1. What is the primary purpose of Integrated Pest
Management (IPM)?
A. Eliminate every pest immediately
B. Prevent all pesticide use
C. Manage pests effectively while minimizing risks
D. Apply pesticides on a fixed schedule
Answer: _C. Manage pests effectively while minimizing
risks**_
Rationale: IPM combines monitoring, prevention, and
appropriate control methods while minimizing unnecessary
pesticide use.
2. Which step should generally occur before selecting a
pesticide?
A. Increase the application rate
B. Identify the pest
,C. Mix the pesticide
D. Purchase PPE
Answer: _B. Identify the pest**_
Rationale: Correct pest identification is essential for selecting
an effective and appropriate management strategy.
3. What is a treatment threshold?
A. The maximum amount of pesticide that can be stored
B. The pest population level at which control action is justified
C. The concentration of pesticide in groundwater
D. The legal pesticide residue limit
Answer: _B. The pest population level at which control action
is justified**_
Rationale: A treatment threshold helps determine when pest
control should begin based on economic, health, aesthetic, or
other concerns.
4. Which is an example of cultural pest control?
A. Applying an insecticide
B. Releasing a predator
C. Changing irrigation practices
D. Trapping insects with pheromones

8. A pesticide application fails because the wrong pest was
identified. Which principle was violated?
A. Proper pest identification
B. Proper storage
C. Proper disposal
D. Proper recordkeeping
Answer: _A. Proper pest identification**_
Rationale: Misidentification can result in ineffective treatment
