Question : 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.
Question : 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.
Question : 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.
Question : 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.
Question : 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.
Question : 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.
Question : Dusts (D)

CORRECT ANSWER : the lethal concentration in air or
water required to kill 50% of the population.
Question : Acute Toxicity
CORRECT ANSWER : adverse effects occur within a short
period after exposure to toxin.
Question : Chronic Toxicity
CORRECT ANSWER : Repeated exposure over time to sub-
lethal doses of chemicals.
