1. What is the primary purpose of Integrated Pest Management (IPM) in
ornamental pest control?
A. Eliminate every insect from a landscape
B. Use the strongest pesticide available
C. Manage pests effectively while minimizing risks to people and the
environment
D. Apply pesticides on a fixed weekly schedule
Answer: Manage pests effectively while minimizing risks to people and the
environment
Rationale: IPM emphasizes monitoring, accurate identification, prevention,
cultural practices, and carefully selected controls while reducing unnecessary
pesticide use.
2. Before deciding how to manage an ornamental pest, what should an
applicator determine first?
,A. Which pesticide is most expensive
B. What pest or problem is actually present
C. How often the landscape is irrigated
D. Whether the plant has been recently fertilized
Answer: What pest or problem is actually present
Rationale: Correct identification is fundamental because different pests and
plant disorders require different management approaches.
3. Which document legally governs the use of a pesticide product?
A. Advertising brochure
B. Applicator's personal notes
C. Sales receipt
D. The pesticide label
Answer: The pesticide label
Rationale: The pesticide label provides legally enforceable directions,
precautions, restrictions, and other requirements for product use.
4. What does IPM emphasize before pesticide treatment?
A. Routine calendar applications
B. Monitoring and determining whether intervention is necessary
C. Treating every plant in the area
D. Increasing pesticide concentration
Answer: Monitoring and determining whether intervention is necessary
Rationale: IPM uses monitoring and pest-management thresholds to determine
whether control is warranted rather than automatically treating.
5. Which factor can contribute to pesticide drift?
,A. Properly maintained equipment
B. Following label restrictions
C. Unfavorable wind conditions
D. Accurate application
Answer: Unfavorable wind conditions
Rationale: Wind can move pesticide droplets or particles away from the
intended treatment area, potentially exposing people, plants, animals, or water
resources.
6. What is the best general approach to protecting pollinators?
A. Treat flowering plants whenever insects are present
B. Ignore flowering status
C. Use practices that minimize exposure of pollinators to pesticides
D. Apply pesticides whenever bees are nearby
Answer: Use practices that minimize exposure of pollinators to pesticides
Rationale: Pollinator protection involves recognizing flowering plants, avoiding
unnecessary exposure, and following all applicable label precautions and
restrictions.
7. What is pesticide resistance?
A. A plant's ability to survive drought
B. An applicator's ability to tolerate pesticide odors
C. A pest population's reduced susceptibility to a pesticide that previously
controlled it
D. A pesticide becoming stronger after storage
Answer: A pest population's reduced susceptibility to a pesticide that previously
controlled it
, Rationale: Resistance develops in pest populations when individuals with traits
allowing survival reproduce and become more common.
8. Which practice helps reduce pesticide resistance?
A. Repeatedly using the same mode of action
B. Applying unnecessary treatments
C. Using integrated pest management and rotating effective modes of action
when appropriate
D. Increasing applications whenever pests are observed
Answer: Using integrated pest management and rotating effective modes of
action when appropriate
Rationale: IPM reduces selection pressure, while appropriate mode-of-action
rotation can help slow development of resistance.
9. Which condition is most likely to indicate that an ornamental plant problem
may not be caused by an insect?
A. Presence of chewing insects
B. Visible insect feeding
C. Symptoms occurring without evidence of a pest and associated with
environmental stress
D. Presence of insect eggs
Answer: Symptoms occurring without evidence of a pest and associated with
environmental stress
Rationale: Nutritional, environmental, physiological, and disease-related
problems can resemble insect damage and should be considered during
diagnosis.
