C) Texas Parks and Wildlife
D) Environmental Protection Agency (EPA)
B) Texas Department of Agriculture (TDA)
Rationale: The TDA has primary authority over pesticide regulation and
licensing in the state of Texas.
A licensed applicator must notify the TDA of a change of address within how many
days?
A) 10 days
B) 30 days
C) 60 days
D) 90 days
B) 30 days
Rationale: TDA regulations require notification of any contact information
changes within a 30-day window.
How many years must a commercial or non-commercial applicator keep records of
pesticide applications?
A) 1 year
B) 2 years
, C) 5 years
D) Permanently
B) 2 years
Rationale: State law requires these records to be maintained and available for
inspection for at least two years.
What federal law governs the registration, sale, and use of pesticides in the United
States?
A) OSHA
B) FIFRA
C) RCRA
D) Clean Water Act
B) FIFRA
Rationale: The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) is
the primary federal pesticide law.
A "Restricted Use" pesticide (RUP) can be purchased by:
A) Anyone over the age of 21.
B) Only certified applicators or those under their direct supervision.
C) Any homeowner for residential use.
D) Only government employees.
B) Only certified applicators or those under their direct supervision
Rationale: RUPs are deemed to have a higher risk and require specialized
training to purchase and apply.
Safety & Human Health (16–25)
What is the most common route of pesticide exposure for applicators?
A) Oral (Ingestion)
B) Ocular (Eyes)
C) Dermal (Skin)
D) Inhalation (Breathing)
C) Dermal (Skin)
Rationale: Studies show that over 90% of all pesticide exposure during
application occurs through skin contact.
Which signal word on a label indicates the highest level of toxicity?
, A) CAUTION
B) WARNING
C) DANGER-POISON
D) ATTENTION
C) DANGER-POISON
Rationale: Danger-Poison (with skull and crossbones) indicates highly toxic
material; Caution indicates the lowest toxicity.
8. If a pesticide is spilled on your skin, what is the first step you should take?
A) Call emergency services.
B) Read the label.
C) Remove contaminated clothing and wash the area with soap and water.
D) Apply lotion to soothe the area.
C) Remove contaminated clothing and wash the area with soap and water
Rationale: Immediate decontamination is the priority to reduce absorption.
"LD50" refers to the amount of a chemical that kills what percentage of a test
population?
A) 10%
B) 50%
C) 100%
D) 0% (Safety level)
B) 50%
Rationale: LD50 stands for "Lethal Dose 50%." A lower LD50 number means
the chemical is more toxic.
What type of gloves should generally be worn when handling pesticides?
A) Leather
B) Cotton
C) Chemical-resistant (such as Nitrile or Neoprene)
D) Latexsurgical gloves
C) Chemical-resistant (such as Nitrile or Neoprene)
Rationale: Fabric and leather can absorb pesticides and hold them against
the skin; chemical-resistant materials provide a barrier.
, Environmental Concerns (11–25)
What is the term for the movement of pesticides through the air to non-target areas?
A) Leaching
B) Drift
C) Runoff
D) Volatilization
B) Drift
Rationale: Drift occurs during application when wind carries droplets or
particles away from the intended site.
"Leaching" refers to the movement of pesticides:
A) Across the surface of the ground.
B) Downward through the soil into groundwater.
C) Into the air as a gas.
D) Into the bodies of insects.
B) Downward through the soil into groundwater
Rationale: Pesticides with high solubility are at higher risk for leaching.
To prevent groundwater contamination, you should never mix or load pesticides:
A) Near a wellhead.
B) In the morning.
C) Without a hat.
D) Inside a vehicle.
A) Near a wellhead
Rationale: Mixing near wells provides a direct route for spills to enter the
groundwater.
Which weather condition is most likely to increase the risk of pesticide drift?
A) High humidity
B) High winds
C) Calm, overcast skies
D) Low temperatures
B) High winds
Rationale: Strong winds physically move the spray droplets away from the
target.
