1. What is the primary purpose of Integrated Pest Management
(IPM)?
A. Eliminate all pests immediately using chemicals
B. Use a combination of methods to manage pests economically
and safely
C. Rely only on biological control methods
D. Prevent pest inspection by regulatory agencies
Answer: B
Rationale: IPM focuses on combining cultural, biological, mechanical,
and chemical methods to manage pests in a cost-effective and
environmentally responsible way.
2. Which pesticide formulation is most likely to be inhaled as a fine
mist?
A. Granules
B. Dusts
C. Wettable powders
D. Baits
,Answer: B
Rationale: Dust formulations are lightweight and easily become
airborne, increasing inhalation risk.

absorption?
A. Emulsifiable concentrate
