The anthracnose disease caused by Colletotrichum musae on banana was controlled
by biological control agents. Seven isolates of C. musae were collected from banana growing
area in Suphanburi, Nakhonpathom, Ratchaburi and Nonthaburi province, Thailand.
Pathogenicity was tested on fresh banana, and proved that isolates CMDC-01 and CMNM-01
were most aggressive isolates. These isolates were molecular phylogeny confirmed species. In
vitro test was done by dual culture tecnique, two isolates of pathogen were tested against ten
isolates of antagonistic fungi (Neosartorya hiratsukae, N. pseudofischeri, N, aureola, N.
spinosa, N. fenneliae, Talaromyces muroii and T. trachyspermus). The result showed the best
antagonistic isolate was N. pseudofischeri EU13 which inhibited C. musae CMDC-01 of 51.23%
and N. fenneliae CHA03-A11 inhibited C. musae CMNM-01 of 59.85%.
