CA Branch 2 Field Rep Study Guide Questions
With Correct Answers 100% Verified.
Falsifiable concentrates (EC or E) - 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) - 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) - 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) - 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.
Flowable Liquids - 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) - 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) - 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 - 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 buildings for the control of crawling insects. Also is
water activated.
Baits - Answer✔Combination of a insecticide with an attractive carrier/food that the target pest
prefers. Pheromone attractants are added to increase the effects. Comes in forms of gels,
granules, paste, pellets, powders or liquids.
Fumigants - Answer✔toxic gases such as methyl bromine that are used to kill pests.
Vitamin-K - Answer✔The antidote to consuming Anti-coagulants.
LD-50 - Answer✔the amount of a chemical that kills 50% of the animals in a test population.
LC-50 - Answer✔the lethal concentration in air or water required to kill 50% of the population.
Acute Toxicity - Answer✔adverse effects occur within a short period after exposure to toxin.
Chronic Toxicity - Answer✔Repeated exposure over time to sub-lethal doses of chemicals.
Signal Word - Answer✔Indicates how toxic a product is and how dangerous.
Danger - Answer✔Category 1 Highly toxic LD-50 (0-50 mg/kg) a taste to a teaspoon could kill
you.
Warning - Answer✔Category 2 moderately toxic LD-50 (50-500 mg/kg) a teaspoon to a
tablespoon could kill you.
Caution - Answer✔Category 3 slightly toxic LD-50 (500-5,000 mg/kg) an ounce to more than a
pint can kill you.
Type of pesticide - Answer✔General terms what type of pests are to be controlled and also type
of formulation.
Net Contents - Answer✔Found on the front of the label along the bottom edge
Indicates the quantity of formulation in the package
Expressed in weight, volume, or count.
(EPA) Registration and Establishment Numbers - Answer✔Indicates the pesticide has been
registered. Number will tell you which location and facility the product was made at.
EPA - Answer✔Environmental Protection Agency.
Precautionary Statement - Answer✔Protection precautions of applicators and other people or
animals who may be exposed to the product. Will see heading (Hazards to humans and
domestic animals)
