or damage at which some type of pest management action must
be taken.

chemicals.
activator [ ANS: ] A adjuvant added to a pesticide to increase its
toxicity.

improve its effectiveness or safety. Examples include penetrants,
sticker-spreaders, and wetting agents.

allergic effects/allergy [ ANS: ] 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 [ ANS: ] Pesticide products that are absorbed by,
enter the tissues of, and move within the treated animal.

or more different pesticides are mixes together.
antibiotic [ ANS: ] Chemical produced by a microorganism that is

toxic to other microorganisms. Examples include streptomycin and
penicillin.
anticoagulant [ ANS: ] A chemical that prevents normal blood
clotting; the active ingredient in some rodenticides.
antidote [ ANS: ] A practical treatment used to counteract the
effects of pesticide poisoning or some other poison in the body.
anti-siphoning device [ ANS: ] A hose attachment designed to
prevent backflow of a pesticide mix from the spray tank into a
water source.
application rate [ ANS: ] The amount of pesticide that is applied to
a known area, such as an acre or 1,000 square feet or linear feet.
aquifer [ ANS: ] 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.

jointed body and limbs and usually a hard body covering that is
molted at intervals. Insects, mites, and crayfish are arthropods.
atmosphere-supplying respirator [ ANS: ] A safety device that
provides a supply of breathable air from a clean, independent
outside source. Examples include SCBA and supplied-air
respirators.
