Kentucky (KY) Category 3 (Ornamental and Turf
Pest Control) Exam | Latest Verified Questions
and Detailed Answers
OVERVIEW DESCRIPTION:
This comprehensive set of multiple choice questions is designed for the Kentucky Category
3 (Ornamental and Turf Pest Control) Exam, administered by the Kentucky Department of
Agriculture. The content covers integrated pest management (IPM) principles,
identification and management of turfgrass and ornamental pests, proper pesticide
application and safety practices (including drift reduction and pollinator protection), and
Kentucky-specific pesticide laws and regulations such as licensing, record-keeping, and
container disposal.
QUESTION 1
Which of the following is the correct first step in an Integrated Pest Management (IPM)
program for ornamental and turf pests?
A) Selecting the most effective pesticide
B) Correctly identifying the pest
C) Determining the action threshold
D) Releasing natural enemies
CORRECT ANSWER: B) Correctly identifying the pest
EXPERT RATIONALE: Proper pest identification is essential to choose effective, targeted
management strategies and avoid unnecessary pesticide applications. Misidentification
can lead to control failures and harm non-target organisms.
QUESTION 2
An action threshold in IPM is best defined as the point at which:
A) A pesticide application is always made
,2|Page
B) A pest population reaches a level where control is needed to prevent unacceptable
damage
C) Natural enemies begin to appear
D) The pest becomes a public nuisance
CORRECT ANSWER: B) A pest population reaches a level where control is needed to
prevent unacceptable damage
EXPERT RATIONALE: The action threshold balances aesthetic or economic damage
against cost and environmental impact, guiding decisions before unacceptable harm
occurs.
QUESTION 3
Which IPM control tactic involves adjusting irrigation timing to reduce leaf wetness and
discourage fungal diseases in turfgrass?
A) Mechanical control
B) Biological control
C) Cultural control
D) Chemical control
CORRECT ANSWER: C) Cultural control
EXPERT RATIONALE: Cultural controls modify the growing environment—such as
irrigation scheduling—to suppress pest establishment and reproduction without
pesticides.
QUESTION 4
Hand-pulling wild violets from a Kentucky lawn is an example of which IPM strategy?
A) Biological control
B) Mechanical control
C) Chemical control
,3|Page
D) Genetic control
CORRECT ANSWER: B) Mechanical control
EXPERT RATIONALE: Mechanical controls physically remove or destroy pests; hand-
pulling is a direct physical removal method suitable for small infestations.
QUESTION 5
Releasing predatory mites to manage spider mites on ornamental shrubs is an
application of:
A) Cultural control
B) Mechanical control
C) Biological control
D) Host resistance
CORRECT ANSWER: C) Biological control
EXPERT RATIONALE: Biological control employs natural enemies—predators, parasitoids,
or pathogens—to suppress pest populations in an environmentally compatible manner.
QUESTION 6
Which practice is a cultural control method for reducing white grub populations in a
lawn?
A) Spraying imidacloprid in July
B) Aerating and overseeding with endophyte-enhanced tall fescue
C) Applying milky spore powder
D) Flooding the soil for two weeks
CORRECT ANSWER: B) Aerating and overseeding with endophyte-enhanced tall fescue
EXPERT RATIONALE: Endophytic grasses produce alkaloids that deter insect feeding,
providing a built-in cultural defense against grubs and sod webworms.

QUESTION 7
Regular scouting and record-keeping of pest numbers primarily support which IPM
component?
A) Choosing nozzle type
B) Pesticide resistance prevention
C) Determining if pest populations exceed action thresholds
D) Container disposal compliance
CORRECT ANSWER: C) Determining if pest populations exceed action thresholds
EXPERT RATIONALE: Monitoring data allow applicators to make informed decisions
about when intervention is warranted, avoiding unnecessary treatments.
QUESTION 8
Which statement about pesticide use within an IPM program is most accurate?
A) Pesticides are the first line of defense
B) Pesticides are used only after non-chemical methods are deemed insufficient
C) Broad-spectrum insecticides are preferred to cover all possible pests
D) Pesticide selection disregards natural enemy preservation
CORRECT ANSWER: B) Pesticides are used only after non-chemical methods are deemed
insufficient
EXPERT RATIONALE: In IPM, chemical controls are integrated as a last resort when
biological, cultural, and mechanical methods fail to keep pests below the action
threshold.
QUESTION 9
A turf manager notices minor leaf spot on a few bluegrass blades. Scouting shows low
humidity predicted. The best IPM-based response is to:
A) Immediately apply a broad-spectrum fungicide
