acaricide - ANSWER A pesticide used to control mites and ticks. A miticide is a kind of acaricide.
Acidic - ANSWER Having a pH less than 7
acidifier - ANSWER Same as BUFFER.
Action Threshold - ANSWER A predetermined level of pest infestation or damage at which some type of
pest management must be taken
Activated charcoal - ANSWER A finely ground charcoal that adsorbs chemicals.
active ingredient (AI) - ANSWER the chemical or chemicals in a product responsible for pesticidal activity
acute effects - ANSWER a symptom, injury, or illness that occurs shortly after exposure to pesticide
acute exposure - ANSWER An exposure to a single dose of pesticide.
Acute Rodenticide - ANSWER A pesticide that is capable of killing a rodent after a single feeding.
acute toxicity - ANSWER The ability of a pesticide to cause illness after a single exposure. LD50 and LC50
are common indicators of the degree of acute toxicity.
,Adjuvant (or additive) - ANSWER A substance added to a pesticide to improve its effectiveness or safety.
absorption - ANSWER the process whereby chemicals are bound to a surface by a physical or chemical
attraction
Aquifer - ANSWER A geological formation (sand, gravel, bedrock) from which groundwater can be drawn
arachnid - ANSWER a wingless arthropod with two body regions and four pairs of jointed legs (spider,
tick, mite)
Arthropod - ANSWER An invertibrate animal characterized by a jointed body and limbs and usually a hard
body covering that is molted at intervals. Insects, arachnids, millipedes, and centipedes are arthropods.

Biennial - ANSWER A plant that completes its life cycle in two years.
bioaccumulation - ANSWER The process by which animals store chemicals in their tissues
Biological control - ANSWER the control of pests using predators, parasites, and disease-causing
organisms
biomagnification - ANSWER the process bywhere some organisms accumulate chemical residues in
higher accumulations than those found in the organisms they consume
biopesticide - ANSWER a pesticide derived from naturally occuring materials
Boom - ANSWER A pipe that is attached to a sprayer that has nozzles fixed along its length
Botanical Pesticides - ANSWER A pesticide produced from naturally occurring chemicals inside of plants
(Pyrethrum)
Brand Name - ANSWER The unique name under which a registered pesticide product is sold
