1. What is the primary objective of Integrated Pest Management (IPM) in
agricultural plant systems?
A. Eliminate all pests through chemical control only
B. Maximize crop yield regardless of environmental impact
C. Use a combination of biological, cultural, mechanical, and chemical
methods to manage pests economically and sustainably
D. Prevent all pesticide use on agricultural crops
C
IPM emphasizes long-term pest management using multiple
strategies to reduce economic, environmental, and health risks while
maintaining effective crop protection.
2. Under FIFRA regulations, pesticide labels are considered:
A. Marketing suggestions provided by manufacturers
B. Optional guidance for applicators
C. Legal documents that must be followed exactly
D. Educational recommendations only
C
The pesticide label is a legally binding document, and applicators are
, required by law to follow all instructions, restrictions, and
precautions on the label.
3. What does the signal word “Danger” on a pesticide label indicate?
A. Slight toxicity with minimal hazard
B. Moderate toxicity requiring caution
C. High acute toxicity requiring extreme care
D. No toxicity but environmental concern
C
“Danger” is the highest toxicity warning on pesticide labels and often
indicates severe acute hazard or potential skin or eye injury.
4. Which federal law primarily governs pesticide registration and use in
the United States?
A. Clean Water Act
B. Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
C. Endangered Species Act
D. Food Safety Modernization Act
B
FIFRA is the main federal statute regulating pesticide registration,
labeling, distribution, sale, and use to ensure safety and
environmental protection.
5. What is the purpose of a Restricted Entry Interval (REI)?
A. Time required to mix pesticides safely before application
B. Time period that must pass before workers can re-enter treated
areas without protective equipment
C. Time required for pesticide storage before disposal
D. Interval between two consecutive pesticide applications
B
REI ensures worker safety by requiring a waiting period after
pesticide application before re-entry into treated areas is allowed.
6. Which pesticide formulation is most likely to drift during application?
A. Granules
B. Wettable powders
C. Emulsifiable concentrates (ECs)
D. Pellets
C
, Emulsifiable concentrates produce fine spray droplets that increase
the risk of drift compared to heavier or solid formulations.
7. What is the main function of a pre-emergent herbicide?
A. Kill mature weeds after they emerge
B. Prevent weed seed germination and establishment
C. Increase crop nutrient uptake
D. Stimulate plant growth hormones
B
Pre-emergent herbicides act on weed seeds or seedlings before
emergence to prevent establishment in the field.
8. Which factor does NOT influence pesticide effectiveness?
A. Soil organic matter
B. Temperature
C. Color of the applicator
D. Moisture level
C
Applicator characteristics such as clothing color do not affect
pesticide performance, while environmental conditions significantly
influence effectiveness.
9. What is the main purpose of the Worker Protection Standard (WPS)?
A. Regulate pesticide pricing
B. Protect agricultural workers and pesticide handlers from
occupational exposure
C. Control pesticide manufacturing quality
D. Promote pesticide marketing practices
B
WPS establishes safety requirements such as training, PPE, and
restricted entry intervals to protect agricultural workers from
pesticide exposure.
10. Which herbicide type is absorbed through leaves and
transported throughout the plant?
A. Contact herbicide
B. Systemic herbicide
C. Pre-emergent herbicide
D. Soil fumigant
