Summary
An account is given of the incidence of blast disease of rice in correlation with some meteorological factors. The results show that forecasting of blast outbreak in India can be attempted on the basis of minimum night temperature range of 20°–26°C. in association with a high relative humidity range of 90% and above lasting for a period of a week or more during any of the susceptible phases of crop growth,viz., seedling stage, post-transplanting, tillering stage and at neck-emergence.
