Azadirachta indica, also known as Neem tree, is an evergreen plant that generally grows in the tropical and semitropical regions to heights reaching up to 20 meters. The tree is both high temperature and drought resistant with the ability to cope with water of very poor quality throughout the year. This prevents drought prone area from losing all their vegetative cover during dry periods.
The leaf of the tree is a natural mosquito repellent and is usually dried and burnt to serve this purpose. Cereals like rice and maize are preserved in storage by placing Neem leaves in the cereal to prevent weevil infestation. Some farmers grind the seeds of Neem, soak in water overnight, and spray onto their crops to act as anti-feedant, repellent, and egg-laying deterrent, protecting the crop from damage.
