1. What is the primary objective of an integrated pest management
(IPM) program for turfgrass?
A. Eliminate all insects from the turf
B. Apply pesticides on a fixed calendar schedule
C. Manage pests at acceptable levels using a combination of
strategies
D. Spray pesticides after every mowing
Rationale: IPM combines cultural, biological, mechanical, and chemical
methods to keep pest populations below economically or aesthetically
damaging levels while minimizing environmental impact. The goal is
management, not complete eradication.
2. Which turfgrass species is best adapted to cool-season climates
such as Vermont?
, A. Bermudagrass
B. Zoysiagrass
C. St. Augustinegrass
D. Kentucky bluegrass
Rationale: Kentucky bluegrass is a cool-season turfgrass well suited to
Vermont's climate. It performs best under moderate temperatures and
is commonly used for lawns, athletic fields, and parks.
3. Which factor most commonly contributes to turf disease
development?
A. Low humidity
B. Susceptible host, favorable environment, and pathogen
presence
C. High soil pH only
D. Excessive mowing height
Rationale: Disease development depends on the disease triangle,
consisting of a susceptible host, a pathogen, and environmental
conditions favorable for infection.
4. Why is calibration of pesticide application equipment important?
A. To increase pesticide toxicity
B. To reduce mowing time
, C. To ensure the correct amount of pesticide is applied
D. To eliminate the need for PPE
Rationale: Proper calibration ensures pesticides are applied at labeled
rates, improving effectiveness while preventing overapplication,
underapplication, environmental contamination, and legal violations.

6. What is the most reliable method for confirming a turf disease?
A. Turf color alone
B. Calendar date
C. Neighbor's diagnosis
D. Correct identification through inspection and symptoms
Rationale: Accurate identification using symptoms, signs, environmental
conditions, and sometimes laboratory diagnosis is essential before
selecting a management strategy.
, 7. Which mowing practice promotes healthy turf?
A. Removing half the leaf blade each mowing
B. Using dull mower blades
C. Removing no more than one-third of the leaf blade
D. Mowing only once each month
Rationale: Removing no more than one-third of the leaf blade minimizes
stress, supports vigorous growth, and reduces disease susceptibility.
8. Which pest primarily feeds on turfgrass roots?
A. Armyworms
B. Cutworms
C. Sod webworms
D. White grubs
Rationale: White grubs feed below ground on roots, weakening turf and
making it susceptible to drought stress and animal damage.
9. Why should pesticide labels always be read before application?
A. Labels are optional suggestions
B. Labels apply only to commercial applicators
C. The label provides legal directions for safe and effective use
D. Labels only contain manufacturer advertisements
