The most readily available pesticides contain a synthetic form of nicotine, imidacloprid, which mimics the insecticidal action of real nicotine. Pesticides formulated using imidacloprid may be highly toxic to honeybees, so it should not be applied to flowering plants.
Does pesticide have nicotine?
It functions as an antiherbivore chemical; consequently, nicotine was widely used as an insecticide in the past, and neonicotinoids, such as imidacloprid, are some of the most effective and widely used insecticides.
What insecticides contain nicotine?
