Effect of Methanol Neem Extracts on Mortality of Meloidogyne incognita Juvenile

Root-knot nematode Meloidogyne incognita is regarded as one of the obstacles in the agriculturel productivity. Natural products are used as safer alternative to control root knot nematode. An experiment was carried out in vitro to test the neem plant parts methanol extract. Different concentration of shade-dried leaves, bark and seeds of neem were tested for mortality of Meloidogyne incognita juveniles. Increase in concentration and exposure period resulted in increased mortality rate of Juveniles. Methanol neem seed (5 ml concentration) proved to be the most effective among used plant parts viz. bark, leaves, and seed. Neem bark was the least effective among the three.
