ILLINOIS PESTICIDE APPLICATOR UPDATED
ACTUAL NEW QUESTIONS AND ANSWERS SURE
A+
✔✔Dry Flowables (DF)/Water dispersible granules (WDG) - ✔✔Similar to wettable
powders except the active ingredient is formulated into a microgranule instead of a
powder
-safer to pour
✔✔Granules (G) - ✔✔applying an active ingredient to coarse particles such as clay,
newspaper pelets, ground walnut shells or ground corn cobs
✔✔Pellets (P,PS) - ✔✔Larger than granules
-uniform weight and shape
✔✔Dusts(D) - ✔✔Contain a low percentage of the active ingredient on a very fine, dry
inert carrier such as talc, chalk, or clay
✔✔Emulsifiable concentrates (EC, E) - ✔✔When the active ingredient is soluble in oil,
but not in water
, ✔✔Emulsions - ✔✔mixtures in which one liquid is suspended as tin drops in another
liquid
✔✔Microencapsulated (ME, M) - ✔✔The active ingredient is encased in extremely
small, plastic-coated capsules; the capsules are then suspended in liquid
✔✔Flowable's or liquids (F, FL, L,) - ✔✔Presuspended WPs--offer reduced risk of
inhalation and eye exposure
✔✔Solutions (S) - ✔✔Form a true solution as in will not settle out or separate
✔✔Ultra-low-volume concentrates (ULV) - ✔✔contain a high percentage of active
ingredient in solution with a solvent (usually oil)
✔✔Aerosols (A) - ✔✔stored under pressure in cans
-low percentage of active ingredient
✔✔Poisonous Baits (B) - ✔✔pesticides mixed with water, food, or other substances
attractive to the pests
✔✔Fumigants - ✔✔substances or mixtures of materials that produce gas, vapor, fumes,
or smoke intended to control a pest
✔✔Adjuvant - ✔✔a chemical that modifies a pesticides physical properties and/or
enhances its performance
✔✔Drift reduction additives - ✔✔thickening agents that increase the droplet size and
reduce spray drift
✔✔stickers - ✔✔used to increase the adherence of the chemical to the treated surface--
increasing its persistence, particularly under adverse weather conditions
✔✔Surfactants/spreaders/wetting agents - ✔✔decrease the surface tension of water
-prevents droplets
✔✔penetrant - ✔✔used specifically to increase spray penetration into the leaf
✔✔Buffering agent - ✔✔may be added to reduce pesticide inactivation due to the pH of
the carrier
✔✔Compatibility agents - ✔✔may be added to allow the effective mixing of two or more
pesticides or a pesticide with a fertilizer
