Tennessee Category 3 Ornamental & Turfgrass Pest Control
Exam
Question 1
A commercial pesticide applicator in Tennessee is preparing to treat a
commercial turfgrass area adjacent to a freshwater pond. According to
state and federal regulations, which of the following label parameters
dictates the legal distance from the water's edge at which the pesticide
can be safely applied?
A. The signal word located on the front panel of the label.
B. The specific buffer zone restrictions found under the environmental
hazards section.
C. The chemical classification of the active ingredient within the safety
data sheet.
D. The target application rate specified in the turf maintenance section.
[1]
Correct Answer: B. The specific buffer zone restrictions
found under the environmental hazards section.
Rationale: The environmental hazards section of a pesticide label
explicitly provides mandatory instructions regarding water
contamination risks, runoff prevention, and specific buffer zones
(setback distances) required to protect non-target aquatic organisms
and water resources. Adhering to these distances is a legal requirement
,under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
and Tennessee state pesticide laws. Signal words indicate acute human
toxicity, not environmental distances. Target rates dictate volume per
area, not proximity boundaries. [1]
Question 2
Under the Tennessee Insecticide, Fungicide, and Rodenticide Act
(TIFRA), commercial applicators must maintain accurate pesticide
application records. For how long must these specific commercial
application records be kept from the date of the application?
A. 6 months
B. 1 year
C. 2 years
D. 5 years [1]
Correct Answer: C. 2 years.
Rationale: Tennessee state law requires all commercial pesticide
applicators to maintain detailed records of both general-use and
restricted-use pesticide applications for a minimum of two years. These
records must be complete and readily available for inspection by
representatives of the Tennessee Department of Agriculture (TDA) to
ensure compliance with environmental and public safety standards. [1]
Question 3
An applicator is treating an ornamental landscape beds area infested
with Japanese beetles (Popillia japonica). The applicator notes that the
pesticide label features the "Bee Hazard" icon within a box. This specific
visual anchor indicates that the applicator must avoid applying the
chemical under which of the following conditions?
A. When the soil temperature falls below 50 degrees Fahrenheit.
B. While the target ornamental plants are actively in bloom during
daylight hours.
C. If the relative humidity drops below 30 percent during application.
D. When applying the product as a deep-root subsurface soil injection.
Correct Answer: B. While the target ornamental plants are
actively in bloom during daylight hours.
Rationale: The "Bee Hazard" icon or warning box on a pesticide label
indicates that the product is highly toxic to honeybees and other
pollinators. It legally prohibits application when target plants or weeds
,are in bloom because foraging bees will come into direct contact with
the pesticide or its residues. Soil temperature, relative humidity, or
subsurface soil injections do not trigger the specific surface bloom
restriction of the pollinator protection box.
Question 4
A technician is calibrating a boom sprayer for a large turfgrass
application in middle Tennessee. If the technician increases the forward
speed of the tractor from 3 miles per hour (mph) to 6 miles per hour
(mph) while maintaining the exact same spray pressure and nozzle size,
what will happen to the pesticide application rate per acre?
A. The application rate per acre will double.
B. The application rate per acre will remain completely unchanged.
C. The application rate per acre will be reduced by half.
D. The application rate per acre will increase by four times.
Correct Answer: C. The application rate per acre will be
reduced by half.
Rationale: Pesticide application volume per unit area is inversely
proportional to travel speed. If the forward speed is exactly doubled
(from 3 mph to 6 mph) while the output from the nozzles remains
constant, the sprayer will cover twice the surface area in the same
amount of time, thereby cutting the volume of pesticide deposited per
acre in half.
Question 5
Which of the following turfgrass diseases is characterized by small,
circular, straw-colored patches about the size of a silver dollar on closely
mowed turfgrass, commonly showing fine, white, cobweb-like mycelium
in the early morning hours when dew is present?
A. Large Patch (Rhizoctonia solani)
B. Dollar Spot (Clarireedia homoeocarpa)
C. Pythium Blight (Pythium spp.)
D. Fairy Ring (Basidiomycetes)
Correct Answer: B. Dollar Spot (Clarireedia
homoeocarpa).
Rationale: Dollar spot produces characteristic small, bleached,
silver-dollar-sized patches on closely mown turf. In morning dew, the
fine aerial mycelium is highly visible but disappears as the leaves dry.
, Large patch forms much wider, irregular circles. Pythium blight
creates greasy, dark patches that collapse quickly. Fairy ring displays
dark green circles or mushrooms arranged in rings.
Question 6
An applicator is dealing with a severe infestation of crabgrass (Digitaria
spp.) in a tall fescue lawn. To achieve effective control after the crabgrass
has already germinated and emerged from the soil, which of the
following classes of herbicides must be applied?
A. Pre-emergence selective herbicide
B. Post-emergence selective herbicide
C. Pre-emergence non-selective herbicide
D. Post-emergence non-selective herbicide
Correct Answer: B. Post-emergence selective herbicide.
Rationale: Because the crabgrass has already germinated and
emerged, a post-emergence herbicide is required to kill the active weed.
To protect the surrounding tall fescue lawn from being destroyed, the
herbicide must be selective, targeting only specific weed species without
harming the desirable turfgrass. Non-selective herbicides (like
glyphosate) would kill both the crabgrass and the tall fescue. [1]
Question 7
A pesticide label contains the signal word "WARNING." What level of
acute human toxicity does this specific regulatory term signify to the
pesticide handler?
A. Highly toxic or corrosive
B. Moderately toxic
C. Slightly toxic
D. Relatively non-toxic
Correct Answer: B. Moderately toxic.
Rationale: Pesticide labels utilize standardized signal words to
denote acute human toxicity levels. "DANGER" indicates high toxicity
or severe corrosive risks to eyes/skin. "WARNING" denotes moderate
toxicity. "CAUTION" indicates slight toxicity. Understanding these
words allows applicators to select the correct personal protective
equipment (PPE).
