1. Which principle is most central to Integrated Pest Management (IPM)?
A. Routine calendar spraying
B. Complete pest eradication
C. Combining multiple compatible pest control strategies
D. Using only chemical controls
Correct Answer: C
Rationale: IPM focuses on integrating biological, cultural,
mechanical, and chemical methods to manage pests economically
and environmentally.
2. The primary purpose of a pesticide label is to:
A. Advertise the product
B. Provide legal use directions and safety information
, C. Increase sales
D. Replace training manuals
Correct Answer: B
Rationale: The label is a legal document that gives directions for safe
and effective use and must be followed by law.
3. In research pest control trials, a “control plot” is used to:
A. Increase pesticide dose accuracy
B. Compare treated vs untreated conditions
C. Eliminate pest resistance
D. Store pesticides safely
Correct Answer: B
Rationale: Control plots are untreated areas used as a baseline for
evaluating treatment effectiveness.
4. Which PPE is MOST important when handling concentrated
pesticides?
A. Sunglasses
B. Cotton gloves
C. Chemical-resistant gloves
D. Baseball cap
Correct Answer: C
Rationale: Chemical-resistant gloves prevent dermal exposure to
concentrated pesticides, which is a major exposure route.
,5. What is the main advantage of randomized plot design in research?
A. Reduces need for replication
B. Eliminates all pests
C. Reduces bias in experimental results
D. Increases pesticide toxicity
Correct Answer: C
Rationale: Randomization reduces experimental bias and ensures
more reliable and valid results.
6. Calibration of application equipment ensures:
A. Higher pesticide toxicity
B. Correct application rate
C. Faster spraying speed
D. Reduced need for PPE
Correct Answer: B
Rationale: Calibration ensures the correct amount of pesticide is
applied per unit area.
7. A pesticide “LD50” refers to:
A. Legal dosage limit
B. Lethal dose for 50% of test organisms
C. Label direction number
D. Lowest dilution factor
Correct Answer: B
, Rationale: LD50 measures acute toxicity by identifying the dose that
kills 50% of test subjects.
8. Drift reduction is MOST important when:
A. Applying indoors
B. Spraying in still air only
C. Using herbicides near sensitive crops
D. Mixing pesticides
Correct Answer: C
Rationale: Drift can damage nearby sensitive plants and contaminate
non-target areas.
9. Which factor most affects pesticide efficacy in field trials?
A. Color of sprayer
B. Weather conditions
C. Brand of tractor
D. Time of day only
Correct Answer: B
Rationale: Weather such as wind, temperature, and humidity
strongly influence pesticide performance.
10. The term “formulation” refers to:
A. Pest resistance level
B. Chemical structure only
C. Mixture of active and inert ingredients
D. Spray nozzle type
