  1. 1A pesticide container bears a printed panel, while a booklet is attached to the container. Which term includes both sources of use instructions?

    1. A. Label only
    2. B. Labeling
    3. C. Safety Data Sheet only
    4. D. Registration record

  6. 6A worn hose bursts during application and releases spray mix. Which preventive action most directly addresses this mishap?

    1. A. Inspect hoses and fittings before use
    2. B. Increase travel speed
    3. C. Use a smaller treated area
    4. D. Delay calibration until season end

    Answer: A

    Explanation: Preoperation inspection finds damaged hoses and fittings before pressure causes a release. The Vermont rule states: “Common types and causes of pesticide mishaps.”

    Reference: Vermont Pesticide Rule Adopted — Chapter 11, Application Equipment and Calibration, pp. 160-163

  7. 7A spray is directed in parallel strips over crop rows, leaving untreated space between strips. What application method is this?

    1. A. Band application
    2. B. Broadcast application
    3. C. Spot application
    4. D. Directed basal application

    Answer: A

    Explanation: Band application treats narrow parallel strips rather than the entire area. The Vermont rule states: “Methods used to apply various forms and formulations of pesticides.”

    Reference: Vermont Pesticide Rule Adopted — Chapter 11, Application Methods, pp. 157-158

  8. 8A Vermont farmer will apply a Class A pesticide on land the farmer rents to produce an agricultural commodity. Which certificate is required?

    1. A. Private applicator certificate
    2. B. Class B dealer license
    3. C. Pesticide company license
    4. D. Commercial applicator certificate

    Answer: A

    Explanation: Section 3.04(b) requires private certification for this Class A use on owned or rented production property. The Vermont rule states: “Understanding the meaning of product classification.”

    Reference: Vermont Pesticide Rule Adopted — Section 3.04(b), p. 9

  9. 9Which practice most directly reduces theft or intentional misuse of pesticides?

    1. A. Restrict keys and access to authorized people
    2. B. Install motion-activated exterior lighting
    3. C. Maintain a current pesticide inventory
    4. D. Train employees to report suspicious activity

    Answer: A

    Explanation: Access control is a core pesticide-site security measure. The Vermont rule states: “Maintaining chemical security for pesticides.”

    Reference: Vermont Pesticide Rule Adopted — Chapter 8, Pesticide Site Security, pp. 129-131

  10. 10A mixing pad drains toward a shallow well. Which change most directly reduces contamination risk?

    1. A. Move mixing and loading to a contained site away from the well
    2. B. Increase tank agitation beside the well
    3. C. Store empty containers at the wellhead
    4. D. Rinse spills into the drain

    Answer: A

    Explanation: Mixing and loading should be kept away from wells and vulnerable water sources. The Vermont rule states: “Drainage patterns.”

    Reference: Vermont Pesticide Rule Adopted — Chapter 7, Do Not Mix and Load Near Water, p. 115
