CA BRANCH 2 FIELD REP STUDY GUIDE
QUESTIONS WITH CORRECT ANSWERS 2026
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 ins
ecticide. 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. Les
s 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 agi
tation and remain stable for a long time. Have a greatly reduced inhalation hazard because they come
in a liquid form.
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 membr
ane 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 Aci
d Dusts, are almost totally comprised of Boric Acid and may have small amounts of other ingredients a
dded. 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 peri
meter of buildings for the control of crawling insects. Also is water activated.
Baits - correct answer-
Combination of a insecticide with an attractive carrier/food that the target pest prefers. Pheromone at
tractants are added to increase the effects. Comes in forms of gels, granules, paste, pellets, powders o
r liquids.
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.
Chronic Toxicity - correct answer-Repeated exposure over time to sub-lethal doses of chemicals.
Signal Word - correct answer-Indicates how toxic a product is and how dangerous.
Danger - correct answer-Category 1 Highly toxic LD-50 (0-
50 mg/kg) a taste to a teaspoon could kill you.
Warning - correct answer-Category 2 moderately toxic LD-50 (50-
500 mg/kg) a teaspoon to a tablespoon could kill you.
Caution - correct answer-Category 3 slightly toxic LD-50 (500-
5,000 mg/kg) an ounce to more than a pint can kill you.
