Pest Control

Front 1

Abiotic

Back 1

Nonliving factors, such as wind, water, temperature, or soil type or texture

Front 2

Absorb

Back 2

To soak up or take in a liquid or powder

Front 3

Acaricide

Back 3

A pesticide used to control mites

Front 4

Accumulate

Back 4

To increase in quantity within an area, such as the soil or tissues of a plant or animal

Front 5

Acetylcholine

Back 5

An enzyme that transmits nerve signals between nerves and muscles, sensory organs, or other nerves

Front 6

Acetylcholinesterase

Back 6

An enzyme that deactivates acetylcholine to allow the nerve signals to stop. Organophosphate and carbamate pesticides block the action of acetylcholinesterase, resulted in loss of control of nerve function.

Front 7

Acidifier

Back 7

An adjuvant used to lower the p H (or acidify) the water being mixed with a pesticide. Pesticides off and break down more slowly if the spray water is slightly acid. Acidifiers are also referred to as acidulators.

Front 8

acidulator

Back 8

see acidifier.

Front 9

Activator

Back 9

An adjuvant that increases activity of a pesticide by reducing surface tension or speeding up penetration through insect or plant cuticle.

Front 10

Active ingredient (a.i.)

Back 10

The material in the pesticide formulation that actually destroys the target pest or performs the desired function.

Front 11

Addictive effect

Back 11

An increase in toxicity brought about by combining one pesticide with another. The increased toxicity is no greater than an equal volume of either pesticide is used alone, however.

Front 12

Adjuvant

Back 12

A material added to a pesticide mixture to improve or alter the deposition, toxic effect, mixing ability, persistence, or other qualities of the active ingredient.

Front 13

Absorb

Back 13

To take up or hold on surface.

Front 14

Aerosol

Back 14

Very fine liquid droplets or dust particles often emitted from a pasteurized can or aerosol generating device.

Front 15

Aestivation

Back 15

Dormancy during summer or periods of high temperature or dry season.

Front 16

Agitator

Back 16

A mechanical or hydraulic device that stirs the liquid in a spray tank to prevent the mixture from separating or settling.

Front 17

Alga

Back 17

An aquatic, nonvascular plant. (plural: algae)

Front 18

All-terrain cycle

Back 18

A three or four wheeled motorcycle-like vehicle used for applying low volumes of pesticides in agricultural areas and open lands.

Front 19

Amphibian

Back 19

A cold blooded organisms such as a frog, toad, or salamander.

Front 20

Anemometer

Back 20

An instrument used for measuring wind speed.

Front 21

Anionic

Back 21

Negatively charged; a characteristic of some types of surfactants which help prevent pesticides from being washed off treated surfaces.
