Neem oil

This is an oil obtained from the neem tree, Azadirachta indica A. Juss. It has been used as an insecticide in India and Africa but is increasingly being developed as a significant commercial product. It contains a number of compounds, one of the most active being azardirachtin, which is an insect antifeedant but also shows growth inhibitory and endocrine disrupting effects. This product and its individual components is at the beginning of its commercial development, which is likely to result in a series of products as significant as those from pyrethrum.
