PRACTICE EXAM PREP | PRACTICE EXAM | ALL QUESTIONS
AND ANSWERS | A+ GRADED | COMPREHENSIVE EXAM GUIDE
2026/2027
1. Which statement BEST describes the primary scope of Kentucky Category 20 Sports
Turf certification?
A. Applying pesticides to golf-course greens and fairways
B. Applying pesticides to turf on which sports activities occur
C. Applying pesticides inside commercial buildings
D. Applying pesticides exclusively to agricultural crops
Rationale: Category 20 focuses on pesticide applications used to control insects, weeds, and
diseases on turf where sports activities occur. Golf-course applications are outside this
category.
2. A sports turf manager discovers a rapidly expanding fungal disease before an important
tournament. What should be the FIRST consideration before selecting a pesticide?
A. The color of the turf
B. The brand name of the pesticide
C. Accurate identification of the causal problem
D. Whether the pesticide has the strongest odor
Rationale: Proper pest or disease identification is essential because treatment should target
the actual cause rather than symptoms alone.
3. Why is pesticide label compliance particularly important on athletic fields?
A. Athletic fields never contain non-target organisms
B. Applications can expose players and other people if improperly conducted
C. Labels apply only to agricultural pesticides
D. Sports turf does not require pesticide records
Rationale: Athletic fields may be used by players, coaches, maintenance personnel, and the
public. Following the label helps minimize exposure and environmental risks.
4. Which pest-management approach BEST represents integrated pest management
(IPM)?
A. Applying pesticides on a fixed weekly schedule regardless of pest pressure
B. Eliminating all insects from the turf
C. Combining monitoring, cultural practices, accurate identification, and pesticide use when
justified
D. Using the highest labeled rate whenever symptoms appear
,Rationale: IPM combines monitoring and multiple control strategies while reserving pesticide
treatment for situations where it is justified.
5. A pesticide applicator notices that wind conditions have increased substantially just
before an application. What is the MOST appropriate response?
A. Increase the spray pressure
B. Continue because the pesticide is already mixed
C. Delay or modify the application according to label requirements and drift risk
D. Add more pesticide to compensate for wind
Rationale: Wind can increase spray drift and off-target exposure. Application should be
conducted only under conditions permitted by the label and appropriate safety practices.
6. What is the PRIMARY purpose of calibrating pesticide application equipment?
A. To increase pesticide toxicity
B. To determine the correct application rate and volume
C. To eliminate the need for personal protective equipment
D. To make the pesticide smell less noticeable
Rationale: Calibration ensures that the equipment delivers the intended amount of pesticide
uniformly and helps prevent under- or over-application.
7. A sports field has several areas of compacted soil and poor drainage. Which condition is
MOST likely to contribute to turf problems?
A. Improved root development
B. Reduced plant stress
C. Poor aeration and excessive moisture
D. Increased nutrient availability
Rationale: Compaction reduces pore space and air movement while poor drainage can keep
soil excessively wet, increasing turf stress and disease susceptibility.
8. Which practice can BEST reduce unnecessary pesticide applications on sports turf?
A. Monitoring pest populations and turf conditions
B. Spraying every field every Monday
C. Treating whenever one insect is observed
D. Increasing pesticide rates whenever turf growth slows
Rationale: Monitoring allows an applicator to determine whether pest pressure justifies
treatment and supports informed IPM decisions.
9. Before mixing a pesticide, the applicator should FIRST:
A. Estimate the concentration by appearance
B. Read and follow the current pesticide label
,C. Remove all PPE
D. Add fertilizer to the spray tank
Rationale: The pesticide label provides legally enforceable directions concerning rates,
mixing, application, hazards, PPE, restrictions, and other requirements.
10. What does pesticide drift refer to?
A. Movement of pesticide away from the intended application site
B. Breakdown of pesticide by sunlight
C. Movement of water through soil
D. Absorption of pesticide by roots
Rationale: Drift occurs when pesticide particles, droplets, vapors, or other forms move away
from the intended target.
11. A field manager wants to apply an herbicide immediately before a youth soccer event.
What should determine whether the application proceeds?
A. Whether the product is inexpensive
B. Whether the turf is green
C. The pesticide label, site restrictions, reentry requirements, and safety conditions
D. Whether spectators have arrived
Rationale: Application timing must comply with the product label and applicable restrictions,
including requirements related to entry and exposure.
12. Which PPE provides protection to the eyes from pesticide splashes?
A. Chemical-resistant gloves
B. Protective eyewear
C. Rubber boots
D. Respirator cartridge
Answer: B
Rationale: Appropriate protective eyewear protects the eyes from splashes, sprays, and other
potential pesticide exposure.
13. Why should pesticide applicators avoid eating or drinking while handling pesticides?
A. It reduces pesticide effectiveness
B. It can create a route for pesticide ingestion
C. It changes the pesticide's pH
D. It increases spray drift
Rationale: Eating and drinking while handling pesticides can transfer residues to the mouth
and create an avoidable ingestion exposure.
, 14. Which situation presents the GREATEST risk of pesticide runoff from an athletic
field?
A. Application to dry soil under appropriate conditions
B. Application immediately before heavy rainfall
C. Application during a calm morning
D. Application according to label directions
Rationale: Heavy rainfall shortly after application can move pesticide residues away from the
treated area through surface runoff.
15. What is the BEST reason to maintain accurate pesticide application records?
A. Records eliminate the need to read labels
B. Records document applications and support regulatory compliance and management
decisions
C. Records guarantee pest elimination
D. Records replace equipment calibration
Rationale: Accurate records provide documentation of pesticide use and can support
regulatory compliance, troubleshooting, and future management decisions.
16. A technician accidentally spills concentrated pesticide on the mixing pad. What should
be done FIRST?
A. Hose the material into the nearest drain
B. Ignore the spill if no one was injured
C. Follow the pesticide label and established spill-response procedures
D. Cover the spill with fertilizer
Answer: C
Rationale: Spill response must be based on the product label, safety procedures, containment
requirements, and appropriate protective measures.
17. Which factor can increase the potential for pesticide leaching into groundwater?
A. Highly permeable soil
B. Thick impermeable clay with no drainage
C. Properly calibrated equipment
D. Accurate application rates
Answer: A
Rationale: Highly permeable soils can allow water and dissolved pesticide residues to move
downward more readily.
18. A turf manager observes yellowing grass after an herbicide application. Which
possibility should be investigated FIRST?
A. Phytotoxicity
