1. A landscape maintenance technician observes yellowing turfgrass and stunted growth in
a high-traffic athletic field. Upon inspection, the technician discovers small, brown, pear-
shaped insects feeding on the grass roots. Which pest is most likely responsible for these
symptoms?
A. Sod webworm
B. Hairy chinch bug
C. Annual bluegrass weevil
D. Japanese beetle grub
White grubs, such as Japanese beetle larvae, feed directly on turfgrass roots, severing them
from the soil and causing drought-like symptoms, yellowing, and loose turf that can be easily
rolled back like a carpet. Sod webworms chew leaf blades above ground; chinch bugs feed on
sap using piercing-sucking mouthparts; and annual bluegrass weevil larvae primarily target
golf course turf.
2. Which Kentucky Department of Agriculture (KDA) license category is specifically
required for commercial applicators applying pesticides to ornamental trees, shrubs, and
flowers in public or commercial landscapes?
A. Category 1A - Agricultural Plant Pest Control
B. Category 3 - Ornamental and Turf Pest Control
C. Category 7 - Structural Pest Control
D. Category 5 - Aquatic Pest Control
Kentucky Category 3 certification is mandatory for individuals applying pesticides to control
pests in turfgrass, shade trees, shrubs, and ornamental plantings in commercial, industrial, or
institutional settings. Category 1A covers agricultural crops, Category 5 covers aquatic
environments, and Category 7 covers structural pests.
,3. A turf manager is calibrating a boom sprayer and determines that the application rate is
too high. Which adjustment will decrease the output volume per acre without changing the
nozzle size or operating pressure significantly?
A. Increase the tractor ground speed
B. Decrease the tractor ground speed
C. Install larger capacity spray tips
D. Increase the pump pressure substantially
Spray volume per area is inversely proportional to ground speed. Increasing travel speed
means the sprayer covers more area in the same amount of time, thereby decreasing the
volume of spray applied per acre. Conversely, decreasing speed, increasing pressure, or using
larger tips increases the application volume.
4. What is the primary advantage of using a systemic insecticide rather than a contact
insecticide for controlling armored scale insects on ornamental shrubs?
A. Systemic insecticides kill target pests instantly upon physical contact on the leaf surface.
B. Systemic insecticides are absorbed and translocated throughout the plant tissues,
protecting new growth where scales feed.
C. Systemic insecticides require no specialized personal protective equipment during mixing.
D. Systemic insecticides have zero persistence and degrade within minutes of application.
Armored scales secrete a hard, protective covering that shields them from many surface-
applied contact sprays. Systemic insecticides move through the plant vascular system, allowing
sap-feeding insects to ingest the toxicant while bypassing the protective external armor.
5. Which weed life cycle classification describes a plant that germinates from seed, develops
foliage and roots, flowers, produces seeds, and completes its entire life cycle within a single
12-month growing season?
A. Biennial weed
B. Perennial weed
C. Annual weed
D. Woody shrub
,Annual weeds complete their life cycle from seed germination to seed production within one
year or growing season. They are further divided into summer annuals and winter annuals.
Biennials require two years, and perennials live for multiple years.
6. When reading a pesticide label, what does the signal word "WARNING" indicate
regarding acute toxicity?
A. The product is relatively non-toxic or has low toxicity.
B. The product is moderately toxic and can cause moderate eye or skin irritation.
C. The product is highly toxic and can cause severe illness or death if swallowed, inhaled, or
absorbed.
D. The product poses no environmental or human health hazards whatsoever.
Pesticide signal words reflect acute toxicity levels. "CAUTION" indicates low toxicity,
"WARNING" indicates moderate toxicity, and "DANGER" indicates high toxicity.
Understanding these categories is vital for selecting appropriate personal protective
equipment.
7. A groundskeeper notices circular patches of dead turfgrass with cottony white mycelium
visible early in the morning during humid, warm weather. Which disease is most
characteristic of these symptoms?
A. Dollar spot
B. Pythium blight
C. Brown patch
D. Necrotic ring spot
Brown patch, caused by the fungus Rhizoctonia solani, often displays a distinctive "smoke
ring" or dark border around circular patches of dying turf during hot, humid weather.
Cottony mycelium is frequently visible in early morning dew before the turf dries out.
8. Which federal agency is primarily responsible for registering pesticide products and
establishing maximum residue limits under the Federal Insecticide, Fungicide, and
Rodenticide Act (FIFRA)?
A. Occupational Safety and Health Administration (OSHA)
B. Environmental Protection Agency (EPA)
C. Federal Trade Commission (FTC)
, D. Department of Transportation (DOT)
Under FIFRA, the EPA regulates the production, sale, distribution, and use of all pesticides in
the United States to protect human health and the environment. State agencies like the KDA
enforce these federal regulations locally.
9. What is the primary purpose of adding a surfactant to a spray tank mixture when
treating waxy-leafed broadleaf weeds with a post-emergent herbicide?
A. To neutralize the pH of the water source completely
B. To reduce surface tension, allowing the spray droplets to spread evenly and adhere
better to waxy leaf cuticles
C. To act as a selective fertilizer for the surrounding turfgrass
D. To freeze the spray mixture instantly in cold weather
Surfactants are surface-active agents that lower the surface tension of water droplets,
preventing them from beading up and rolling off waxy or hairy weed leaves. This maximizes
herbicide absorption and efficacy.
10. Which turfgrass species is classified as a warm-season grass that spreads via stolons
and rhizomes, exhibits excellent heat tolerance, but goes into winter dormancy and turns
straw-brown in Kentucky's climate?
A. Kentucky bluegrass
B. Tall fescue
C. Bermudagrass
D. Perennial ryegrass
Bermudagrass is a warm-season turfgrass well-adapted to southern regions and transition
zones like Kentucky, where it remains green during summer but turns brown during cold
winter months. Kentucky bluegrass, tall fescue, and perennial ryegrass are cool-season
grasses.
11. An applicator is preparing to apply a restricted-use pesticide (RUP) in a commercial
landscape. Which requirement must be met prior to purchase and application?
A. The applicator must possess a valid commercial pesticide applicator license issued by
the state department of agriculture.
