Abstract

Rust of sorghum (Puccinia purpurea Cook) is becoming a serious problem in rabi sorghum. In India, it is recorded in all states. The present study were carried out during rabi 2014-15 on the evaluation of nine fungicides for management of sorghum rust and loss estimation in grain and fodder yield due to disease. The result indicated that the minimum disease intensity after first spray and second spray was recorded in treatment hexaconazole (5.99% and 7.32%) followed by difenconazole (6.32% and 7.67%), these fungicides gave 71.61, 84.16 per cent and 70.04, 83.41 per cent disease control, respectively. However, the numerically more grain yield was recorded in treatment difenconazole (12.13 qt/ha) with 16.74 per cent increase in grain yield over control. Maximum fodder yield (44.40 qt/ha) was recorded in spray treatment of hexaconazole (0.1%) with 17.21 per cent increase over control.
