BRANCH 2 PRACTICE TEST ACTUAL EXAM
PAPER 2026 QUESTIONS WITH ANSWERS
GRADED A+
⩥ 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.
