with 100% Correct Answers Already Graded A+
What is the target pest for herbicides? - (ANSWER)Weeds/Plants
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 emulsifiable concentrate? - (ANSWER)Skin absorption, may
degrade PPE and pump parts
What is the safety concern associated with microencapsulated formulation? - (ANSWER)May be toxic to
bees
Define fumigants - (ANSWER)Pesticides that form gases/vapors; most fumigants are highly toxic and
require additional licensing
How is concentration determined for dry products? - (ANSWER)Percentage of active ingredient by weight
How is concentration determined for wet products? - (ANSWER)Percentage of active ingredients per
gallon
The concentration of active ingredient in a particular formulation is always provided in the
_________________________ section of the pesticide label - (ANSWER)Product Information
Define adjuvant - (ANSWER)A chemical that modifies a pesticide's physical properties and/or enhances
its performance
What are the two classes of adjuvants? - (ANSWER)Utility agents and spray modifiers
Define utility agents - (ANSWER)Aid mixing in the spray tank; compatibility agents, pH buffering agents,
and anti-foaming agents
Define spray modifiers - (ANSWER)Aid spray application and coverage; drift reduction additives increases
droplet size and reduce drift
In spray modifiers, what do surfactants do? - (ANSWER)Help individual spray droplets spread out on the
treated surface
