Abstract

Fusarium oxysporum f.sp. vanillae is a pathogenic fungi for vanili plants. The fungi have chitin
cell wall that can be degraded by chitinase from chitinolytic Rhizoctonia binucleate of fungi.
Aim of this research was determine how the interaction between the F. oxysporum f.sp. vanillae
and Rhizoctonia binucleate were isolated from plant rizosfere. Chitinolytic activity were
measured based on the clear zone around the colony in chitin medium. Interaction of fungi were
determined by an antagonistic test. This research showed that Rhizoctonia binucleate is
chitinolytic, antagonist and alternative of biofungiside to F.oxysporum f.sp. vanillae.
