| organophosphate pesticides | affect the nervous system by disrupting the enzyme that regulatess acetylcholine, a nuerotransmitter. They were develpped during the early 19th century, but their effects on insects, which are similar to their effects on humans, were discovered in 1932. Some are very poisonous (they were used in WWII as nerve agents). However, they usually are not persistent in the environment. |
| carbamate pesticides | affect the nervous system by disrupting an enzyme that regulates acetylcholine, a neurotransmitter. The enzyme effects are usually reversible. There are several subgroups. |
| organochlorine insecticides | were commonly used in the past, but many have been removed from the market due to their health and environmental effects and their persistence (e.g. DDT and chlordane) |
| pyrethroid pesticides | were developed as a synthetic version of the naturally occurring pesticide pytherin, which is found chrysanthenums. They have modified to increase their stability in the environment. Some are toxic to the nervous system. |
| biopesticides | are certain types of pesticides derived from such natural materials as animals, plants, bacteria, and certain minerals. Has three major classes. Canola oil and baking soda are considered this type of pesticide. |
| microbial pesticides | consist of a microorganism (e.g. bacterium, fugus, virus or protozoan) as the active ingredient.Active ingredient is specidic for its target pest(s). |
| plant-incorporated-protectants (PIP) | are pesitical substances that plants produce from genetic material that has been added to the plant. |
| biochemical pesticides | naturally occurring substances that control pests by non-toxic mechanisms. Include insect sex phermones that interfere with mating, as well as various scented plant extracts that attract insect pests to traps |
| algicides | control algae in lakes, canalc, swimming pools, water tanks, ect. |
| antifouling agents | kill or repel organisms that attach to underwater surfaces, such as boat bottoms |
| anitmicrobials | kill microorganisms (such as bacteria and viruses) |
| biocides | kill mircoorganisms |
| disinfectants and sanitizers | kill or inactivate disease-producing microorganisms on inanimate objects |
| fungicides | kill fungi (including blights, mildews, molds, and rusts) |
| fumigants | produce gas or vapor intended to destroy pests in buildings or soil |
| herbicides | kills weeds or toher plants that grow where they are not wanted |
| insecticides | kill insects and other arthropods |
| miticides | kill mites that feed on plants and animals |
| microbial pesticides | microorganisms that kill, inhibit, or out compete pests, including insects or other microorganisms |
| molluscicides | kills snails and slugs |
| nematicides | kill nematodes (microscopic, worm-like organisms that feed on plants roots) |
| ovicides | kill eggs of insects and mites |
| phermones | biochemicals used to disrupt the mating behavior or insects |
| repellents | repel pests, including insects (such as mosquitoes) and birds. |
| rodenticides | control mice and other rodents |
| defoliants | cause leaves or other foliage to drop from a plant, usually to facilitate harvest. |
| dessicants | promite drying of living tissue, such as unwanted plant tops. |
| insect growth regulators | disrupt the molting, maturity from pupal stage to adult, or other life processes of insects. |
| plant growth regulators | substances (excluding fertilizers or other plant nutrients) tha alter the expected growth, flowering, or reproduction rate of plants. |
