### pesticide:

Rotenone
* acts more slowly and works as both a contact and stomach poison
  - on the respiratory tissues, including nerves and muscles
  - slowly and is quickly degraded upon exposure to sunlight
* are chemical compounds
* broad spectrum poison mainly used to control leaf-eating caterpillars and beetles.
* broad-spectrum insecticide that is derived from the roots of a tropical plant.
* can kill fish.
* chemical pesticide used to control fish populations and as a sampling aid
  - used to renovate fish populations
* comes from the root of the derris plant
  - roots of legume plants that grow in South America and the East Indies
* common ingredient in fish toxicants
  - insecticide that is perceived in many quarters as relatively innocuous
  - pesticide used to kill fish
* degrades rapidly when exposed to air and sunlight.
* disrupts cellular respiration and death is relatively slow compared to most nerve toxins.
* general use pesticide.
* highly active but short-lived photosensitizer.
* is also very toxic to pigs
  - widely used in liquid form by fishery managers to destroy pest species
* is an inhibitor of oxidative phosphorylation
  - insect stomach and contact poison
  - organic product made from extracts of tropical plants
  - unstable compound that breaks down when exposed to the environment
  - available in some gardening stores as a natural insecticide
  - derived from the roots of certain tropical plants
  - effective against a wide range of insects and has a short residual life
* is extracted from the roots of derris plants in Asia and cube plants in South America
  - with acetone or ether and the concentrate is used to make products
  - extremely poisonous to fish
  - fairly unstable, with a half life of under a week
  - highly toxic to fish
  - moderately toxic to most mammals, but is extremely toxic to fish
  - more toxic by inhalation than by ingestion
  - only very slightly mobile in soil
  - produced from the roots of two tropical members of the bean plant family
  - reported to be a mild skin irritant
  - restricted in some states and is toxic to birds, fish, and honeybees
  - safe for all livestock except swine, which are sensitive to the compound
* is the most effective and readily available of the non-synthetic insecticides
  - used in the agricultural arena as an insecticide
  - very toxic to fish
* kills by preventing gill-breathing fish, amphibians, and invertebrates from using oxygen
  - fish by inhibiting their ability to utilize oxygen for metabolism
* lasts a week or less after application because it is rapidly degraded by sunlight.
* mixture of natural compounds found in the roots, seeds and leaves of various plants.
* natural substance derived from several tropical and sub-tropical plants.
* naturally occurring substance found in the roots and stems of several tropical plants
  - produced, biodegradable product obtained from the tropical cube root
* naturally-derived chemical that is considered an 'organic' pesticide.
* plant-derived pesticide used by organic gardeners.
* poison commonly added to insecticides.
* registered aquatic chemical that is used to kill fish.
* restricted-use pesticide.
* selective, non-specific botanical insecticide with some acaricidal properties.
* stops insect feeding and is broad spectrum in action.
* type of rat poison which blocks the first step of the electron transport chain.
* works by inhibiting a biochemical process in fish cells.

Several pesticide
* are available for grub control.
* break down rapidly in alkaline water.
* provide excellent protection against parasites.

Synthetic pesticide
* are more of a threat to man than the insects
  - poisonous compounds designed to kill insects, weeds and fungal pests
* have in some way a harmful affect on our earth's fragile ecosystem.

Systemic pesticide
* Most systemic pesticide has effects.
* are required once leaf curling has occurred.
* work differently.
