Forecasting late blight of potatoes in the hills of West Bengal
- 8 Downloads
Climatological data showing the favorable periods and incidence of late blight for seven consecutive years from 1952 to 1958 were studied by the “moving graph” method of Hyre. The “moving graph,” using a 7-day total rainfall instead of a 10-day total, proved to be more accurate in forecasting late blight in the Darjeeling hills of West Bengal.
The average 10-day rainfall in Darjeeling is 2.60 inches and the 7-day total rainfall is calculated to be 1.82 inches.
