APPLICATOR EXAM 2026 UPDATE
QUESTIONS AND CORRECT VERIFIED
ANSWERS ALREADY GRADED A+
(BRAND NEW VISION)
Commercial and private applicators may be fined for violation of Act 451,
Natural Resources and Environmental Protection, Part 83, Pesticide
Control. (True or False?) - ans-True
Who investigates complaints about pesticide misuse and pesticide
failures? - ans-MDA investigates pesticide misuse and EPA
investigates pesticide failures.
The ______________________administers both the federal (RCRA) and state
(Act 64) hazardous waste regulations. - ans-MDNR
Plastic pesticide containers may be recycled only if they have been triple-
rinsed or power-rinsed and there are no visible signs of residue. (True or
False?) - ans-True
Which state law requires employers to obtain and retain MSDS sheets on
all hazardous chemicals on site? - ans-MIOSHA
What are inorganic pesticides? - ans-They are of mineral origin and
therefore do not contain carbon.
Do organic pesticides contain carbon? - ans-Yes
Synthetic organic pesticides are... - ans-man-made, carbon-containing
chemicals
,What is a "Mode of Action"? - ans-A pesticide's mode of action is the
method by which it kills or adversely affects the target pest.
Protectants - ans-Products to prevent pest establishment.
Sterilants - ans-Pesticides that manage pests by rendering them
incapable of normal reproduction are known as sterilants.
Selective - ans-A pesticide is selective if it is effective against one
type of organism and not another.
Nonselective - ans-When a pesticide kills or adversely affects many
organisms in a target site, it is considered nonselective.
Broad-Spectrum - ans-Pesticides that control a wide range of pests
are considered broad-spectrum. They are sometimes labeled as
multipurpose pesticides.
Contact - ans-Pesticides that kill or adversely affect pests simply
by contacting them are known as contact pesticides.
Systemic - ans-Pesticides that are absorbed by one part of the
animal or plant and distributed internally to other parts of the
animal or plant are systemic pesticides.
Persistent - ans-Persistent pesticides remain active for a period of
time after application and give continued protection against the
pest.
Nonpersistent - ans-Pesticides that control pests at the time of
application and then break down quickly are nonpersistent.
,Active Ingredient - ans-The component of a pesticide that controls
the target pest.
Pesticide Formulations - ans-Mixtures of active and inert ingredient
How can you reduce pest resistance? - ans-When making repeated
pesticide treatments to a system or area for the same pest, using
pesticide products with different modes of action as well as other
pest control methods (such as sanitation, crop rotation, etc.) is
recommended.
Emulsifiable Concentrates (EC) - ans-An emulsifiable concentrate
formulation usually contains a liquid active ingredient, one or
more petroleumbased solvents and an agent that allows the
formulation to be mixed with water to form an emulsion. An
emulsion is one liquid dispersed, usually as very small drops,
throughout another liquid
How much active ingredient is found in a gallon of EC? - ans-Each gallon
of EC usually contains 25 to 75 percent (2 to 8 pounds) active
ingredient. EC's are among the most versatile formulations.
Solutions (S) - ans-Some pesticide active ingredients dissolve
readily in a liquid solvent, such as water or a petroleum-based
solvent. When mixed with the solvent, they form a solution that
will not settle out or separate.
Flowables (F or L) - ans-Some active ingredients are insoluble
solids. These may be formulated as flowables in which the finely
ground active ingredients are mixed with a liquid, along with
inert ingredients, to form a suspension.
Aerosols (A) - ans-These formulations contain one or more active
ingredients and a solvent. Most aerosols contain a low
percentage of active ingredient. There are two types of aerosol
, formulations — the ready-to-use type, and those made for use in
smoke or fog generators.
Formulations for smoke or fog generators - ans-These aerosol
formulations are not under pressure. They are used in machines
that break the liquid formulation into a fine mist or fog (aerosol)
using a rapidly whirling disk or heated surface.
Granules (G) - ans-Granular formulations are similar to dust
formulations except that granular particles are larger and
heavier.
Granular pesticides are most often used to apply chemicals to the
soil to control weeds, nematodes and insects living in the soil.
Wettable Powders (WP or W) - ans-Wettable powders are dry, finely ground
formulations that look like dusts. Usually they must be mixed with water
for application as a spray. Wettable powders contain 5 to 95 percent
active ingredient, usually 50 percent or more.
Wettable powders are one of the most widely used pesticide formulations.
They can be used for most pest problems and in most types of spray
equipment where agitation is possible.
Soluble Powders (SP or WSP) - ans-Soluble powder formulations look like
wettable powders. However, when mixed with water, soluble powders
dissolve readily and form a true solution.
The amount of active ingredient in soluble powders ranges from 15 to 95
percent; it usually is over 50 percent. Soluble powders have all the
advantages of wettable powders and none of the disadvantages except
the inhalation hazard during mixing. Few pesticides are available in this
formulation because few active ingredients are soluble in water.
