White powder was seen on upper side of some tulsi leaves. Also the leaves showing powdery mass had turned reddish-brown in colour. The powdery mass when seen through foldscope showed large number of microscopic fungal spores – probably conidia. On the conidiophores, the point of attachment of conidia were clearly marked. Besides, the spores were oval in shape, with double layered wall and a plug-like struture at the tip.
