|| || || || || || || ||
What two general types of ingredients make up a pesticide formulation? - ✔✔Active and
|| || || || || || || || || || || || || ||
inert
Define active ingredient - ✔✔Toxic to the pest; effective against the target pest
|| || || || || || || || || || || ||
What are some examples of active ingredients? - ✔✔Glyphosate, carbaryl, and
|| || || || || || || || || || ||
propiconazole
Define inert agent - ✔✔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? - ✔✔Solvent, dry carrier
|| || || || || || || || || ||
,What are the three common types of mixtures? - ✔✔Solutions, suspensions, and emulsions
|| || || || || || || || || || || ||
Define solutions - ✔✔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 - ✔✔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 - ✔✔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 - ✔✔Solution, initial, isn't
|| || || || ||
Wettable powder, water dispersible granule, and dry flowable all form a ___________, have
|| || || || || || || || || || || || ||
a __________ agitation, and __________ (are/aren't) abrasive - ✔✔Suspension, strong, are
|| || || || || || || || || ||
Granule is applied ________ - ✔✔As-is || || || || ||
Solution forms a ____________________, has _____________ agitation, and ______
|| || || || || || || || ||
(is/isn't) abrasive - ✔✔Solution, initial, isn't
|| || || || ||
Emulsifiable concentrate forms a ____________________, has _____________ agitation,
|| || || || || || || ||
and ______ (is/isn't) abrasive - ✔✔Emulsion, slight, isn't
|| || || || || || ||
, Flowable/liquid forms a ____________________, has _____________ agitation, and ______
|| || || || || || || ||
(is/isn't) abrasive - ✔✔Suspension, moderate, is
|| || || || || ||
Microencapsulated formulation forms a ____________________, has _____________ || || || || || || ||
agitation, and ______ (is/isn't) abrasive - ✔✔Suspension, moderate, is
|| || || || || || || ||
What is the safety concern associated with soluble powder, wettable powder, water
|| || || || || || || || || || || ||
dispersible granule, and dry flowable? - ✔✔Inhaling dust|| || || || || || ||
What is the safety concern associated with granule? - ✔✔Feeding by birds
|| || || || || || || || || || ||
What is the safety concern associated with emulsifiable concentrate? - ✔✔Skin absorption,
|| || || || || || || || || || || ||
may degrade PPE and pump parts
|| || || || ||
What is the safety concern associated with microencapsulated formulation? - ✔✔May be
|| || || || || || || || || || || ||
toxic to bees || ||
Define fumigants - ✔✔Pesticides that form gases/vapors; most fumigants are highly toxic
|| || || || || || || || || || || ||
and require additional licensing
|| || ||
How is concentration determined for dry products? - ✔✔Percentage of active ingredient by
|| || || || || || || || || || || || ||
weight
How is concentration determined for wet products? - ✔✔Percentage of active ingredients
|| || || || || || || || || || || ||
per gallon
