Abstract:

Black spot disease is serious threat to rose production in India. Black spot of rose caused by Marssonina rosae (Lib.) Lind. with its perfect stage Diplocarpon rosae (Wolf) causes heavy losses to roses worldwide. Therefore preliminary investigations were undertaken with the objective to record the outbreak of black spot of rose in Solan and Sirmour districts of Himachal Pradesh, India. The pathogen was identified based on the morphological features as Marssonina rosae (Lib.) Lind. Most distinguishing morphological features of pathogen were production of cylindrical, two celled and hyaline conidia measuring in length (22.1 – 25.3 µm) and width (5.3 – 7.1 µm). The pathogenicity was obtained within 15days of inoculation.


Keywords: Conidia, pathogenicity, Marssonina rosae
