ILLINOIS FIELD CROP APPLICATORS TEST
PRACTICE TEST BANK 2026 TESTED
QUESTIONS WITH ANSWERS GRADED A+
⩥ 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
⩥ Activatior adjuvants. Answer: Water spreader (surfactants), Sticker
(oils, laytex), humectant,penetrator
⩥ utility adjuvants. Answer: defoamer, water conditioner (acids)
⩥ Drift reduction additives. Answer: thickening agents increase droplet
size
Droplets must be over 200 microns
⩥ Sticker. Answer: increase adherence of chemical to surface
⩥ Surfactant, Spreaders. Answer: Spread spray mix more thoroughly
Decreases surface tension of water
⩥ Penetrants. Answer: helps pass through outer surface of plants -
through waxy coating on leaves (cuticle)
