C.Indiana Department of Health

D.U.S. Fish and Wildlife Service

Explanation: The Office of Indiana State Chemist (OISC) administers the pesticide applicator certification and licensing program in Indiana, enforcing both state and federal pesticide laws.

2What minimum passing score is required on Indiana's pesticide applicator certification exams?

A.60%

B.65%

C.70%

D.80%

Explanation: Indiana requires a minimum passing score of 70% on pesticide applicator certification exams. Both the core/general standards exam and category-specific exams must meet this threshold.

3What is the fee structure for Indiana's commercial pesticide applicator certification?

A.Free of charge

B.$50 exam + $25/category + $100 annual business license

C.$500 flat fee

D.$1,000 annual fee

Explanation: The fee for Indiana's commercial pesticide applicator certification is $50 exam + $25/category + $100 annual business license. Fee structures vary by state, so applicators should verify current fees with Office of Indiana State Chemist (OISC).

4Under FIFRA, what is a restricted-use pesticide (RUP)?

A.Any organic pesticide

B.A pesticide classified by EPA as requiring certification due to potential harm to applicators or environment

C.A pesticide that has been recalled

D.Any pesticide used in agriculture

Explanation: Under FIFRA, a restricted-use pesticide (RUP) has been classified by EPA as potentially harmful to applicators or the environment even when used as directed. RUPs may only be purchased and applied by or under the direct supervision of a certified applicator.

5What does the signal word 'DANGER' on a pesticide label indicate?

A.The product is slightly toxic

B.The product has the highest toxicity level (Category I)

C.The product is expired

D.The product is moderately toxic

Explanation: DANGER (or DANGER/POISON with skull and crossbones) indicates the highest toxicity category (Category I). These products can cause severe eye or skin injury or are highly toxic if swallowed, inhaled, or absorbed through the skin.

6What is the most common route of occupational pesticide exposure for applicators?

A.Oral ingestion

B.Inhalation

C.Dermal (skin) absorption

D.Eye contact

Explanation: Dermal (skin) absorption accounts for approximately 97% of occupational pesticide exposures. This is why wearing chemical-resistant gloves and protective clothing during mixing, loading, and application is critical.

7What is the primary purpose of Integrated Pest Management (IPM)?

A.To maximize pesticide sales

B.To combine biological, cultural, physical, and chemical methods for effective pest management with minimal environmental impact

C.To eliminate all insect species

D.To reduce labor costs only

Explanation: IPM uses a combination of pest management strategies to control pests effectively while minimizing risks to human health, beneficial organisms, and the environment. Chemical control is used only when other methods are insufficient and pest populations reach economic thresholds.

8What type of gloves should NEVER be used when handling pesticides?

A.Chemical-resistant nitrile gloves

B.Chemical-resistant neoprene gloves

C.Leather or cotton-lined gloves

D.Butyl rubber gloves

Explanation: Leather and cotton gloves should never be worn when handling pesticides because they absorb pesticides and cannot be properly decontaminated. Once contaminated, they become a continuous source of dermal exposure. Always use chemical-resistant gloves as specified on the label.

9What does LD50 measure?

A.The lethal concentration in air

B.The dose required to kill 50% of a test animal population, expressed in mg/kg body weight

C.The time until death

D.The minimum effective dose

Explanation: LD50 (Lethal Dose 50) measures the dose of a substance that kills 50% of a test animal population, expressed in milligrams per kilogram of body weight. A lower LD50 value indicates greater toxicity. LD50 values are used to determine toxicity categories and signal words.

10Which pesticide formulation type consists of dry particles applied directly without mixing with water?

A.Emulsifiable concentrate (EC)

B.Wettable powder (WP)

C.Granular (G)

D.Solution (S)

Explanation: Granular (G) formulations are ready-to-use dry particles that are applied directly to the target area without mixing with water. They produce no drift risk, require no special mixing equipment, and reduce applicator exposure. They are applied using spreaders or by hand.
