1. In the context of landscape pest management, which of the following
best defines an integrated pest management (IPM) approach as
applied to ornamental landscapes?
A. Routine pesticide application regardless of pest presence
B. Exclusive reliance on biological control agents
C. A combination of cultural, biological, mechanical, and chemical
methods based on monitoring and thresholds
D. Elimination of all pests without regard to environmental impact
Rationale: IPM emphasizes a holistic strategy that integrates multiple
control methods and relies on monitoring pest populations to determine
when action is necessary, reducing unnecessary pesticide use.
2. Which factor is most critical when selecting a pesticide for use in
landscaped areas with high public exposure?
A. Lowest purchase price
B. Highest toxicity to target pest
C. Lowest risk to humans, pets, and non-target organisms
D. Longest residual activity
,Rationale: In public landscapes, minimizing risk to people, pets, and
beneficial organisms is the primary concern when choosing a pesticide.
3. What is the primary purpose of calibrating pesticide application
equipment?
A. To increase pesticide toxicity
B. To reduce labor costs
C. To ensure accurate delivery of the correct pesticide rate
D. To improve product shelf life
Rationale: Calibration ensures the correct amount of pesticide is applied,
preventing under- or over-application which can lead to poor control or
environmental harm.
4. Which of the following is a common symptom of herbicide drift injury
in landscape plants?
A. Uniform plant growth
B. Increased flowering
C. Distorted or cupped leaves
D. Deep green coloration
Rationale: Herbicide drift often causes abnormal growth patterns such as
cupping, twisting, or distortion of leaves.
5. What is the best time to apply pre-emergent herbicides for annual
weed control in landscapes?
A. After weeds have fully matured
B. During peak flowering
C. Before weed seeds germinate
D. At the end of the growing season
Rationale: Pre-emergent herbicides must be applied before weed seeds
germinate to be effective.
6. Which pest is most commonly associated with causing stippling
damage on ornamental plant leaves?
A. Caterpillars
, B. Beetles
C. Spider mites
D. Slugs
Rationale: Spider mites feed by piercing plant cells, causing a stippled or
speckled appearance.
7. What is the primary function of a surfactant in pesticide applications?
A. Increase toxicity
B. Reduce evaporation
C. Improve pesticide spread and adhesion on plant surfaces
D. Neutralize active ingredients
Rationale: Surfactants help pesticides spread evenly and stick to plant
surfaces, improving efficacy.
8. Which type of nozzle is most appropriate for minimizing pesticide drift
during application?
A. Hollow cone nozzle
B. Flat fan nozzle
C. Low-pressure, large-droplet nozzle
D. Mist blower nozzle
Rationale: Larger droplets reduce drift potential compared to fine sprays.
9. What is the economic threshold in pest management?
A. Level at which pests cause plant death
B. Cost of pesticide application
C. Pest population level at which control measures should be
implemented
D. Maximum allowable pesticide residue
Rationale: The economic threshold indicates when pest control actions are
justified to prevent unacceptable damage.
10. Which of the following is a sign of fungal disease in landscape
plants?
