- Pesticides can be classified by target organism (e.g., herbicides, insecticides, fungicides, rodenticides, and pediculicides[5] – see table), chemical structure (e.g., organic, inorganic, synthetic, or biological (biopesticide),
- although the distinction can sometimes blur), and physical state (e.g. gaseous (fumigant)).[6] Biopesticides include microbial pesticides and biochemical pesticides.
- Plant-derived pesticides, or "botanicals", have been developing quickly. These include the pyrethroids, rotenoids, nicotinoids, and a fourth group that includes strychnine and scilliroside.
- Many pesticides can be grouped into chemical families.
- Prominent insecticide families include organochlorines, organophosphates, and carbamates.
- Organochlorine hydrocarbons (e.g., DDT) could be separated into dichloro diphenyl ethanes, cyclodiene compounds, and other related compounds.
- They operate by disrupting the sodium/potassium balance of the nerve fibre, forcing the nerve to transmit continuously.
- Their toxicities vary greatly, but they have been phased out because of their persistence and potential to bioaccumulate
