Karnal bunt is an important designated disease of wheat adversely affecting the yield and trade globally. The disease is seed, soil and air borne causing qualitative and quantitative losses in terms of quality and seed yield. The affected seeds are partially or completely converted into black powdery mass. The disease has become a limiting factor in the export of wheat because the importing country insists on zero tolerance levels for the fear of introducing the disease. The management of the disease through sprayings of fungicides/bioagents during heading stage of the crop appears to be the best and most important option. Efficacy of different fungicides, bio-agents and their combinations were assessed against the disease in wheat variety HD 2687 during Rabi 2006-07 and Rabi 2007-08 as foliar sprays at the time of anthesis. Foliar application of 0.1% Tilt (0.06%), 0.25% Vitavax Power (0.06%), 0.05% Tilt+0.4% Tv (0.07%), 0.05% Tilt (0.07%), 0.125% Bavistin+0.4% TV (0.08%) were found most effective and were statistically at par as against control
(0.28%).
