1. Which of the following best describes the purpose of integrated pest
management (IPM)?
A. To eliminate all pests from a crop
B. To apply pesticides on a fixed schedule
C. To combine multiple control methods for sustainable pest suppression
D. To rely exclusively on chemical control methods
Answer: C
IPM combines biological, cultural, mechanical, and chemical control strategies to
manage pests effectively while minimizing environmental and economic risks.
2. The term “economic threshold” refers to:
A. The maximum amount of pesticide that can be applied legally
B. The pest density at which control measures should be initiated
C. The number of natural enemies present in a crop
D. The total yield loss due to pest damage
Answer: B
The economic threshold is the point at which pest control action should begin to
prevent an increasing pest population from reaching the economic injury level.
3. Which pesticide formulation is least likely to drift during application?
A. Dust
B. Emulsifiable concentrate
,C. Granule
D. Aqueous solution
Answer: C
Granular formulations are heavier and less prone to drift compared to dusts or
sprays.
4. What is the main advantage of biological pest control?
A. Immediate pest eradication

C. No need for monitoring
D. Elimination of pesticide resistance
Answer: B

7. Which soil factor most affects the leaching potential of pesticides?
A. Color
B. Texture
C. Temperature
D. Bulk density
Answer: B
Soil texture affects water movement—sandy soils promote leaching more than
clay soils.
8. Drift can be reduced by:
A. Increasing spray pressure
B. Using smaller nozzles
C. Spraying in windy conditions
D. Lowering spray pressure and using larger droplets
Answer: D
Larger droplets and reduced pressure minimize drift.
9. Restricted-use pesticides can be applied by:
A. Anyone over 18
B. Only licensed or certified applicators
C. Homeowners with supervision
