ILLINOIS PESTICIDE APPLICATOR TEST ACTUAL
QUESTIONS AND CORRECT ANSWERS
◉ Pesticides are made up of.
Answer: Active and inert ingredients
◉ AI.
Answer: Active ingredient - chemical effective against pest
◉ Inert ingredients.
Answer: don't harm pest but make the AI more effective
◉ Herbicide formulation.
Answer: may be ready to use or may require dilution with carrier
(oil or liquid)
◉ 60WDG.
Answer: 60% AI water-dispersible granule
◉ 4EC.
Answer: 4 lbs ai per gallon of emulsifiable concentrate
,◉ SP.
Answer: Soluable powder - dry formulation. Mixed with water.
Dissolve readily and form true solution.
◉ WP, P.
Answer: Wettable Powder - dry formulation. Finely ground powder.
Forms suspension not true solution.
Abrasive, requires agitation, inhalation risk
◉ DF, WDG.
Answer: Dry flowables or water dispersible granules - dry
formulation. Similar to WP except AI is in granule instead of powder
form suspension. Less dust than WP
◉ G.
Answer: Granules - dry formulation. AI coated with clay, newspaper
Applied directly, no mixing
Low hazzard to applicators
◉ P, PS.
Answer: Pellets - dry formulation. Same as granules but larger
,◉ D.
Answer: Dusts - dry formulations.
Low percentage of AI on very fine carrier (talk, chalk, clay)
Most ready to use (no mixing)
Inhilation hazard
Drift hazzard (uncommon use)
◉ EC.
Answer: Emulsifiable concentrate - wet formulation.
AI mixed with 1+ solvents and emulsifier that allows mixing with
water
Easily absorbed through skin (dermal hazzard)
◉ ME.
Answer: Microencapsulated - wet formulation
AI is surrounded by plastic coating suspended in liquid
Time- release product
Bees catty it back to hive and can poison colony
◉ S.
Answer: Solutions - wet formulation
, Form true solution when mixed
Will not settle or separate
◉ ULV.
Answer: Ultra-low volume concentration - wet formulation
Have high % ai with a solvent (usually oil)
Low application rate per acre
◉ Fumigants.
Answer: Produce gas, vapor, fumes, etc.
Special licencing required
Highly toxic
◉ Restricted use pesticides.
Answer: Only purchased by certified applicators or persons under
their supervision
Records of applications must be maintained for 2 years
◉ Adjuvant.
Answer: Chemical modifies physical properties, enhances
performance or both of pesticides
Includes spray modifiers
