Nicotine sulphate is a compound used as a pesticide in agricultural applications. Due to its toxicity to humans and other animals, nicotine sulphate must be used with caution and only as directed. The pesticide works on many plants to kill aphids, spider mites and other insects that feed off plants. Nicotine sulphate can be purchased as a 40 per cent solution from many suppliers.

Arcos Organics supplies nicotine sulphate 40 per cent solution in 500-gram quantities. As of October 2010 the listed price was £52.3. The Acros website provides material safety data sheet information and a 3-D model of nicotine sulphate.
