1. A technician applies herbicide and notices browning of nearby shrubs. What
likely occurred?
A. Proper application
B. Herbicide drift or volatilization
C. Pest resistance
D. Soil improvement
Answer: B. Herbicide drift or volatilization
Rationale: Movement of herbicide affects non-target plants.

A. Pre-emergent herbicide and cultural practices
B. Ignoring early weeds
C. Overwatering
D. Random mowing
Answer: A. Pre-emergent herbicide and cultural practices
Rationale: Prevention and turf health reduce weed establishment.
,3. A technician sees discolored roots and poor turf growth. What is MOST likely?
A. Root rot disease
B. Wind damage
C. Sunburn
D. Fertilizer overdose only
Answer: A. Root rot disease
Rationale: Root pathogens damage water and nutrient uptake.
4. What is the BEST way to ensure accurate pesticide application?
A. Guessing rates
B. Proper calibration of equipment
C. Increasing spray pressure
D. Using unmeasured mixing
Answer: B. Proper calibration of equipment
Rationale: Calibration ensures correct application rates.

Answer: A. Legal compliance and accuracy tracking
Rationale: Calibration records support accountability and regulatory compliance.
11. A technician notices rapid turf decline with greasy, water-soaked lesions.
What is the MOST likely cause?
A. Bacterial disease
B. Drought stress
C. Nutrient excess
D. Wind burn
Answer: A. Bacterial disease
Rationale: Many bacterial turf diseases produce water-soaked, greasy lesions and
rapid decline.
12. What is the PRIMARY benefit of soil aeration in turf management?
A. Increases compaction
B. Improves water, air, and nutrient movement
C. Promotes pest infestation
D. Reduces oxygen availability
Answer: B. Improves water, air, and nutrient movement
Rationale: Aeration reduces compaction and improves root health.
