ANSWERS LATEST UPDATE THIS YEAR
QAC Category B - Landscape Maintenance certification. It focuses on the integrated
management of pests in ornamental and turf settings, emphasizing safety, environmental
stewardship, and legal compliance.
QAC Category B: Exam Content Overview
The following areas are comprehensively covered in this practice material:
• Pest Identification: Recognizing insects, diseases, weeds, and vertebrate pests in
California landscapes.
• Pesticide Laws and Regulations: DPR requirements, licensing, record-keeping, and
signage.
• Integrated Pest Management (IPM): Cultural, biological, and chemical control
strategies.
• Application Equipment & Calibration: Calculations for sprayers, spreaders, and nozzles.
• Pesticide Safety: PPE requirements, signal words, toxicity, and first aid.
• Environmental Protection: Preventing runoff, protecting pollinators, and groundwater
safety.
QAC Category B Practice Exam: Batch 1
(Sample of the 100-question comprehensive set)
1. Which of the following is a selective herbicide that controls broadleaf weeds but not
grasses?
1
, Page 2 of 87
A. Glyphosate
B. 2,4-D
C. Paraquat
D. Diquat
Answer: B.
Rationale: 2,4-D is a synthetic auxin that disrupts growth in dicots (broadleaf plants) while
monocots (grasses) are generally able to metabolize it or avoid absorption, making it a staple
for turf maintenance.
2. What is the most important factor influencing the effectiveness of a pesticide application?
A. Weather
B. Proper timing
C. Pest color
D. Wind direction
Answer: B.
Rationale: While all factors matter, applying a pesticide during the most vulnerable life stage of
the pest (timing) ensures the highest mortality rate and prevents unnecessary re-application.

3. According to California law, how long must a landscape maintenance business keep records
of pesticide applications?
A. 1 year
B. 2 years
C. 3 years
D. 5 years
Answer: B.
Rationale: The Department of Pesticide Regulation (DPR) requires that all professional pesticide
application records be maintained for at least 2 years for inspection purposes.
4. When calibrating a backpack sprayer, you find that it delivers 1 gallon over 200 square feet.
How many gallons will be needed to treat a 1,000 square foot planter bed?
A. 2 gallons
B. 4 gallons
C. 5 gallons
D. 10 gallons
Answer: C.
3
, Page 4 of 87
Rationale: Using the ratio $1/200 = x/1000$, we find $200x = 1000$, so $x = 5$. Calibration
ensures the legal rate on the label is not exceeded.
5. Which signal word on a pesticide label indicates the highest level of acute toxicity?
A. CAUTION
B. WARNING
C. DANGER
D. NOTICE
Answer: C.
Rationale: "DANGER" (often accompanied by "POISON" and a skull and crossbones) represents
the highest toxicity category. "WARNING" is moderate, and "CAUTION" is the lowest.
6. "Drift" is most likely to occur under which of the following conditions?
A. High humidity and no wind
B. High temperatures and high wind speeds
C. Low temperatures and overcast skies
D. Early morning with heavy dew
Answer: B.
