These methods will be described in a future FACT Sheet. Neem oil and neem seed cake . Neem oil is used as fuel for lamps, an antiseptic for animal wounds, a lubricant for machinery, an insect repellent, to remove tobacco suckers, and in the production of soap, toothpaste and cosmetics. It has also traditionally been used for a variety of medicinal purposes, but there is evidence that it should not be ingested orally. Neem seed cake is the residue left after the oil has been extracted from the kernel.
Neem cake is used as a fertilizer with insecticidal and fungicidal effect.
Silviculture Propagation . Neem seedlings can be produced vegetatively by air layering, cuttings, grafting and tissue culture, however, they are usually grown from seed in nurseries as bare-root stock or in containers. Direct sowing is more cost-effective, but may result in poor survival in drier zones. Neem wildlings are an inexpensive source of seedlings, as natural regeneration is normally abundant. Although neem is a prolific seed producer, seed supply is frequently a problem.
