CORE MANUAL PESTICIDE FORMULATIONS 04

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.

2. Which is the pesticide formulation process by
which solid particles are dispersed in a liquid?

Emulsion.
Solution.
Suspension.

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).

4. Which liquid pesticide formulation may
approach 100% active ingredient?

Aerosol (A).

Emulsifiable concentrate (EC).

Ultra-low volume (ULV).

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

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).

7. Which type of dry/solid pesticide formulation
consists of particles that are the same weight
and shape?

Bait.
Granule.
Pellet.

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.

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.

10. Which type of adjuvant increases the viscosity
of spray mixtures?

Sticker.
Extender.
Thickener.
