Meloidogyne hapla

A survey was conducted in Kodaikanal hills of Tamil Nadu, India to know the association of root-knot nemtode, Meloidogyne hapla in carrot (Daucus carota subsp. sativus). The nematode was found in eight carrot growing villages surveyed at Kodaikanal. Infestation was high (150-300 nematodes/200 cm3 soil) at Poomparai followed by moderate (50-150 nematodes/200 cm3 soil) at Poondi, Kookal, Mannavanur and Shenbananur villages.

A study was carried out to evaluate ten grapevine cultivars against root-knot nematode Meloidogyne hapla under polyhouse condition. The cultivars showed varying degree of susceptibility against nematodes in relation to nematode infestation and plant growth parameters. None of the grapevine cultivars used in the study was found to be highly resistant or resistant against M. hapla. Gall index was maximum in cultivar Pusa Navroz (4.8) followed by Sahebi (4.6), Hussaini (4.5) and Thompson seedless (4.0) and they were categorized susceptible to M. hapla.
