Cattleya hybrids with leaves and pseudobulbs drying
Hi
For some time me and couple of my friends(members of The Orchid Society of Karnataka, India) are having problems with grown up Cattleya hybrid plants. The symptom of leaf drying and subsequently spreading to the pseudobulb and then to other pseudobulbs and eventually the whole plant drying. I am posting some pictures. I was wondering whether it is black rot ? Can some body thow light on this with control measures. Thanks
sastry
