This research aims to identify the cause of root rot in Ophiopogon japonicus plants cultivated in Zhejiang, China.
Symptoms of root rot observed in O. japonicus plants.
Fungal isolates obtained using potato dextrose agar (PDA) after surface sterilization.
Pathogenicity tested using a soil-drench method with a spore suspension of isolate OJPF07.
Root rot observed with a disease incidence of 55% in the field.
Inoculated plants showed a 100% incidence of symptoms after 30 days.
C. chloroleuca successfully reisolated from symptomatic roots, fulfilling Koch's postulates.
