Abiotic factors - Answer✅✅Related to nonliving elements, such as air pollutants,
wind, water, and temperature.
absorption - Answer✅✅The movement of a chemical into plants, animals (including
humans), microorganisms, or soil.
acaricide - Answer✅✅A pesticide used to control mites and ticks. A miticide is a
type of acaricide.
acidic - Answer✅✅Having a pH less than 7.
action threshold - Answer✅✅a predetermined level of pest infestation or damage
at which some type of pest management action must be taken.
activated charcoal - Answer✅✅A finely ground charcoal that adsorbs chemicals.
activator - Answer✅✅A 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✅✅Illnesses or injuries that occur shortly (within 24 hours)
after exposure to a pesticide.
acute exposure - Answer✅✅An exposure to a single dose of pesticide.
acute toxicity - Answer✅✅An injury or illness produced from a single pesticide
exposure. LD50 and LC50 are common indicators of the degree of acute toxicity.
adjuvant (additive) - Answer✅✅A substance added to a pesticide to improve its
effectiveness or safety. Examples include penetrants, sticker-spreaders, and wetting
agents.
adsorption - Answer✅✅The process whereby 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 pest control product that does not conform to
the specified standard or quality documented on its label or labeling.
advisory statements - Answer✅✅Manufacturer recommendations or best
management practices for optimal use of a pesticide product. Pesticide handlers are
not legally required to follow advisory statements.
aerosol - Answer✅✅A chemical stored in a container under pressure. An extremely
fine mist is produced when the material, dissolved in a liquid, is released into the air.
agitation system - Answer✅✅A device that stirs or mixes a pesticide product in a
sprayer.
air-blast sprayer - Answer✅✅A type of pesticide application equipment that uses a
large volume of air moving at high speed to break up and disperse spray droplets
from the nozzles.
air-purifying respirator (APR) - Answer✅✅A safety device that used filters or
sorbents to remove hazardous substances, including pesticides, from the air.
algae - Answer✅✅Relatively simple plants that are photosynthetic and contain
chlorophyll.
algaecide (algicide) - Answer✅✅A pesticide used to kill or inhibit algae.
alkaline - Answer✅✅Having a pH greater than 7 (also called basic).
allergic effects/allergy - Answer✅✅A hypersensitivity to a specific substance, often
called the allergen. An allergy may cause dermatitis, blisters, or hives. It could also
cause illness, asthma, or life-threatening shock. Often the entire body is affected.
, Pesticide allergy symptoms are similar to other allergy symptoms-reddening and
itching of the eyes, respiratory discomfort, and asthma-like symptoms.
animal systemics - Answer✅✅Pesticide products that are absorbed by, enter the
tissues of, and move within the treated animal.
annual - Answer✅✅A plant that competes its life cycle in one year.
antagonism - Answer✅✅The reduction of pesticide activity when two or more
different pesticides are mixes together.
antibiotic - Answer✅✅Chemical produced by a microorganism that is toxic to other
microorganisms. Examples include streptomycin and penicillin.
anticoagulant - Answer✅✅A chemical that prevents normal blood clotting; the
active ingredient in some rodenticides.
antidote - Answer✅✅A practical treatment used to counteract the effects of
pesticide poisoning or some other poison in the body.
anti-siphoning device - Answer✅✅A hose attachment designed to prevent
backflow of a pesticide mix from the spray tank into a water source.
application rate - Answer✅✅The amount of pesticide that is applied to a known
area, such as an acre or 1,000 square feet or linear feet.
aquifer - Answer✅✅A geologic formation from which groundwater may be drawn.
An aquifer can be a later of sand, gravel, or other soil materials or a section of
bedrock with fractures through which water can flow.
arachnid - Answer✅✅A wingless arthropod with two body regions and four pairs of
jointed legs. Spiders, ticks, and mites are arachnids.
arthropod - Answer✅✅An invertebrate animal characterized by a jointed body and
limbs and usually a hard body covering that is molted at intervals. Insects, mites, and
crayfish are arthropods.
atmosphere-supplying respirator - Answer✅✅A safety device that provides a
supply of breathable air from a clean, independent outside source. Examples include
SCBA and supplied-air respirators.
atropine (atropine sulfate) - Answer✅✅An antidote used to treat organophosphate
and carbamate poisoning.
attractant - Answer✅✅A substance or device used to lure insects or other pests to
a trap or poison bait.
