Three major groups or families of insecticides are inorganic compounds (sulfur), organic
compounds (rotenone and pyrethrum), and synthetic organic compounds, which are
further subdivided into chlorinated hydrocarbons (DDT), organophosphates (Parathion,
Malathion), and carbamates (carbaryl/Sevin

Six different ways in which insecticides work to control insects include:
 Stomach poisons, which kill insects that eat part of the plant
 Contact poisons, which kill insects that are hit by or otherwise touch the poison
 Systemic poisons that affect the entire plant and are effective in the control of insects
with either chewing or sucking mouth parts
 Fumigants, which are actually contact poisons applied in gaseous form
 Repellents, which generally do not kill insects but drive them away before they
attack the plant
 Attractants and pheromones, which lure insects to their deaths

A Safety Data Sheet (SDS) is a document that gives detailed information about a pesticide
product and company identification, composition/information on the ingredients,
hazard identification, first aid measures, firefighting measures, accidental release
measures, handling and storage, exposure control/personal protection, physical and
chemical properties, stability and reactivity, toxicological information, ecological
information, disposal considerations, transport information, other pertinent safety
information

A toxic chemical is one that is poisonous or injurious to humans and other animals.
Acute toxicity is a measure of how poisonous a pesticide is after a single exposure.
Pesticides are generally rated according to acute toxicity. Chronic toxicity is a measure of
how poisonous a pesticide is over a period of time and after repeated exposure. Chronic
toxicity is a danger of chemicals that accumulate in the body, such as chlorinated
hydrocarbons.
