WASHINGTON PESTICIDE LAWS AND
SAFETY EXAM SCRIPT 2026 COMPLETE
QUESTIONS AND VERIFIED SOLUTIONS
100% ACCURATE
⩥ Acaricide. Answer: A pesticide used to control mites and ticks. A
miticide is a type of acaricide.
⩥ Acetylcholine. Answer: The primary chemical responsible for the
transmission of nerve stimuli across the synapse of two neurons or the
muscle.
⩥ Activated Charcoal. Answer: Charcoal which when finely ground
absorbs liquids and gases.
⩥ Activator. Answer: An adjuvant added to a pesticide to increase its
toxicity.
⩥ Active Ingredient. Answer: The chemical or chemicals in a product
responsible for pesticidal activity.
⩥ Acute Effects. Answer: The harmful effects that occur from a single
exposure to a pesticide by any route of entry.
,⩥ Acute Toxicity. Answer: The capacity of a pesticide to cause injury
from a single exposure. LD50 and LC are common indicators of the the
degree of acute toxicity. (See Chronic Toxicity)
⩥ Adherence. Answer: The property of a substance to stick to a given
surface.
⩥ Adjuvant. Answer: A substance added to a pesticide to improve its
effectiveness or safety. Same as additive. Examples are penetrants,
spreader-stickers, and wetting agents.
⩥ Adsorption. Answer: The process by which chemicals are held or
bound to a surface by physical or chemical attraction. Clay and high
organic soils tend to adsorb pesticides.
⩥ Adulterated Pesticide. Answer: A pesticide that does not conform to
the professed standard or quality as documented on its label or labeling.
⩥ Aerosol. Answer: A material stored in a container under pressure. An
extremely fine mist is produced when the material, dissolved in liquid, is
released into the air from the pressurized container.
⩥ Agitation. Answer: Process of a stirring or mixing in a sprayer.
,⩥ Air-Purifying Respirators. Answer: A type of protection from
pesticides that uses physical and chemical filters to trap and remove
contaminants as they pass through the device before breathed by the
wearer. They may be powered or non-powered.
⩥ Air-Supplying Respirators. Answer: A type of protection from
pesticides that provide clean, uncontaminated air from an outside source.
⩥ Algae. Answer: Relatively simple plants that contain chlorophyll and
are photosynthetic.
⩥ Algaecide (Algicide). Answer: A pesticide use to kill or inhibit algae.
⩥ Antagonism. Answer: The reduction of pesticide activity when two or
more different pesticides are mixed together.
⩥ Antibiotic. Answer: A microorganism-produced chemical that is toxic
to other microorganisms. Examples are streptomycin, cycloheximide,
and penicillin.
⩥ Anticoagulant. Answer: A chemical that prevents normal
bloodclotting. The active ingredient in some rodenticides.
⩥ Antidote. Answer: A practical treatment used to contract the effects of
pesticide poisoning or some other poison in the body.
, ⩥ Anti-Siphoning Device. Answer: A hose attachment designed to
prevent back flow into a water source. Used to prevent the flow of
pesticide mixes from spray tanks.
⩥ Anti-Transpirant. Answer: A chemical applied to a plant to reduce the
rate of transpiration or water loss.
⩥ Aquifer. Answer: A permeable zone of rock, sand, gravel, or limestone
below the earths surface saturated with water.
⩥ Arachnid. Answer: A wingless arthropod with two body regions and
four pairs of joined legs. Examples are spiders, ticks, and mites.
⩥ Arthropod. Answer: An invertebrate animal characterized by a jointed
body and limbs usually a hard body covering that is molted at intervals.
Examples are insects, mites, and crayfish.
⩥ Atropine (Atropine Sulfate). Answer: An antidote used to treat
organophosphate and carbamate poisoning.
⩥ Attractant. Answer: A substance or device to lure insects or other pests
to a trap or poison bait.
