An insecticide whose active ingredient is nicotine, an alkaloid found in tobacco leaves. Records of tobacco being used to exterminate pests date back to the late 17th century.

Nicotinoids are generally used as an aqueous solution of sulfate (product names: Black Leaf, nicotine sulfate), and applicable pests include aphids, tail beetles, thrips, leafminers, cotton bollworms, and psyllids.
