An extensive survey conducted during 2004 and 2005 revealed presence of angular leaf spot in all cucumber growing areas of Kashmir valley with incidence and intensity ranging between 23.3 to 74.4% and 10.5 to 26.0%, respectively. Symptoms initiated as minute water-soaked spots on leaves, which turned angular, light tan in colour and necrotic later on. The spots on infected fruits were small, water-soaked and circular, which later coalesced and become sunken with whitish centres and raised margins. Tissues underlying such spots turned brown leading to rot and misshapen fruits in case of severe infection. The causal bacterium obtained from diseased leaves and seeds was identified as Pseudomonas syringae pv. lachrymans.
