1What is the most important source of information about how to safely and legally use a pesticide?

A.The manufacturer's website

B.The pesticide product label

C.Advice from other applicators

D.The material safety data sheet

Explanation: The pesticide product label is a legal document and the single most important source of information about safe and legal pesticide use. It is a violation of federal law to use any pesticide in a manner inconsistent with its labeling. The label contains critical information about application rates, safety precautions, environmental hazards, and first aid instructions.

2What does the signal word "DANGER" on a pesticide label indicate?

A.The product is slightly toxic

B.The product is moderately toxic

C.The product is highly toxic and may be fatal if swallowed, inhaled, or absorbed through the skin

D.The product is a restricted use pesticide

Explanation: The signal word "DANGER" indicates the highest level of acute toxicity. Products with this signal word may be fatal or cause irreversible eye or skin damage. DANGER is associated with Toxicity Category I, the most hazardous category. Some DANGER labels also include the word "POISON" with a skull and crossbones symbol for the most acutely toxic products.

3What does the signal word "WARNING" on a pesticide label indicate?

A.The product is highly toxic (Category I)

B.The product is moderately toxic (Category II)

C.The product is slightly toxic (Category III)

D.The product is practically nontoxic (Category IV)

Explanation: The signal word "WARNING" indicates the product is moderately toxic, classified as Toxicity Category II. Products bearing this signal word can cause moderate illness or injury through oral, dermal, or inhalation exposure. Users should follow all safety precautions and PPE requirements listed on the label.

4What does the signal word "CAUTION" on a pesticide label indicate?

A.The product is highly toxic

B.The product is moderately toxic

C.The product is slightly toxic to relatively nontoxic (Category III or IV)

D.The product has been recalled

Explanation: The signal word "CAUTION" indicates the product is slightly toxic to relatively nontoxic, classified as Toxicity Category III or IV. While these products present the lowest acute toxicity risk, applicators should still follow all label directions, wear recommended PPE, and avoid unnecessary exposure.

5What is the EPA registration number on a pesticide label used for?

A.To track the price of the product

B.To identify the specific product and its manufacturer as registered with the EPA

C.To indicate the product's expiration date

D.To show which state approved the product

Explanation: The EPA registration number uniquely identifies each pesticide product and its registrant (manufacturer). It is assigned when the EPA approves the product for sale and use. The registration number is formatted as a two- or three-part number (e.g., 524-445-AA) where the first number identifies the company, the second identifies the product, and the optional third identifies a supplemental distributor.

6What is the "active ingredient" listed on a pesticide label?

A.The water or solvent that carries the pesticide

B.The chemical component that actually controls the target pest

C.Any ingredient that is not inert

D.The fragrance added to the product

Explanation: The active ingredient is the chemical component in a pesticide formulation that actually prevents, destroys, repels, or mitigates the target pest. Federal law requires that active ingredients be listed by name and percentage on the label. The remaining portion consists of inert (other) ingredients, which serve as carriers, solvents, or adjuvants.

7What does the "Precautionary Statements" section of a pesticide label include?

A.Only the signal word

B.Hazards to humans and domestic animals, environmental hazards, and physical/chemical hazards

C.Only first aid information

D.Only storage and disposal information

Explanation: The Precautionary Statements section contains three subsections: (1) Hazards to Humans and Domestic Animals — routes of exposure, specific organ effects, and required PPE; (2) Environmental Hazards — risks to fish, birds, bees, and groundwater; and (3) Physical or Chemical Hazards — flammability, explosiveness, or chemical reactivity. This section helps applicators avoid harm during use.

8What information is found in the "Directions for Use" section of a pesticide label?

A.Only the mixing ratio

B.The target pests, application sites, rates, timing, methods, restricted entry intervals, pre-harvest intervals, and application restrictions

C.Only environmental precautions

D.Only the crops the product can be used on

Explanation: The Directions for Use section is one of the most detailed parts of the label. It specifies the pests controlled, sites where the product can be used, application rates, timing, methods, equipment requirements, restricted entry intervals (REIs), pre-harvest intervals (PHIs), maximum number of applications, and any geographic or seasonal restrictions.

9What does "Restricted Use Pesticide" (RUP) at the top of a label mean?

A.The product can only be purchased in certain states

B.The product is restricted to use by or under the direct supervision of a certified applicator due to its potential to cause unreasonable adverse effects

C.The product has been partially banned by the EPA

D.The product can only be applied during certain months

Explanation: A Restricted Use Pesticide (RUP) designation means the EPA has determined the product may cause unreasonable adverse effects to the environment or injury to applicators, even when used as directed. RUPs can only be sold to and used by certified applicators or persons under their direct supervision. This classification is based on factors such as acute toxicity, effects on wildlife, or groundwater contamination potential.

10What is the "pre-harvest interval" (PHI) on a pesticide label?

A.The time between planting and the first application

B.The minimum number of days that must pass between the last pesticide application and crop harvest

C.The time between two consecutive applications

D.The time before the pesticide expires on the shelf

Explanation: The pre-harvest interval (PHI) is the minimum number of days that must pass between the last application of a pesticide and the harvest of the treated crop. This interval allows time for the pesticide residue to degrade to levels that are safe for consumption, as established by EPA tolerances. Violating the PHI can result in illegal residues on food.
