Question 1
Which of the following correctly describes an arthropod?
A. Arthropods have an internal skeleton and a backbone.
B. Arthropods have an exoskeleton and jointed limbs.
C. Arthropods are warm-blooded, whereas vertebrates are cold-blooded.
D. Arthropods reproduce exclusively through live birth.
Correct Answer: B. Arthropods have an exoskeleton and jointed
limbs. Arthropods are characterized by segmented bodies, jointed appendages,
and an external skeleton (exoskeleton). They lack backbones, distinguishing them
from vertebrates. Body temperature and reproductive strategies vary greatly
across both groups, making the other options incorrect .
Question 2
What is the primary purpose of the pesticide label?
A. To advertise the product's features and benefits.
B. To provide legally enforceable directions for safe and effective use.
C. To list all competing products on the market.
D. To estimate crop yield expectations.
,Correct Answer: B. To provide legally enforceable directions for safe and
effective use. The pesticide label is a legal document approved by the EPA under
FIFRA. It provides mandatory instructions for handling, application, storage,
disposal, and safety precautions. Approved labels have the force of law .
Question 3
Which signal word indicates the highest level of acute toxicity?
A. Warning
B. Caution
C. Notice
D. Danger
Correct Answer: D. Danger. "Danger" indicates the highest level of acute toxicity
among pesticide signal words. It may also accompany the skull-and-crossbones
symbol for highly toxic products. "Warning" indicates moderate toxicity, and
"Caution" indicates low toxicity .
Question 4
Which federal agency is responsible for registering pesticides in the United States?
A. USDA (United States Department of Agriculture)
B. FDA (Food and Drug Administration)
C. OSHA (Occupational Safety and Health Administration)
D. Environmental Protection Agency (EPA)
Correct Answer: D. Environmental Protection Agency (EPA). The EPA evaluates
pesticide safety and effectiveness before products are registered for sale and use
under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) .
Question 5
,Which route of pesticide exposure is responsible for the majority of occupational
poisonings?
A. Inhalation
B. Oral (ingestion)
C. Dermal (skin contact)
D. Ocular (eye contact)
Correct Answer: C. Dermal (skin contact). Dermal absorption is the most common
route of occupational pesticide exposure. Applicators frequently contact pesticides
during mixing, loading, and application. Proper personal protective equipment
(PPE), especially chemical-resistant gloves, is essential to prevent dermal
exposure .
Question 6
What does the acronym PPE stand for in pesticide safety?
A. Personal Pest Equipment
B. Public Protection Equipment
C. Professional Pesticide Equipment
D. Personal Protective Equipment
Correct Answer: D. Personal Protective Equipment. PPE includes clothing and
equipment worn to reduce pesticide exposure, such as chemical-resistant gloves,
goggles, respirators, coveralls, and boots. The pesticide label specifies the
minimum PPE required for handling and applying the product .
Question 7
Which factor most significantly influences pesticide spray drift?
A. Soil color
B. Air temperature only
, C. Crop height
D. Wind speed
Correct Answer: D. Wind speed. Higher wind speeds greatly increase the
likelihood of pesticide drift onto non-target areas. Applicators must monitor wind
conditions and avoid applications during high winds. Drift can be minimized
through proper nozzle selection, lower pressures, and favorable weather
conditions .
Question 8
The term "LD50" is a measure of:
A. Application rate
B. Shelf life
C. Solubility
D. Acute toxicity
Correct Answer: D. Acute toxicity. LD50 (Lethal Dose 50%) represents the dose
required to kill 50% of a test population and is an indicator of acute toxicity. The
lower the LD50, the more toxic the pesticide. This value helps determine the signal
word on the label .
Question 9
What should be done with empty pesticide containers?
A. Burn them
B. Throw them into a ditch
C. Reuse them for water storage
D. Dispose of them according to label directions
Correct Answer: D. Dispose of them according to label directions. Labels provide
specific disposal requirements that help prevent environmental contamination and
