1. Which of the following best describes the primary objective of turf
pest management in a commercial pesticide applicator program?
A. Eliminate all living organisms in turf areas permanently
B. Maintain pest populations below economic and aesthetic injury
thresholds
C. Apply pesticides on a fixed calendar schedule regardless of pest
presence
D. Maximize pesticide use to ensure complete weed eradication
The correct objective of turf pest management is to maintain pest
populations below economic and aesthetic injury thresholds, emphasizing
integrated pest management principles rather than complete eradication
or routine unnecessary applications.
2. In turfgrass systems, which practice is most central to Integrated Pest
Management (IPM)?
A. Routine pesticide application without scouting
B. Relying solely on chemical control methods
, C. Monitoring pest populations and using thresholds to guide control
decisions
D. Applying broad-spectrum pesticides at maximum label rates
IPM is centered on monitoring pest populations and using established
thresholds to determine when control measures are necessary, reducing
unnecessary pesticide applications.
3. Which turfgrass species is most commonly associated with high heat
tolerance and aggressive spreading via stolons and rhizomes in Texas
lawns?
A. Kentucky bluegrass
B. Perennial ryegrass
C. Bermudagrass
D. Fine fescue
Bermudagrass is highly adapted to hot climates like Texas and spreads
aggressively through stolons and rhizomes, making it ideal for high-use
turf areas.
4. What is the primary reason pre-emergent herbicides are applied in turf
management?
A. To kill mature perennial weeds after emergence
B. To prevent seed germination of annual weeds
C. To improve turf color and density
D. To increase soil nutrient availability
Pre-emergent herbicides work by preventing weed seeds from
germinating, making them essential for controlling annual weeds like
crabgrass before emergence.
5. Which pest is most commonly responsible for irregular brown patches
in warm-season turf caused by sap-feeding activity?
A. White grubs
, B. Chinch bugs
C. Armyworms
D. Sod webworms
Chinch bugs feed on plant sap in warm-season grasses, leading to irregular
brown patches and turf decline.
6. A key characteristic of white grub damage in turfgrass is:
A. Leaves with chewing holes
B. Turf that lifts easily like a carpet
C. Circular rings of mushrooms
D. Uniform yellowing from nitrogen deficiency
White grubs feed on turf roots, causing the grass to detach easily from the
soil and lift like a carpet.
7. Which herbicide type selectively controls broadleaf weeds while
leaving most turfgrasses unharmed?
A. Glyphosate
B. 2,4-D
C. Paraquat
D. Diquat
2,4-D is a selective herbicide that targets broadleaf weeds while sparing
most turfgrass species.
8. What is the most important environmental condition contributing to
fungal diseases such as brown patch in turf?
A. Cool, dry conditions
B. Hot, humid weather with excess moisture
C. Low soil fertility only
D. High wind and drought
Hot, humid conditions with excessive moisture strongly promote fungal
diseases such as brown patch in turfgrass.
