Data collected by mobile surveys in 1976-84 revealed the gradual increase in the incidence of Neovossia [Tilletia] indica. The disease has spread to new areas of W. Bengal and Gujerat in addition to Punjab, Haryana, Delhi, Uttar Pradesh, low altitudes in Himachal Pradesh, Jammu, northern parts of Bihar, Rajasthan and Madhya Pradesh. It was not found in Maharashtra, Orissa, Assam, Karnataka, Andhra Pradesh, Tamil Nadu or Kerala. During 1980-84 severity was greatest in 1982, followed by 1981 and 1983. Increase in spread seems to be affected by growing susceptible cultivars.
