The leaves of Pongamia glabra and Azadirachta indica reduces the population of Correct Answer Root-knot nematode

The leaves of Pongamia glabra and Azadirachta indica reduce the population of Root-knot nematode.
Root-knot nematode larvae infect plant roots, causing the development of root-knot galls that drain the plant's photosynthetic and nutrients. Infection of young plants may be lethal, while infection of mature plants causes decreased yield.
To kill nematodes in soil, heat small quantities of moist soil to 140°F in the oven or by solarization. The leaves of the above specific trees also reduce the population of nematodes.
