Intercropping impact on root-gall nematode on Pumpkin (Cucurbita moschata Poir) cv. Large Red Local.

Six intercrops (Vinca rosia, maize, basil), coriander, amaranthus & red pepper) were tested to manage root-gall nematode disease of pumpkin (Cucurbita maxima) in a loamy soil naturally infested with Meloidogyne javanica. Results based on root-gall indices and number of juveniles (J₂) recovered from roots and rhizospheric soil showed that intercropping of pumpkin with, basil and amaranthus effectively suppressed infection on pumpkin roots. Coriander, maize and red pepper, intercropped with the pumpkin aggravated root-gall damage and caused yield reduction.
