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.]]>Ahmad, M.I. and T.
