  1. 1A pesticide handler needs the number showing that EPA approved a specific product label. Which label identifier should the handler use?

    1. A. EPA registration number
    2. B. EPA establishment number
    3. C. special local need number
    4. D. net contents statement

    Answer: A

    Explanation: The guide states, "An EPA registration number (for example. EPA Reg. No. 3120-28O-AA) indicates that the pesticide label has been approved by EPA." Therefore the registration number, not the establishment number, is the approval identifier.

    Reference: Apc Unit 2 — Registration and establishment numbers

  2. 2Assuming comparable scales for toxicity and exposure, which handling situation creates the greatest pesticide hazard?

    1. A. High toxicity with high exposure
    2. B. High toxicity with low exposure
    3. C. Low toxicity with high exposure
    4. D. Low toxicity with low exposure

    Answer: A

    Explanation: The safety unit gives the equation "Hazard = Toxicity x Exposure." With both factors high, their combined hazard is greater than in the other listed combinations.

    Reference: Apc Unit 6 — Harmful Effects and Emergency Response—Hazard

  3. 3After irrigation, pesticide moves downward through soil toward groundwater. What type of movement is this?

    1. A. Leaching
    2. B. Runoff
    3. C. Drift
    4. D. Volatilization

    Answer: A

    Explanation: The guide states, "Most pesticide movement in water is across the treated surface (runoff) or downward from the surface (leaching)." Downward movement toward groundwater is therefore leaching.

    Reference: Apc Unit 4 — Pesticide Movement—Water

  4. 4Crop damage appears, but the causal organism has not been identified. What is the first step in developing a sound pest-control strategy?

    1. A. Identify the pest
    2. B. Select an application rate
    3. C. Calibrate the sprayer
    4. D. Choose a residual formulation

    Answer: A

    Explanation: The guide states, "Accurate identification is the first step in an effective pest management program." Because the causal organism is unknown, identification must precede rate, equipment, or formulation choices.

    Reference: Apc Unit 1 — Principles of Pest Control—Identification

  5. 5Repeated use of one pesticide type is selecting for resistant pests. Which change best slows further resistance development?

    1. A. Rotate pesticide types and use an IPM program
    2. B. Rotate brand names while retaining the same active ingredient
    3. C. Alternate formulations while retaining the same pesticide type
    4. D. Continue the same pesticide type at its highest labeled rate

    Answer: A

    Explanation: The guide states, "Pest resistance can be reduced by using integrated pest management and rotating the types of pesticides used." Changing only brand or formulation does not accomplish that rotation.

    Reference: Apc Unit 1 — Avoiding Pest Resistance—Test Your Knowledge

  6. 6Which pressure-and-nozzle combination generally produces droplets with the lowest off-target drift potential?

    1. A. Lower pressure with a coarse nozzle
    2. B. Lower pressure with a fine nozzle
    3. C. Higher pressure with a coarse nozzle
    4. D. Higher pressure with a fine nozzle

    Answer: A

    Explanation: The guide states, "Lower pressure and coarse nozzles produce larger droplets with less drift potential." Option A combines both drift-reducing settings.

    Reference: Apc Unit 4 — Pesticide Movement—Particles and droplets

  7. 7Which activity falls within Hawaiʻi private applicator certification?

    1. A. Using a restricted-use pesticide to produce crops on land rented by the applicator
    2. B. Applying a restricted-use pesticide for a fee on a neighbor's resort grounds
    3. C. Treating public highway rights-of-way under a service contract
    4. D. Providing structural pest control for compensation

    Answer: A

    Explanation: HAR §4-66-2 states that a private applicator uses restricted-use pesticide "for purposes of producing any agricultural commodity on property owned or rented by the applicator or the applicator's employer." Treating crops on rented land fits that definition.

    Reference: HAR 4 66 2019 Pesticides — HAR §4-66-2, definition of private pesticide applicator, pp. 66-8 to 66-9

  8. 8Before assigning a non-certified worker to use a restricted-use pesticide, what certification-related condition must the supervisor satisfy?

    1. A. The supervisor's certification category must cover that use
    2. B. The non-certified worker's training category must cover that use
    3. C. The pesticide dealer's permit category must cover that use
    4. D. A certification category held in another state must cover that use

    Answer: A

    Explanation: HAR §4-66-61(1) requires supervision by "an applicator certified in each category applicable to the restricted use pesticide being used." The covering category must therefore belong to the supervising certified applicator.

    Reference: HAR 4 66 2019 Pesticides — HAR §4-66-61(1), p. 66-67

  9. 9Which combination provides the basic access control for any pesticide storage site, from a cabinet to a building?

    1. A. A secure lock plus pesticide warning signs
    2. B. A perimeter fence without a locked storage enclosure
    3. C. An inventory list without access restriction
    4. D. Exterior lighting without a lock or warning sign

    Answer: A

    Explanation: The guide states, "Whether the storage site is as small as a cabinet or closet or as large as an entire room or building, keep it securely locked." It also requires posted pesticide warnings, so option A supplies both basic controls.

    Reference: Apc Unit 11 — Pesticide Storage—Secure the site

  10. 10A grower aims to reduce a pest population until crop damage is acceptable, without eliminating every pest. Which control objective is this?

    1. A. Suppression
    2. B. Prevention
    3. C. Eradication
    4. D. Exclusion

    Answer: A

    Explanation: The guide defines "suppression" as "reducing pest numbers or damage to an acceptable level." That matches the grower's objective without requiring elimination of every pest.

    Reference: Apc Unit 1 — Pest Control Goals
