Question 1. **Which term describes the pest population level at which control
measures become economically justified?**
A) Economic Injury Level (EIL)
B) Economic Threshold (ET)
C) Pest Pressure Index (PPI)
D) Damage Severity Rating (DSR)
Answer: B
Explanation: The Economic Threshold (ET) is the pest density at which action
should be taken to prevent the population from reaching the Economic Injury
Level (EIL), where economic loss exceeds control costs.

Question 2. **In Integrated Pest Management, what is the first step in the
decision-making cycle?**
A) Monitoring pest populations
B) Applying chemical controls
C) Scouting fields for pests
D) Evaluating economic impact
Answer: C
Explanation: Scouting involves regularly inspecting crops to detect the presence of
pests, which initiates the IPM decision cycle.

Question 3. **Which of the following is a dry pesticide formulation?**
A) Emulsifiable Concentrate (EC)
B) Flowable (F)
C) Wettable Powder (WP)
D) Microencapsulated (ME)
Answer: C
Explanation: Wettable Powders (WP) are dry, fine particles that must be mixed
with water before application.

Question 4. **On a pesticide label, what does the signal word “DANGER-POISON”
indicate?**
A) Moderate toxicity
B) Low toxicity
C) High acute toxicity, possibly lethal
D) Minimal risk to humans
Answer: C
Explanation: “DANGER-POISON” is the highest toxicity signal word, indicating the
product can cause severe health effects or death if misused.

Question 5. **Which personal protective equipment (PPE) item provides
protection against inhalation of pesticide aerosols?**
A) Chemical-resistant gloves
B) Full-face respirator with P100 filter
C) Long-sleeve coveralls
D) Rubber boots
Answer: B
Explanation: A full-face respirator with a P100 filter removes fine pesticide
particles from the inhaled air, protecting the respiratory system.

Question 6. **What is the most appropriate immediate first-aid step for a worker
who has inhaled pesticide fumes?**
A) Induce vomiting
B) Apply a cold compress to the chest
C) Move the worker to fresh air and seek medical attention
D) Give the worker water to drink
Answer: C
Explanation: Removing the person from the contaminated environment and
providing fresh air reduces exposure; medical evaluation follows.

Question 7. **Which process describes the movement of pesticides from the soil
surface into deeper groundwater layers?**
A) Volatilization
B) Runoff
C) Leaching
D) Drift
Answer: C
Explanation: Leaching is the downward migration of soluble chemicals through
the soil profile into groundwater.
---
Question 8. **When applying a pesticide, which factor most strongly influences
drift potential?**
A) Droplet size produced by the nozzle
B) Soil pH at the time of application
C) Time of day the pesticide was mixed
D) Color of the pesticide tank
Answer: A
Explanation: Smaller droplets are more easily carried by wind, increasing drift;
nozzle selection and pressure control droplet size.
