POTENTIALITY OF ENDOPHYTIC FUNGI OF JUSTICIA WAYANADENSIS AS BIOAGENT AGAINST RHIZOCTONIA SOLANI

A.K. VINU AND M. JAYASHANKARA

Abstract

Seven endophytic fungi were isolated from the leaves of Justicia wayanadensis, a medicinal shrub; indigenous to Kodagu. They are Penicillium adametzi, Geosmithia sp, Penicillium chrysogenum, Gliocladium sp, Cladosporium sp and two sterile sp. Four of the isolates which were active in growth on YEMA media were selected for the antagonistic test against Rhizoctonia solani, the most common collar rot pathogen of Coffee seedlings. The isolates have shown good inhibition towards the pathogen by preventing growth against the endophyte showing clear zone. The isolate Gliocladium sp showed maximum inhibition percentage (80%) followed by Penicillium adametzi (73.3%) and P. chrysogenum (71.1%).
