Biochemical fungicides and bactericides derived from plant extracts are also known as botanical fungicides and botanical bactericides. Botanical "cides" are naturally occurring chemicals extracted from plants and they often overlap with biochemical insecticides. The modes of action often have synergistic capabilities so a fungicide or bactericide can also act as an insecticide.
