerial application over large areas
Rationale: Spot treatments focus herbicide application on limited
weed patches to reduce chemical use and environmental impact.
9. Which of the following personal protective equipment (PPE) is
commonly required during herbicide mixing and loading?
A. Hard hat
