ILLINOIS PESTICIDE APPLICATOR TEST FULL
SOLUTION STUDY GUIDE
◉ What is the target pest for insecticides?
Answer: Insects
◉ What is the target pest for fungicides?
Answer: Fungi
◉ What is the target pest for miticides (acaricides)?
Answer: Mites/ticks
◉ What is the target pest for repellents?
Answer: Insects/vertebrates
◉ What two general types of ingredients make up a pesticide
formulation?
Answer: Active and inert
◉ Define active ingredient
Answer: Toxic to the pest; effective against the target pest
,◉ What are some examples of active ingredients?
Answer: Glyphosate, carbaryl, and propiconazole
◉ Define inert agent
Answer: Does not have direct effect on the pest; added to make the
product safer, more effective, or easier to use
◉ What are some examples of inert ingredients?
Answer: Solvent, dry carrier
◉ What are the three common types of mixtures?
Answer: Solutions, suspensions, and emulsions
◉ Define solutions
Answer: Mixtures formed by dissolving a substance in a liquid; will
not "settle out" and do not require agitation to keep the components
in solution
◉ Define suspensions
Answer: Mixtures formed by dispersing fine solid particles in a
liquid; the solid particles do not dissolve in the liquid carrier;
,suspensions must be agitated to maintain uniform particle
distribution
◉ Define emulsions
Answer: Mixtures in which one liquid is suspended as tiny droplets
in another liquid; for example, emulsifiable concentrates (EC) have
active ingredients that are dissolved in an oil solvent and an
emulsifying agent is added so that the formulation can be
conveniently mixed with water to form an emulsion
◉ Soluble powder forms a ____________________, has _____________
agitation, and ______ (is/isn't) abrasive
Answer: Solution, initial, isn't
◉ Wettable powder, water dispersible granule, and dry flowable all
form a ___________, have a __________ agitation, and __________
(are/aren't) abrasive
Answer: Suspension, strong, are
◉ Granule is applied ________
Answer: As-is
◉ Solution forms a ____________________, has _____________ agitation, and
______ (is/isn't) abrasive
, Answer: Solution, initial, isn't
◉ Emulsifiable concentrate forms a ____________________, has
_____________ agitation, and ______ (is/isn't) abrasive
Answer: Emulsion, slight, isn't
◉ Flowable/liquid forms a ____________________, has _____________
agitation, and ______ (is/isn't) abrasive
Answer: Suspension, moderate, is
◉ Microencapsulated formulation forms a ____________________, has
_____________ agitation, and ______ (is/isn't) abrasive
Answer: Suspension, moderate, is
◉ What is the safety concern associated with soluble powder,
wettable powder, water dispersible granule, and dry flowable?
Answer: Inhaling dust
◉ What is the safety concern associated with granule?
Answer: Feeding by birds
◉ What is the safety concern associated with emulsifiable
concentrate?
