  1. 1A Nevada farmer wants to apply a restricted-use pesticide while producing an agricultural commodity. Which location fits the statutory scope of a private applicator?

    1. A. A field the farmer rents for crop production
    2. B. A neighbor's field treated for a fixed cash fee
    3. C. A cooperative field treated for a percentage fee
    4. D. A processor's field treated under a service contract

    Answer: A

    Explanation: The statute says "property owned or rented by the applicator"; the farmer's own or rented production property therefore fits Nevada's private-applicator scope.

    Reference: NRS: CHAPTER 555 - CONTROL OF INSECTS, PESTS AND NOXIOUS WEEDS — NRS 555.2681

  2. 2After a Nevada private applicator treats a field with a restricted-use pesticide, how long must the application record be retained?

    1. A. 1 year
    2. B. 2 years
    3. C. 3 years
    4. D. 4 years

    Answer: B

    Explanation: NAC 555.700 requires the treatment record to be kept "for 2 years"; that makes two years the required retention period.

    Reference: NAC: CHAPTER 555 - CONTROL OF INSECTS, PESTS AND NOXIOUS WEEDS — NAC 555.700 — Application of restricted-use pesticides by private applicators; subsection 1

  3. 3A pesticide readily dissolves in irrigation water and moves with it. Which chemical characteristic is most directly involved?

    1. A. Adsorption
    2. B. Persistence
    3. C. Solubility
    4. D. Volatility

    Answer: C

    Explanation: The manual states, "Solubility is a measure of the ability of a pesticide to dissolve in a solvent"; the product's movement with irrigation water therefore reflects solubility.

    Reference: General Knowledge: Pesticide Use and the Environment — p. 2

  4. 4A farm combines prevention, cultural practices, traps, beneficial organisms and carefully timed pesticides. Which management strategy is this?

    1. A. Integrated pest management
    2. B. Organic production
    3. C. Biological control
    4. D. Pesticide rotation

    Answer: A

    Explanation: The manual defines IPM as a strategy that "uses a combination of tactics to reduce pests to tolerable levels"; the farm's combined tactics are integrated pest management.

    Reference: Ch 04 Ipm — p. 1

  5. 5At the start of a plant disease cycle, an overwintering biotic agent causes the first infection. What is that starting material called?

    1. A. Secondary inoculum
    2. B. Primary inoculum
    3. C. Infection court
    4. D. Disease cycle

    Answer: B

    Explanation: The manual calls the overwintering stage that begins initial infection "primary inoculum"; that is the starting material in this disease cycle.

    Reference: General Knowledge: General Pest Problems — p. 7

  6. 6Monitoring confirms an economically damaging alfalfa weevil population. Which life stage is the current chemical-control target?

    1. A. Egg
    2. B. Adult
    3. C. Larva
    4. D. Pupa

    Answer: C

    Explanation: Because former adult controls were canceled, the manual directs, "Therefore, treat only for larvae"; larvae are the current chemical-treatment target.

    Reference: Category A: Agricultural Plant Pest Control — pp. 5-6

  7. 7A livestock parasite spends its life inside the animal's gut, heart or lungs. Which category describes it?

    1. A. Ectoparasite
    2. B. Endoparasite
    3. C. Parasitoid
    4. D. Pathogen

    Answer: B

    Explanation: The manual says endoparasites "spend their lives inside the animal’s organs or organ systems"; a gut, heart or lung parasite is an endoparasite.

    Reference: Category B: Agricultural Animal Pest Control — p. 4

  8. 8A Nevada private applicator accidentally spills 2 gallons of unmixed pesticide at an operating site. By when must the applicator telephone the Director or designee?

    1. A. Within 12 hours
    2. B. Within 48 hours
    3. C. Within 24 hours
    4. D. Within 72 hours

    Answer: C

    Explanation: For the specified spill, the rule says "Report by telephone within 24 hours"; the two-gallon event exceeds the one-gallon trigger.

    Reference: NAC: CHAPTER 555 - CONTROL OF INSECTS, PESTS AND NOXIOUS WEEDS — NAC 555.700 — Application of restricted-use pesticides by private applicators; subsection 2

  9. 9Why is inhalation exposure to a pesticide mist especially serious?

    1. A. Rapid absorption into the bloodstream
    2. B. Retention in airway mucus
    3. C. Conversion into less soluble material
    4. D. Delayed uptake until particles are swallowed

    Answer: A

    Explanation: The manual says pesticides can be "absorbed by the lungs where they are rapidly absorbed into the bloodstream"; that rapid uptake makes inhalation especially serious.

    Reference: General Knowledge Study Manual — p. 33

  10. 10A pesticide binds tightly to clay and organic matter. What effect does that strong adsorption generally have?

    1. A. Greater movement with soil water
    2. B. Less movement from the application site
    3. C. Greater movement as vapor
    4. D. Longer persistence before breakdown

    Answer: B

    Explanation: The manual says, "A pesticide that adsorbs to soil particles is less likely to move from the" application site; tight binding to clay and organic matter therefore reduces movement.

    Reference: General Knowledge: Pesticide Use and the Environment — p. 2
