Nearly 64 MT of rice from 41 M ha is affected by various diseases. In 8 years 7 epidemics of blast occurred in 4 states. Endemic pockets, nature and recurrence of the disease are well known. There is a linear relationship between severity rating and realized yield. Y = 4306.0 - 67.7 x, where Y = estimated yield and x = the % terminal blast severity. Operational research and rice miller-sponsored IPM in selected areas, curtailed loss. Tricyclazole (Beam 0.6 g/l) as foliar spray and seed treatment with Pyroquilon (Fongorene 50 WP 4 g/kg) or Beam (4 g/kg) proved useful.
Information on bacterial blight of rice that caused epidemics in Punjab and Haryana in 1980 and 1981, Karnal bunt of wheat over North West India and 1984-85 epidemic of green ear of pearl millet in Rajasthan is presented.
