1. Which statement best defines integrated pest management (IPM) in
ornamental and turf settings?
A. Routine calendar-based pesticide applications
B. Exclusive reliance on biological control
C. A decision-making process that combines multiple control strategies
based on monitoring and thresholds
D. Eliminating all pests regardless of economic impact
Answer: C
Integrated pest management (IPM) is a systematic decision-making
approach that integrates cultural, biological, mechanical, and chemical
methods based on pest monitoring and economic or aesthetic
thresholds. It avoids unnecessary pesticide applications and promotes
long-term prevention.
,2. In Utah turfgrass systems, cool-season grasses such as Kentucky
bluegrass grow most actively during:
A. Mid-summer heat
B. Late fall and early spring
C. Mid-winter dormancy
D. Periods of drought
Answer: B
Cool-season grasses thrive in moderate temperatures typical of early
spring and fall in Utah. During hot summers, growth slows and stress
increases, making proper irrigation and management critical.
3. The primary purpose of preemergent herbicides in turf is to:
A. Kill mature weeds
B. Prevent weed seed germination
C. Fertilize turf
D. Improve soil structure
Answer: B
Preemergent herbicides create a chemical barrier that inhibits
germinating weed seeds. They are most effective when applied before
weed emergence and activated by irrigation or rainfall.
,4. Which factor most influences pesticide drift during application?
A. Soil pH
B. Wind speed
C. Turf color
D. Fertility level
Answer: B
Wind speed is a major factor in pesticide drift. Applications should be
avoided during high winds to prevent off-target movement and
potential environmental contamination.
5. A systemic insecticide differs from a contact insecticide because it:
A. Remains only on leaf surfaces
B. Is absorbed and translocated within the plant
C. Is less toxic
D. Requires no PPE
Answer: B
Systemic insecticides are absorbed by plant tissues and transported
internally, allowing them to control pests feeding within or on plant
tissues. Contact insecticides require direct contact with the pest.
, 6. Dollar spot disease in turfgrass is most commonly associated with:
A. Excess nitrogen
B. Low nitrogen fertility
C. High mowing height
D. Excess irrigation only
Answer: B
Dollar spot frequently develops in turf with inadequate nitrogen. Proper
fertility management reduces disease susceptibility.
7. The label statement “Restricted Use Pesticide” indicates:
A. It is safe for homeowners
B. Only certified applicators may purchase and apply it
C. It requires no recordkeeping
D. It may be used without supervision
Answer: B
Restricted Use Pesticides (RUPs) require certification due to potential
risks to human health or the environment. Applicators must maintain
records and follow strict compliance standards.
