microorganisms or soil
-Acaricide - -a pesticide used to control mites and ticks. a Miticide is a type of acaricide
-Acidic - -having a ph less than 7
-Acidifiers = Buffers - -adjuvants used to retard chemical degradation of pesticides in the
spray tank by lowering the pH of alkaline water used as a diluent
-Action Threshold - -a predetermined level of pest infestation or damage at which some
type of pest management action must be taken
-Activated Charcoal - -A finely ground charcoal that adsorbs chemicals.
-Active Ingredient (AI) - -The chemical or chemicals in a product responsible for pesticidal
activity.
-Acute effect - -a symptom, illness, or injury that occurs shortly after the exposure to a
pesticide
-Acute Exposure - -An exposure to a single dose of pesticide

safety

chemical attraction
-Adulterated Pesticide - -A pesticide that does not conform to the specified standard or
quality as documented on its label or labeling

in which it is held under pressure or from a fod-generating machine
-Agitation - -The process of stirring or mixing the contents of a spray tank
, -Air-blast sprayer - -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

-Alkaline - -having a pH greater than 7, als
-Allergic Effects - -a hypersensitivity to a specific substance which is not due to the
substance's toxicity
-annual - -a plant that completes its life cycle in one year
-antidote - -a practical treatment used to counteract the effects of pesticide poisoning
-Antifouling Paint - -a paint containing a pesticide (ex: Copper) that prevents aquatic
organisms from attaching to underwater structures (such as boat hulls, crab pots and
water intake pipes)

spray tank into a water source
-application rate - -the amount of pesticide applied to a known area (such as an acre or
1,000 square feet ) volume or animal

can be drawn
-Arachnid - -a wingless arthropod with two body regions and four pairs of jointed legs
(spiders, ticks, mites)
-Arthropod - -An invertebrate animal characterized by jointed body and limbs usually a
hard body covering that is molted at intervals. Insects, arachnids, millipedes and
centipedes are arthropods
-Atropine (Atropine Sulfate) - -An antidote used to treat organophosphate and carbamate
poisoning.
-attractant - -a substance or device to lure insects or other pests to a trap or poison bait
-avicide - -a pesticide used to kill or repel birds
-Back-siphoning - -the movement of a pesticide mixture from a spray tank through the
filling hose into the water source
