TAILIEUCHUNG - Detection and molecular characterization of black spot disease of papaya (Carica papaya L.) incited byasperisporium caricae (Speg.) Maubl

Black spot of papaya caused by Asperisporium caricae incidence was recorded in five different localities viz., Pasur, Telungupalayam, Thondamuthur, Vedapatti and TNAU orchard of Coimbatore district. Per cent disease severity (PDS) ranged from 1 to 29 per cent on leaves. The fungal pathogen associated with black spot of papaya was isolated and identified as Asperisporium caricae based on morphological characters. Severe disease incidence was observed from November to January and no disease incidence was recorded during summer. Pathogenicity test was proved on young papaya plants under glasshouse conditions twenty days after inoculation. Molecular confirmation of Asperisporium caricae through 18S rRNA gene sequencing gave an amplicon size of 560bp size. The isolate Asperisporium caricae was sequenced and submitted to NCBI database with the accession number MK879405. The present study was aimed to characterize the pathogen responsible for black spot of papaya and confirmation by molecular methods. | Detection and molecular characterization of black spot disease of papaya (Carica papaya L.) incited byasperisporium caricae (Speg.)
