Pest and disease control
Neem is a key ingredient in non-
pesticidal management (NPM),
providing a natural alternative to
synthetic pesticides. Neem seeds are
ground into a powder that is soaked
overnight in water and sprayed onto
the crop. To be effective, it is
necessary to apply repeatedly, at least
every ten days.
Neem does not
directly kill insects on the crop. It acts
as an anti-feedant, repellent, and egg-
laying deterrent, protecting the crop
from damage. The insects starve and
die within a few days. Neem also
suppresses the hatching of pest
insects from their eggs. Neem cake is
often sold as a fertilizer. [4]
