Question 1
The term "LC50" on a pesticide label refers to:
A. The lethal concentration that kills 50% of test organisms in a water-based
environment
B. The lethal concentration that kills 50% of test organisms through inhalation
exposure
C. The lethal dose that kills 50% of test organisms through dermal exposure
D. The lethal concentration that kills 50% of test organisms through oral
ingestion
Answer: B. The lethal concentration that kills 50% of test organisms through
inhalation exposure
Rationale: LC50 stands for Lethal Concentration 50, which measures the
concentration of a pesticide in air that kills 50% of test subjects through
inhalation exposure. This is distinguished from LD50, which measures lethal
dose through oral or dermal routes.
Question 2
Which signal word appears on a label with a skull and crossbones symbol?
A. DANGER—POISON
B. DANGER
C. WARNING
D. CAUTION
Answer: A. DANGER—POISON
Rationale: The skull and crossbones symbol indicates the highest toxicity
category and is accompanied by the signal word DANGER—POISON. This
,signal word is reserved for pesticides that are highly toxic by oral, dermal, or
inhalation routes.
Question 3
What is the primary purpose of pesticide labeling?
A. To advertise the product
B. To provide legal instructions for safe use
C. To increase product sales
D. To list alternative pesticides
Answer: B. To provide legal instructions for safe use
Rationale: The pesticide label is a legal document that provides directions
for safe, effective, and lawful use of the pesticide. It has the force of law under
federal and state regulations.
Question 4
The name "Roundup Pro Max 50.2SL" on a pesticide label indicates:
A. The brand name and 50.2 percent active ingredients, formulated as a
soluble liquid
B. The chemical name and 50.2 percent inert ingredients, formulated as a
soluble liquid
C. The brand name and 50.2 percent inert ingredients, formulated as a soluble
liquid
D. The chemical name and 50.2 percent active ingredients, formulated as a
soluble liquid
Answer: A. The brand name and 50.2 percent active ingredients, formulated
as a soluble liquid
Rationale: In pesticide labeling, the name includes the brand
name ("Roundup Pro Max"), the percentage of active ingredients (50.2%),
and the formulation type (SL = Soluble Liquid). The percentage refers to
active ingredients, not inert ingredients.
,Question 5
A pesticide label with the signal word "CAUTION" indicates:
A. The pesticide is highly toxic and requires a skull and crossbones symbol
B. The pesticide has the lowest level of acute toxicity
C. The pesticide is moderately toxic
D. The pesticide is not regulated by federal law
Answer: B. The pesticide has the lowest level of acute toxicity
Rationale: "CAUTION" is the signal word for the lowest toxicity category.
Pesticides with this signal word have LD50 values greater than 500 mg/kg for
oral exposure and are considered slightly toxic.
Question 6
What does the abbreviation "WP" stand for in pesticide formulation?
A. Water Permeable
B. Wettable Powder
C. Water Protection
D. Weight Percentage
Answer: B. Wettable Powder
Rationale: WP stands for Wettable Powder, which is a dry, finely ground
formulation that mixes with water to form a suspension. Wettable powders
require agitation in the spray tank to remain suspended.
Question 7
The "Restricted Use Pesticide" designation on a label means:
A. The pesticide can only be used on certain crops
B. The pesticide can only be purchased and used by certified applicators
C. The pesticide is only available in certain states
D. The pesticide can only be used during certain seasons
, Answer: B. The pesticide can only be purchased and used by certified
applicators
Rationale: Restricted Use Pesticides (RUPs) can only be applied by certified
applicators or persons under their direct supervision. This designation
indicates the pesticide may cause unreasonable adverse effects to the
environment or human health if not applied by trained professionals.
Question 8
What information is found in the "Directions for Use" section of a pesticide
label?
A. Only the chemical composition of the pesticide
B. Sites where the pesticide can be applied, target pests, application rates, and
timing
C. Only the manufacturer's contact information
D. Only safety precautions and first aid instructions
Answer: B. Sites where the pesticide can be applied, target pests, application
rates, and timing
Rationale: The "Directions for Use" section provides specific instructions
on where, when, how, and at what rate the pesticide should be applied.
Using a pesticide in a manner inconsistent with the label directions is a
violation of federal law.
Question 9
Which statement about the "Environmental Hazards" section of a pesticide
label is TRUE?
A. It only applies to aquatic environments
B. It provides information about risks to wildlife, water sources, and non-
target organisms
C. It is optional for all pesticide labels
D. It only applies to pesticides used in agricultural settings
