Author(s):

Abstract:
Karnal bunt caused by Tilletia indica Mitra (Neovossia indica Mitra (Mundkur) was first recorded in April, 193from Botanical Research Station, Karnal (Haryana) on wheat cultivar, foundation and Punjab A.The disease was prevalent in the sub-continent since long, infecting native wheat grown over North Western India but it never caused serious yield reduction.However, the disease appeared in serious proportions in early 1970s with the introduction of dwarf Mexican Wheat Varieties into India and Pakistan.Till 1974-75 the disease remained restricted to Jammu and Kashmir, Punjab and Tarairegion of Uttar Pradesh. The disease in seed,soil and air borne in nature and difficult to manage and different strategies like crop rotation, delayed sowing, avoiding excessive use of nitrogenous fertilizer and irrigation are no more tenable in present day intensiveagriculture.Studies indicated that varieties like Raj-3077, HD-2733, NW-1012, K-307, K-9423 and DBW-17 are safer against the disease.Due to very-very low disease incidence the results regarding the suitability of sowing date and fertilizer levels found inconclusive.
