Abstract:
Potato cultivation is hampered by a host of factors among which fungal diseases play a leading role. Nevertheless, our knowledge on phytofungal diversity inciting diseases at the early developmental stages of potato is limited at present to some few traditionally recognized pathotypes. In this present study, potato farms were surveyed for two and a half years and predominant fungi causing disease at the early stages of potato development were identified using standard taxonomic monographs and ribosomal DNA locus. It was found that Ascomycetes viz. Colletotrichum gloeosporioides, Cochliobolus lunatus, Aspergillus terreus, Aspergillus fumigatus, Nigrospora oryzae, Fusarium culmorum, Pestalotiopsis vismiae, Phomopsis asparagi, Dothiorella gregaria, Didymella cucurbitacearum, Stagonosporopsis cucurbitacearum and Penicillium citrinum incite diseases of potato at the early developmental stages. This study provide a comprehensive overview of the genetic diversity of Ascomycetes thriving on potato plants and evidence that Aspergillus species are harmful pathogens causing loses to potato cultivation.
