Illinois Aerial Application Ultimate Exam
**Question 1.** Which federal act defines “restricted-use pesticides” (RUPs) and
requires a certified applicator to handle them?
A) Clean Air Act
B) Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
C) Endangered Species Act
D) Resource Conservation and Recovery Act
Answer: B
Explanation: FIFRA classifies pesticides as either “general-use” or “restricted-use.”
Only certified applicators may purchase or apply RUPs.
**Question 2.** Under the Illinois Pesticide Act, which document must a pilot
retain for at least three years after an aerial application?
A) Flight plan log
B) Pesticide use record (Form 5)
C) Weather briefing printout
D) Aircraft maintenance log
Answer: B
Explanation: Illinois law requires a complete pesticide use record, including
product, rate, and location, to be kept for a minimum of three years.
**Question 3.** Part 137 of the Federal Aviation Regulations primarily addresses
which of the following?
A) Air traffic control communications
B) Agricultural aircraft operations and safety standards
C) Commercial passenger airline certification
D) Unmanned aircraft system (UAS) rules
,Illinois Aerial Application Ultimate Exam
Answer: B
Explanation: FAR Part 137 sets operational, maintenance, and crew requirements
for aircraft used in agricultural spraying.
**Question 4.** The Worker Protection Standard (WPS) mandates a minimum
re-entry interval of how many hours after an aerial application of a pesticide
labeled “restricted-use”?
A) 2 hours
B) 4 hours
C) 6 hours
D) 8 hours
Answer: C
Explanation: For restricted-use pesticides, the EPA requires a minimum of six
hours before workers may re-enter the treated area without additional
protection.
**Question 5.** Which route of exposure is most likely when a pilot fails to wear
a properly fitted respirator while loading a high-volatility organophosphate?
A) Dermal
B) Inhalation
C) Oral
D) Ocular
Answer: B
Explanation: Inhalation is the primary route for volatile chemicals; a respirator
prevents aerosolized organophosphate particles from being breathed in.

**Question 6.** Acute toxicity of a pesticide is best described as:
A) Effects that appear after repeated low-dose exposure over months
B) Immediate or short-term health effects following a single exposure
C) Chronic organ damage that develops years later
D) Toxicity only to non-target organisms
Answer: B
Explanation: Acute toxicity refers to health effects that occur shortly after a single
or short-term exposure.
**Question 7.** Which piece of personal protective equipment (PPE) is required
for a loader handling a liquid pesticide concentrate in an enclosed “nurse” truck?
A) Steel-toe boots only
B) Full-body chemical suit, gloves, and splash goggles
C) Hearing protection only
D) High-visibility vest only
Answer: B
Explanation: Loaders must wear a complete chemical suit, chemical-resistant
gloves, and splash-proof goggles when handling concentrated liquids in confined
spaces.
**Question 8.** Early symptoms of organophosphate poisoning include all
EXCEPT:
A) Excessive salivation
B) Muscle twitching
C) Skin flushing
D) Miosis (pinpoint pupils)
, Illinois Aerial Application Ultimate Exam
Answer: C
Explanation: Skin flushing is not a typical early sign of organophosphate
poisoning; the other symptoms result from acetylcholinesterase inhibition.
**Question 9.** When mixing a pesticide, the “order of addition” rule states that
you should add:
A) Water first, then concentrate, then adjuvant
B) Concentrate first, then water, then adjuvant
C) Adjuvant first, then water, then concentrate
D) Water, then adjuvant, then concentrate
Answer: A
Explanation: Adding water first prevents the concentrate from forming a “hot
spot” that could cause splashing or excessive heat.
**Question 10.** Vapor drift is most likely to occur under which condition?
A) Low temperature, high humidity, and low wind
B) High temperature, low humidity, and high volatility pesticide
C) Heavy rain during application
D) High droplet size (VMD > 500 µm)
Answer: B
Explanation: High temperature and low humidity increase volatility, causing
chemicals to evaporate and drift as vapor.
**Question 11.** Which meteorological phenomenon creates a “temperature
inversion” that can trap pesticide droplets near the ground?
A) Warm front passing overhead
**Question 1.** Which federal act defines “restricted-use pesticides” (RUPs) and
requires a certified applicator to handle them?
A) Clean Air Act
