Natural organic compounds produced by plants that are poisonous, particularly to insects, are known as <u>Botanicals</u>.
Botanical insecticides are naturally occurring chemicals (insect toxins) extracted or derived from plants or minerals. They are also called natural insecticides. Organic gardeners will choose these insecticides, in some cases, over synthetic organic materials.
Pesticides are substances that are meant to control pests. This includes herbicide, insecticide, nematicide, rodenticide, bactericide, insect repellent, fungicide, and lampricide.
Examples of plants that are sources of commercially available botanical pesticides include pyrethrum (Tanacetum cinerariifolium), neem (Azadirachta indica), sabadilla (Schoenocaulon officinale), tobacco (Nicotiana tabacum) and ryania (Ryania speciosa)
