Niembaum
Farmers lacking access to, or sufficient cash for, manufactured synthetic acaricides often use various herbal treatments, locally available. Nicotine from treated tobacco leaf is an example, but such unregistered preparations require careful use to avoid poisoning or skin damage. Commercially formulated botanical acaricide may often be available in tropical regions, containing the active ingredient azadirachtin. This is extracted as neem oil from fruits and seeds from the neem tree, "Azadirachta indica".
