CORE MANUAL PESTICIDE FORMULATIONS 04

  1. 1. The name “X-Pest 5G” on a pesticide label
    indicates a:

    Granular pesticide with 5% active ingredient.
    Granular pesticide with 5% inert ingredients.
    Gel pesticide with 5% active ingredient.
    A. Granular pesticide with 5% active ingredient.
  2. 2. Which is the pesticide formulation process by
    which solid particles are dispersed in a liquid?

    Emulsion.
    Solution.
    Suspension.
    C. Suspension.
  3. 3. Which liquid pesticide formulation consists of
    a small amount of active ingredient (often 1%
    or less per unit volume)?

    Microencapsulated (M).

    Ready-to-use (low-concentrate) solution
    (RTU).

    Ultra-low volume (ULV).
    • B. Ready-to-use (low-concentrate) solution
    • (RTU).
  4. 4. Which liquid pesticide formulation may
    approach 100% active ingredient?

    Aerosol (A).

    Emulsifiable concentrate (EC).

    Ultra-low volume (ULV).
    C. Ultra-low volume (ULV).
  5. 5. Which is a disadvantage of both EC and ULV
    formulations?

    Difficult to handle, transport, and store.

    Require constant agitation to keep in
    suspension.

    Solvents may cause rubber or plastic hoses,
    gaskets, pump parts, and other surfaces to
    deteriorate
    • C. Solvents may cause rubber or plastic hoses,
    • gaskets, pump parts, and other surfaces to
    • deteriorate
  6. 6. Which dry/solid formulation is mixed in
    water and reduces the risk of inhalation
    exposure during mixing and loading?

    Soluble powder (SP).

    Water-dispersible granule (WDG) or dry
    flowable (DF).

    Wettable powder (WP).
    • B. Water-dispersible granule (WDG) or dry
    • flowable (DF).
  7. 7. Which type of dry/solid pesticide formulation
    consists of particles that are the same weight
    and shape?

    Bait.
    Granule.
    Pellet.
    C. Pellet.
  8. 8. Which is an advantage of microencapsulated
    materials?

    Delayed or slow release of the active
    ingredient prolongs their effectiveness.

    Their pesticidal activity is independent
    of weather conditions.

    They usually require only short restrictedentry
    intervals.
    A. Delayed or slow release of the active ingredient prolongs their effectiveness.
  9. 9. Which type of adjuvant functions as a wetting
    agent and spreader (i.e., physically altering
    the surface tension of spray droplets)?

    Buffer.
    Extender.
    Surfactant.
    C. Surfactant.
  10. 10. Which type of adjuvant increases the viscosity
    of spray mixtures?

    Sticker.
    Extender.
    Thickener.
    C. Thickener.
