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

19. Algaecide (algi- a pesticide used to kill or inhibit algae
cide)
20. Alkaline having a pH greater than 7, als
21. Allergic Effects a hypersensitivity to a specific substance which is not due to the substance's
toxicity
22. annual a plant that completes its life cycle in one year
23. antidote a practical treatment used to counteract the effects of pesticide poisoning
24. 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)
25. Antisiphoning a mechanism that prevents back flow of a pesticide mix from the spray tank into
Device a water source
26. application rate the amount of pesticide applied to a known area (such as an acre or 1,000 square
feet ) volume or animal
