Abstract:

Rice root-knot nematode Meloidogyne graminicola causes yield losses of up to 18% in rainfed upland rice in eastern India, and seedling blight disease of rice, caused by Sclerotium rolfsii, is seen to be associated with it (Mathur 1973). This observation led to the investigation of the nature and type of association among rice cultivar IR8, M. graminicola, and S. rolfsii.

Samples of IR8 plants with an intact root system and rhizosphere soil collected from the 0-5-cm depth of a rainfed upland rice field served as a source of inoculum for the greenhouse experiments.
