Neem is a tree and it is native to India,Burma, Bangladesh, Sri Lanka,Malaysia and Pakistan. The botanical name of Neem tree is Azadirachta indica. The seeds of neem contain a complex secondary metabolite namely azadirachtin.

All parts of a neem tree such as bark, leaf and seed having medicinal properties. Neem used as antifungal, antibacterial, antiviral agent. It also used as spermicidal agent.

Now days the mortality rate of neem trees are high. Why????????????

Is it due to climate change? Is any biological warfare against neem?

Biological warfare means the use of disease causing microorganisms to kill human, animals and plants. Is any chance to biological warfare against neem trees?
