Exam With Answers
GSPCC - correct-answer -Georgia Structural Pest Control Commission
GDA - correct-answer -Georgia Department of Agriculture
Emulsifier- detergent like material that will allow oil droplets to be suspended in
water
Advantages of EC:
Little visible residue
Easy to mix
Not abrasive
Will not plug screens or nozzles
Little agitation needed=will not separate when equipment is running
Disadvantages of EC:
Easily absorbed through skin of human or animal
Solvents may damage rubber/plastic hose, gaskets, and pump parts if left over
night

May cause discoloration of painted finishes or harm plants (phytotoxicity)
Porous surfaces may absorb the formulation
Flammable
Microencapsulated Pesticides (ME or FM)
Advantages or Disadvantages: - correct-answer -Made by enclosing tiny droplets
of the active ingredient in small polymer (gel like material) beads in a liquid
formulation.
The active ingredient is released when the polymer breaks down.
These are usually diluted before application.
Advantages of ME:
Remains on the surface of porous surfaces
Low toxicity to plants
Provides a longer residual because of the slow release of AI
Disadvantages of ME:
Requires frequent agitation to keep the power from settling to the bottom of the
tank
Leaves visible residue

Wettable Powder (W or WP)
Advantages or Disadvantages: - correct-answer -Dry formulation that has the
active ingredient that has the AI attached to a powder particle.
Wetting agent is added to the formulation before application. Wetting agent
creates a suspension, powder does not dissolve, it is suspended (floating/sinking)
in the wetting agent.
Advantages of WP:
Remains on the surface of porous surfaces
Low toxicity to plants
Not readily absorbed in the skin of humans and domestic animals
Disadvantages of WP:
Requires frequent agitation to keep the power from settling to the bottom of the
tank
Leaves visible residue
Easily inhaled when mixing
Wear on spray applicator due to abrasion of powder
Water Dispersable Granules (WDG)
, 4|Page
Advantages or Disadvantages: - correct-answer -Similar to Wettable Powder but
the particle size is not a dust like powder, WDG granules are small easily measured
granules which are less likely to get airborne and be inhaled during
mixing/measuring.
Advantages of WDG:
Reduced risk of inhalation
Disadvantages of WDG:
Application equipment must have good agitation to suspend heavy granules
Dusts (D)
Advantages or Disadvantages: - correct-answer -Powder of AI mixed with an inert
ingredient (clay or talc).
Ready to use, dry formulation.
Dermal, Ingestion, or drying out the insect and drying out all internal water
(desiccants)
Ineffective when damp. Too thick a layer imposes risk of human inhalation.
Advantages of D:
Long residual life, if kept dry
