CA Branch 2 Field Rep Study Guide Practice Exam
UPDATED 2025/2026 WITH CORRECT/ACCURATE
ANSWERS
Falsifiable concentrates (EC or E)
Ans: Formulations made up of the technical material, solvents and emulsifiers. Some agitation
is required. Once dry, pesticide residue is barley visible.
Quiz Wettable Powder (WP)
Ans: 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.
Quiz Soluble Powders (SP)
Ans: 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.
,Quiz Suspension Concentrates (SC)
Ans: 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.
Quiz Flowable Liquids
Ans: 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.
Quiz Microencapsulated Formulations (ME)
Ans: 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.
Quiz Dusts (D)
Ans: 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.
Quiz Granules
, Ans: 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.
Quiz Baits
Ans: 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.
Quiz Fumigants
Ans: toxic gases such as methyl bromine that are used to kill pests.
Quiz Vitamin-K
Ans: The antidote to consuming Anti-coagulants.
Quiz LD-50
Ans: the amount of a chemical that kills 50% of the animals in a test population.
Quiz LC-50
Ans: the lethal concentration in air or water required to kill 50% of the population.
