1. Which statement best describes the primary objective of an Integrated
Pest Management (IPM) program in ornamental, turf, and landscape
pest control operations across Canadian commercial settings?
A. To eradicate every pest organism from the managed landscape
regardless of cost or environmental impact
B. To rely exclusively on biological control agents for long-term pest
suppression
C. To combine cultural, biological, mechanical, and chemical methods
to maintain pests below damaging thresholds
D. To maximize pesticide applications during peak growing seasons to
prevent any visible pest injury
C. To combine cultural, biological, mechanical, and chemical methods to
maintain pests below damaging thresholds
Integrated Pest Management emphasizes the coordinated use of multiple
pest management strategies to keep pest populations below economically
,or aesthetically damaging levels while minimizing environmental risks,
pesticide resistance, and unnecessary pesticide use.
2. A commercial pesticide applicator notices circular brown patches
developing on a golf course putting green during periods of high
humidity and warm nighttime temperatures. Which turf disease is
most commonly associated with these conditions?
A. Snow mold
B. Dollar spot
C. Brown patch
D. Fairy ring
C. Brown patch
Brown patch disease, caused by Rhizoctonia species, commonly develops
during warm, humid conditions with prolonged leaf wetness and high
nighttime temperatures, especially on intensively managed turfgrass areas
such as putting greens.
3. Which factor is most important when calibrating a boom sprayer used
for ornamental shrub applications?
A. The age of the pesticide container
B. The color of the spray solution
C. The relationship among nozzle output, travel speed, and spray
width
D. The total number of shrubs treated per hectare
C. The relationship among nozzle output, travel speed, and spray width
Proper sprayer calibration depends on accurately measuring nozzle
discharge, equipment travel speed, and spray coverage width to ensure
the correct pesticide rate is applied uniformly across the target area.
4. Which turfgrass management practice most effectively reduces the
likelihood of fungal disease development in highly maintained turf
areas?
A. Frequent shallow irrigation during evening hours
, B. Maintaining excessive nitrogen fertility throughout the season
C. Improving air circulation and watering deeply during early morning
hours
D. Cutting turf at the lowest possible mowing height year-round
C. Improving air circulation and watering deeply during early morning
hours
Deep, infrequent morning irrigation and improved air circulation reduce
prolonged leaf wetness, which limits fungal pathogen development and
promotes healthier turf growth.
5. In ornamental landscape pest management, the term “phytotoxicity”
refers to:
A. The resistance of weeds to herbicides
B. Toxic effects of pesticides on desirable plants
C. The toxicity of fertilizers to soil microbes
D. Plant diseases caused by fungi and bacteria
B. Toxic effects of pesticides on desirable plants
Phytotoxicity occurs when pesticides injure desirable plants, causing
symptoms such as leaf burn, discoloration, stunting, or deformation due to
improper application rates, environmental conditions, or plant sensitivity.
6. Which statement concerning pesticide drift is most accurate?
A. Drift only occurs during aerial pesticide applications
B. Drift cannot occur when low-pressure nozzles are used
C. Drift risk increases with small droplet size and high wind velocity
D. Drift is eliminated when granular pesticides are applied
C. Drift risk increases with small droplet size and high wind velocity
Small spray droplets remain airborne longer and are more easily carried by
wind currents, increasing the potential for off-target movement and
environmental contamination.
, 7. A pesticide applicator treating ornamental trees near a water feature
should primarily select a pesticide formulation that:
A. Has the highest odor threshold
B. Is highly volatile for rapid dispersion
C. Minimizes potential contamination of aquatic ecosystems
D. Requires the greatest number of repeat applications
C. Minimizes potential contamination of aquatic ecosystems
Applications near aquatic environments require formulations and practices
that reduce runoff, leaching, and toxicity to aquatic organisms in order to
protect sensitive ecosystems.
8. Which insect pest commonly damages ornamental trees by feeding
beneath the bark and disrupting nutrient transport tissues?
A. Aphids
B. Bark beetles
C. Leaf miners
D. Thrips
B. Bark beetles
Bark beetles tunnel beneath tree bark and damage vascular tissues,
disrupting water and nutrient movement while often introducing
pathogenic fungi that weaken or kill trees.
9. Why is rotating pesticide modes of action important in turf and
ornamental pest management programs?
A. To improve fertilizer uptake efficiency
B. To increase pesticide volatility
C. To reduce the development of pest resistance
D. To eliminate the need for calibration procedures
C. To reduce the development of pest resistance
