  The root and foliar diseases caused by soil-borne fungi of rice were assessed in main rice-wheat cropping areas of Punjab at the heading stage of the rice crop. Disease severity scales 0-3 and 0-5 were used for root rot and foliar diseases, respectively. The highest mean disease intensity of root rot was 58.88 in Sialkot and lowest 42.21 in Narowal. In case of foliar diseases brown spot, bacterial blight and sheath blight were 100% prevalent in Gujranwala whereas bakanae was present in traces in all four districts of Punjab. In Sheikhupura, blast was highly prevalent (20%) while in Gujranwala and Sialkot, it was absent. Sheath rot was only present in Narowal (16.66%). The highest mean disease intensity of brown spot (40), bacterial blight (44.66) and sheath blight (20) was in Gujranwala. Bacterial blight and sheath blight in Sheikhupura was 8 and 0, respectively. The highest mean disease intensity of blast was 4 in Sheikhupura and absent in Gujranwala and Sialkot. From root, foliar and soil samples Fusarium spp., Nigrospora oryzae, Helminthosporium spp., Curvularia spp., Phytophthora megasperma, Aspergillus spp., Alternaria slternata and Trichocladium spp. were isolated.

  A survey was conducted to monitor foliar and root diseases caused by soil-borne fungi at the booting stage of wheat crop in main rice-wheat cropping areas of Sheikhupura, Gujranwala, Sialkot and Narowal districts of Punjab. Foliar and root samples were collected from twenty-one key locations of four districts for the assessment of prevalence, incidence and severity of root rot and foliar spots. The highest mean incidence of root rot was 100% in Narowal and Sialkot whereas the lowest of 95% was in Gujranwala. The highest mean severity was 2.2 in Narowal while the lowest 1.5 was in Sialkot. Fusarium spp., Helminthosporium spp., Curvularia spp., Alternaria alternata, Macrophomona phaseolina, Coniothyrium spp., Mucor spp., Trichocladium spp., Rhizoctonia solani, Humicola spp. and Aspergillus spp. were isolated from the plants showing root rot symptoms. In Narowal and Sialkot the prevalence of foliar spots was 100% and in Sheikhupura 66.66%. The highest mean incidence 21.25% of foliar spots was in Sialkot and the lowest 15% was in Narowal. The highest mean severity was 4.5 in Sialkot and lowest of 3.5 in Sheikhupura. Alternaria alternata, Helminthosporium spp, Fusarium spp. and Chaetomium spp. were isolated from leaves. During this survey it was concluded that root rot was more prevalent than foliar spots. Such types of survey should be conducted every year for the situation of diseases.
