摘要：

Nematicidal property was identified for the first time in root tubers of Flemingia procumbens, an underutilized native crop species grown in the tribal tracts of Khasi and Jaintia hills of Meghalaya, India. In vitro studies were conducted on second stage juveniles (J2s) of root-knot nematode, Meloidogyne incognita, which is a most economically important and commonly found nematode in cultivated fields. Powder extract of small, medium and large size tubers of F. procumbens was tested in vitro against J2s of M. incognita. All the three types of powder extracts were found effective and caused varied mortality in J2s of M. incognita in the range of 88–95% at 100 mg/ml after 72 h exposure. The methodology developed is based on preliminary study and can be standardized for precision following further research investigations. © 2019, Indian Phytopathological Society.
