A new leaf spot disease of Pterygota alata (Roxb.) R. Br. Caused by Corynespora cassiicola (Berk. & Curt.) Wei was recorded from forest nurseries and a young planted stand at Lacchiwala and Satyanarayan in and around Dehra dun. About 15-40% of the leaf area was damaged by the pathogen. The disease may be controlled by foliar application of a mixture of Dithane M-45 (0.2%) and Bavistin (0.1%).
