Abstract:

The southern root-knot nematode (Meloidogyne incognita) is a major soil-inhabiting plant parasite affecting plant growth and causing an estimated $100 billion yield loss per year worldwide. Synthetic pesticides, though instantaneously effective, are usually prohibitively expensive, not readily available, may cause hazards to both man and livestock, and inflict injury to the environment. Notable among the alternatives to nematicidesis the use of resistant cultivars, which are inexpensive, and eco-friendly. In the present study, seven okra (Abelmoschus esculentus L.) cultivars were evaluated for their resistance against M. incognita under field condition. Among seven cultivars none of the cultivars were found completely resistant. The cultivars ArkaAbhay and Anoop were found to be moderately resistant to M. incognita with root-knot indices of 3.0 (11 to 30 galls) at 60 days after sowing and at harvest. Arkaanamika, Usha, Rashi-20, Akshay and Solar-10 were found susceptible to M. incognita with root-knot indices of 4.0 (31 to 100 galls) at 60 days after sowing and at harvest.
