LAWS AND REGULATIONS (Questions 1-10)
Q1: Under the Illinois Pesticide Act (415 ILCS 60/), how long must commercial applicators maintain
records of pesticide applications?
A. 1 year from the date of application
B. 2 years from the date of application [CORRECT]
C. 3 years from the date of application
D. 5 years from the date of application
Correct Answer: B
Rationale: The Illinois Pesticide Act mandates that all commercial applicators maintain complete
application records for a minimum of 2 years, including product name, EPA registration number, amount
applied, location, date, and applicator identification.
Q2: Under FIFRA Section 12(a)(2)(G), what is the penalty for applying a pesticide in a manner
inconsistent with its labeling?
A. A written warning for first-time violations
B. Civil penalties up to $50,000 per violation [CORRECT]
C. Mandatory suspension of applicator license for 30 days
D. No penalty if no environmental damage occurs
Correct Answer: B
Rationale: FIFRA establishes that applying pesticides in a manner inconsistent with labeling directions
constitutes a violation subject to civil penalties of up to $50,000 per violation, emphasizing the legal
weight of the label as the law.
,Q3: The Worker Protection Standard (WPS) requires employers to provide decontamination supplies for
how many days after the Restricted Entry Interval (REI) expires?
A. 3 days
B. 7 days
C. 30 days [CORRECT]
D. Until the next pesticide application
Correct Answer: C
Rationale: WPS regulations require employers to maintain decontamination supplies (water, soap,
single-use towels) at the worksite for 30 days after the REI expires, ensuring workers have access to
cleanup materials during the post-application period.
Q4: What is the minimum Pre-Harvest Interval (PHI) that must be observed for most foliar insecticides
applied to soybeans in Illinois?
A. 7 days
B. 14 days
C. 18-45 days depending on the product [CORRECT]
D. 60 days
Correct Answer: C
Rationale: PHI requirements vary significantly by active ingredient and crop; soybean foliar insecticides
typically range from 18-45 days, and applicators must consult the specific product label for the exact
interval before harvest.
Q5: Under Illinois-specific groundwater protection regulations, what is the required setback distance for
mixing/loading pesticides from water wells?
A. 25 feet
B. 50 feet [CORRECT]
C. 100 feet
D. 200 feet
Correct Answer: B
Rationale: Illinois regulations require a minimum 50-foot setback between pesticide mixing/loading
operations and water wells to prevent direct contamination of groundwater sources through spills or
back-siphoning.
,Q6: Which federal act requires applicators to protect endangered species by checking the EPA
Endangered Species Protection Bulletin before applying pesticides in designated counties?
A. Clean Water Act
B. Endangered Species Act [CORRECT]
C. Federal Insecticide, Fungicide, and Rodenticide Act
D. National Environmental Policy Act
Correct Answer: B
Rationale: The Endangered Species Act mandates protection measures for listed species, and EPA
implements this through county-specific bulletins that applicators must consult to identify required
buffer zones or application restrictions.
Q7: Under Illinois WPS requirements, what is the minimum age for workers to enter treated areas
during an REI?
A. 16 years old
B. 18 years old [CORRECT]
C. 21 years old
D. No minimum age if properly trained
Correct Answer: B
Rationale: The revised WPS (2015) establishes 18 years as the minimum age for early-entry workers,
prohibiting anyone under 18 from entering treated areas during the REI, even with appropriate PPE.
Q8: How soon must a commercial applicator in Illinois report a pesticide spill that enters or may enter
surface water?
A. Within 24 hours
B. Immediately, but no later than the end of the business day
C. Within 4 hours if > reportable quantity [CORRECT]
D. Only if fish kills are observed
Correct Answer: C
Rationale: Illinois requires immediate reporting of pesticide spills that reach or threaten surface water
when quantities exceed reportable thresholds, with notification to the Illinois Emergency Management
Agency and IDOA within 4 hours.
Q9: What information is NOT required on Illinois pesticide application records under 415 ILCS 60/?
, A. Wind speed and direction at time of application
B. Brand name and EPA registration number of pesticide
C. Social Security number of the property owner [CORRECT]
D. Total amount of pesticide applied
Correct Answer: C
Rationale: Illinois recordkeeping requirements specify product identification, application amounts,
locations, dates, and applicator details, but do not require personal identification numbers such as Social
Security numbers of property owners.
Q10: Under FIFRA, which statement accurately describes the relationship between state and federal
pesticide regulations?
A. State regulations can be less stringent but never more stringent than federal standards
B. States may establish more stringent regulations than federal standards [CORRECT]
C. Federal regulations automatically preempt all state pesticide laws
D. States cannot regulate pesticides registered by EPA
Correct Answer: B
Rationale: FIFRA explicitly preserves state authority to regulate pesticides more stringently than federal
standards, allowing Illinois to implement additional requirements such as stricter buffer zones or
additional training mandates.
INTEGRATED PEST MANAGEMENT (Questions 11-25)
Q11: What is the established economic threshold for soybean aphid (Aphis glycines) treatment in Illinois
field crops?
A. 50 aphids per plant
B. 100 aphids per plant
C. 250 aphids per plant [CORRECT]
D. 500 aphids per plant
Correct Answer: C
Rationale: University of Illinois Extension research establishes 250 aphids per plant as the economic
threshold for soybean aphid treatment, representing the population density where yield loss exceeds
treatment costs.
Q12: Which Bt trait technology targets both corn rootworm (Diabrotica spp.) and European corn borer
(Ostrinia nubilalis)?
