Investigations on the recurrence and development of anthracnose disease of kidney bean (Phaseolus vulgaris) caused by C. lindemuthianum, in relation to weather variables in sub-humid mid hill areas (Zone II) of Himachal Pradesh, India, revealed that heavy and frequent rains with moderate temperatures (19-25oC) and high relative humidity (>70 %) favoured the progress of disease in terms of vertical and horizontal spread. Correlation and regression analysis of the disease with weather factors further confirmed their role in disease development.
