Insecticides (Latin insecta = insect, caedere = to kill) are chemical or biological agents. They belong to the group of pesticides.

Insecticides act as contact, feeding or respiratory poisons on insects. Insects as pests in viticulture were already combated in ancient times because, unlike micro-organisms, they were visible as enemies of the vine.
