Nicotine

Action/Use:
  • Insecticide
Use: Organophosphate insecticides have largely replaced nicotine. Two basic types of nicotine products have been marketed: alkaloid and sulfate. Nicotine alkaloid is relatively volatile and acts both by contact and by fumigant action. Had former use in greenhouse as a fumigant. The sulfate is usually marketed as an aqueous solution containing 40% nicotine equivalent. When added to alkaline water or to soap solution the alkaloid is liberated, being then more active than the sulfate alone.
