Pathogenic fungi associated with Ageratina adenophora (Spreng.) King & H. Rob and Parthenium hysterophorus L. in Nepal

This study was carried out in Kathmandu valley, Nepal to document the fungal pathogens associated with the worst invasive species Ageratina adenophora and Parthenium hysterophorus . Pathogen infected leaves were collected in the fields and were cultured in the PDA media. The pathogenic fungi were isolated and identified. Eleven fungal pathogens, namely Alternaria sp., Fusarium sp., Cercospora partheniicola , Colletotrichum capsici , Curvularia sp., Passalora ageratinae , Chaetomium anguipilium , Cladosporium cladosporoides, and Puccinia abrupta var. partheniicola were found on Parthenium hysterophorus . In contrast, Passalora ageretinae and Cladosporium cladosporoides were found on Ageratina adenophora . Curvularia lunata was seen on both the invasive plant species.
