SECTION ONE — QUESTIONS 1–50
1. A turf manager notices irregular brown patches developing on a golf course fairway
during periods of high humidity. What should be the FIRST step before applying a
fungicide?
A. Increase nitrogen fertilization immediately
B. Identify the causal pathogen through proper diagnosis
C. Apply a broad-spectrum insecticide
D. Overseed the damaged turf area
════════════════════
Correct Answer: B. Identify the causal pathogen through proper diagnosis
Rationale:
Proper diagnosis is essential before selecting any pesticide treatment because several turf
disorders can produce similar symptoms. Applying fungicides without identifying the actual
pathogen may waste resources, damage turf health, and contribute to pesticide resistance. The
other options either fail to address the root cause or may worsen the issue.
════════════════════
2. A pesticide applicator accidentally spills concentrated herbicide near a storm drain.
What is the MOST appropriate immediate action?
A. Flush the area with large amounts of water
B. Leave the spill for specialized contractors only
C. Contain the spill using absorbent materials
D. Cover the spill with soil and continue working
════════════════════
Correct Answer: C. Contain the spill using absorbent materials
Rationale:
,Containing the spill immediately helps prevent environmental contamination and protects
water sources. Applicators should use absorbent materials and follow spill response
procedures outlined on the product label and safety plan. Flushing with water may spread
contamination, while ignoring or burying the spill violates environmental protection practices.
════════════════════
3. A homeowner requests treatment for weeds in a lawn located beside a pond. Which
factor is MOST critical when selecting an herbicide?
A. The herbicide’s color
B. The application equipment brand
C. The herbicide’s aquatic use restrictions
D. The lawn mowing schedule
════════════════════
Correct Answer: C. The herbicide’s aquatic use restrictions
Rationale:
Products used near water sources must be specifically labeled for aquatic or shoreline
applications to avoid contamination and harm to aquatic organisms. Applicators must always
follow label restrictions regarding environmental hazards and buffer zones.
════════════════════
4. Which turfgrass management practice MOST helps reduce disease pressure from dollar
spot fungus?
A. Watering late in the evening
B. Maintaining balanced nitrogen fertility
C. Allowing excessive thatch accumulation
D. Mowing with dull blades only
════════════════════
Correct Answer: B. Maintaining balanced nitrogen fertility
Rationale:
Adequate nitrogen fertility helps turf resist dollar spot infections by promoting healthy growth.
Excessive moisture, poor mowing practices, and thatch accumulation can increase disease
pressure rather than reduce it.
════════════════════
,5. During a pesticide application, wind speeds increase unexpectedly to 18 mph. What
should the applicator do?
A. Continue spraying using a higher pressure setting
B. Switch to smaller nozzles and continue
C. Add additional pesticide to improve effectiveness
D. Stop the application to reduce drift risk
════════════════════
Correct Answer: D. Stop the application to reduce drift risk
Rationale:
High winds significantly increase pesticide drift potential, which can damage non-target
plants, contaminate nearby properties, and violate label requirements. Suspending the
application is the safest and legally appropriate action.
════════════════════
6. Which statement BEST describes integrated pest management (IPM)?
A. Applying pesticides on a fixed calendar schedule
B. Eliminating all insects regardless of population levels
C. Combining cultural, biological, mechanical, and chemical controls
D. Using only organic pesticides for pest suppression
════════════════════
Correct Answer: C. Combining cultural, biological, mechanical, and chemical controls
Rationale:
IPM emphasizes a balanced approach that integrates multiple management strategies while
minimizing environmental impact and unnecessary pesticide use. Calendar spraying and total
eradication are inconsistent with IPM principles.
════════════════════
7. A lawn care company employee experiences dizziness while mixing pesticides. What is
the MOST likely cause?
A. Excessive turf irrigation
B. Heat stress or pesticide exposure
C. Improper mowing height
D. Soil compaction issues
, ════════════════════
Correct Answer: B. Heat stress or pesticide exposure
Rationale:
Dizziness during pesticide handling may indicate pesticide exposure, heat exhaustion, or both.
The worker should stop immediately, seek medical evaluation if necessary, and review PPE
and handling procedures.
════════════════════
8. Which nozzle type generally produces the LARGEST spray droplets and reduces drift
potential?
A. Hollow cone nozzle
B. Fine mist nozzle
C. Air-induction nozzle
D. Twin-fan nozzle
════════════════════
Correct Answer: C. Air-induction nozzle
Rationale:
Air-induction nozzles produce larger droplets that are less prone to drift, making them suitable
for many turf and ornamental applications. Fine droplets generated by other nozzle types
increase drift risk.
════════════════════
9. What is the PRIMARY purpose of calibrating pesticide application equipment?
A. To increase pesticide odor
B. To improve fertilizer absorption
C. To reduce mowing frequency
D. To ensure accurate pesticide delivery rates
════════════════════
Correct Answer: D. To ensure accurate pesticide delivery rates
Rationale:
Calibration ensures the correct amount of pesticide is applied uniformly and legally according
to label directions. Improper calibration can result in ineffective control, turf injury, or
environmental contamination.
