Karnal bunt of wheat, caused byNeovossia indica (Mitra) Mundkur, was first reported in 1931 from Northwestern India in experimental plantings. For many years it was a minor disease found only in Northwestern India. During the 1969–70 crop season it was unusually widespread in Northwest India and since 1974–75 Karnal bunt has been distributed throughout Northern India from West Bengal to the western border. Seed lots with more than 50% of the kernels infected have been collected from farm…
