Plus Rationale 2027 Q&A| Instant Download Pdf
1. What is the primary objective of an integrated pest management
(IPM) program in turfgrass?
A. Eliminate all insects permanently
B. Use pesticides on a fixed schedule
C. Manage pests economically while minimizing risks to people
and the environment
D. Increase fertilizer applications
Rationale: IPM combines cultural, biological, mechanical, and chemical
methods to maintain pests below damaging levels while reducing
environmental impacts, protecting beneficial organisms, and minimizing
unnecessary pesticide use.
2. Which turfgrass species is classified as a warm-season grass?
A. Kentucky bluegrass
B. Tall fescue
C. Perennial ryegrass
D. Bermudagrass
,Rationale: Bermudagrass thrives during warm weather and enters
dormancy in cooler months. Kentucky bluegrass, perennial ryegrass, and
tall fescue are cool-season grasses commonly grown in Virginia.
3. Which factor most influences pesticide drift?
A. Soil pH
B. Fertilizer rate
C. Wind speed
D. Turf color
Rationale: Wind speed significantly affects off-target movement of
pesticide droplets. Applicators should avoid spraying during excessive
winds to minimize drift and protect nearby people, plants, and water
sources.
4. What is the best time to irrigate turf after applying most
preemergence herbicides?
A. One week later
B. During heavy rainfall
C. Shortly after application according to label directions
D. Never irrigate
Rationale: Most preemergence herbicides require light irrigation soon
after application to move the active ingredient into the soil where weed
seeds germinate. Always follow label instructions.
, 5. Annual bluegrass is scientifically known as:
A. Cynodon dactylon
B. Festuca arundinacea
C. Poa annua
D. Lolium perenne
Rationale: Poa annua is a common winter annual weed found in
turfgrass and is known for prolific seed production and light green
coloration.
6. Which pest commonly causes irregular brown patches by feeding
on turfgrass roots?
A. Sod webworms
B. Chinch bugs
C. White grubs
D. Aphids
Rationale: White grubs feed below ground on roots, reducing water
uptake and causing turf to wilt and peel away easily from the soil.
7. Which equipment component primarily determines spray droplet
size?
A. Pressure gauge
B. Hose length
, C. Tank lid
D. Spray nozzle
Rationale: Nozzle design and operating pressure determine droplet size,
affecting coverage, drift potential, and application efficiency.
8. Which disease commonly produces dollar-sized straw-colored
patches on golf course turf?
A. Brown patch
B. Leaf spot
C. Dollar spot
D. Rust
Rationale: Dollar spot produces small, circular, straw-colored lesions
approximately the size of a silver dollar, especially on closely mowed
turf.
9. Why is calibration of application equipment important?
A. To reduce mowing frequency
B. To ensure the correct pesticide rate is applied
C. To sharpen mower blades
D. To improve irrigation
Rationale: Proper calibration ensures accurate pesticide delivery,
preventing ineffective control, crop injury, environmental
contamination, and label violations.
