Abstract:
An experiment was conducted during the cropping season of 2021 and 2022 to assess the influence of several meteorological parameters on the development of anthracnose disease in ‘Falguni’ variety of french bean. The influence of two-year meteorological data i.e. temperature relative humidity, sunshine hours and rainfall were analyzed and correlated with the disease severity. The results revealed that the initial disease severity was recorded in the 16^th standard meteorological week (SMW) which was 2.86 per cent during the first year and was 1.09 per cent in the second year. However, during both the years temperature showed a positive and significant correlation with the disease severity. On the basis of two-year weather data, co-efficient of determination (R²) revealed a strong relationship among the disease severity and the selected weather variables viz., temperature, relative humidity, sunshine hours and rainfall that contributed 94 and 99 per cent variation towards disease severity during the year 2021 and 2022, respectively.
