In Indian scenario, Chrysanthemum white rust is an emerging disease, which is reported during 2015 under Bengaluru conditions, India. The occurrence of this disease coincides with post-monsoon season followed by winter spell. In this paper, we are reporting occurrence of this disease during monsoon season. This occurrence is correlated with the prevailing weather conditions during same period. We found that due to pre-monsoon rain, the temperature falls down and become favorable for white rust initiation. Popular variety of chrysanthemum among farmer of called ‘Marigold’ was found severely infected with white rust.
