BRANCH 2 FIELD REP SAFETY REGULATORY
COMPREHENSIVE QUESTIONS AND ANSWERS
◉ 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.
