Abstract
Dyschoriste nagchana Nees (Acanthaceae) is a perennial plant grows naturally in wet grassland, but is now often also found in secondary bushland and grassland, including lawns. In January2019, severe powdery mildew symptoms were observed on the leaves and stem of D. nagchana (Fig.1, a). The infection was found to be very severe at that time on plant and because of severe infestation premature leaf fall was also observed. The occurrence of powdery mildew in its anamorphic form on D. nagchana. was first observed in the ranges of hills in Western Ghats pertaining to district Satara viz Yavateshwar (17°41’02.91”N 73°56’58.15”E and Elevation 3419ft) and Varoshi (17°52’04.42” N 73°45’03.12” E and Elevation 2834ft). later on, disease incidence was noticed from different areas of said district.
