tailieunhanh - Cultural and morphological variability among the isolates of sclerotium rolfsii sacc. causing wilt complex disease of betelvine (Piper betle L.)

Wilt complex is one of the important diseases of betelvine causing severe losses in betel leaf production. In the present study Cultural characters of Sclerotium rolfsii was studied on six different solid media. Among the solid media tested, maximum radial growth was observed on potato dextrose agar and oat meal agar. Ten isolates of S. rolfsii collected from different locations of northern Karnataka were studied on potato dextrose agar for their cultural and morphological variability. | Cultural and morphological variability among the isolates of sclerotium rolfsii sacc. causing wilt complex disease of betelvine Piper betle L.
