With Correct Answers
Falsifiable concentrates (EC or E) - correct-answer -Formulations made up of the
technical material, solvents and emulsifiers. Some agitation is required. Once dry,
pesticide residue is barley visible.
Wettable Powder (WP) - correct-answer -These formulations are made by
impregnating or coating an appropriate powder with the technical insecticide.
Wettable Powders do not dissolve in water and frequent agitation is usually
required. Heavy applications may leave visible deposits.
Soluble Powders (SP) - correct-answer -May look like Wettable Powders but they
dissolve and form true solutions when dilute with water. Less visible than
Wettable Powders after drying, Frequent agitation is not required.
Suspension Concentrates (SC) - correct-answer -Products made with small
particles suspended in oil solvents or water. Easy mix, require little or no agitation
and remain stable for a long time. Have a greatly reduced inhalation hazard
because they come in a liquid form.
,2
Flowable Liquids - correct-answer -Contains concentrated water dispersible
powders in a liquid form. These powders may stay suspended for a long time.
Flowable liquids are easy to handle and have excellent dilution properties.
Microencapsulated Formulations (ME) - correct-answer -manufactured by
suspending liquid or solid pesticide particles in microcapsules. By altering the
membrane of the microcapsules, the residual performance, speed and action and
odor can be affected. May clog sprayers and leave visible residue.
Dusts (D) - correct-answer -Made by combining and insecticide with a dust diluent
(usually inert) Some products such as Boric Acid Dusts, are almost totally
comprised of Boric Acid and may have small amounts of other ingredients added.
Drifts are a major issue.
Granules - correct-answer -Made by coating or impregnating an inert carrier with
an insecticide. Made of materials, such as, clay, corn cobs, pecan shells, saw dust,
etc. Formulations are ready to use and used mostly for exterior perimeter of

Fumigants - correct-answer -toxic gases such as methyl bromine that are used to
kill pests.
Vitamin-K - correct-answer -The antidote to consuming Anti-coagulants.
LD-50 - correct-answer -the amount of a chemical that kills 50% of the animals in
a test population.
LC-50 - correct-answer -the lethal concentration in air or water required to kill
50% of the population.
Acute Toxicity - correct-answer -adverse effects occur within a short period after
exposure to toxin.
Structural Pest Control Board - correct-answer -Consist of seven members. Four
public members and three are members of the pest control industry. The
Governor appoints two public members and three licensed industry members.
