Abstract

Screening of eight crops of Kharif season and three of Rabi season against a Haryana population of Meloidogyne graminicola revealed that rice, sorghum, pearl millet, wheat and oats, were good hosts of this nematode. Brinjal, tomato, okra, green gram and barley did not support the multiplication of this nematode. Few galls but with egg masses were formed on Sesbania and the use of this crop in the management of rice root-knot nematode management has been discussed. Cyperus rotundus, C. iria, Dicanthium annulaturn, Echinocloa colonum, E. crusgalli, Eclipta alba, Melilotus alba and Trigonella polycerate were found to be very good hosts of this nematode. M. graminicola completed its life cycle in 24 days in the months of July-August.
