Abstract

Anthracnose caused by Colletotrichum actuate is one of devastated disease of
pepper in Indonesia that has great impact on yield loss. Most of farmers use
fungicides as controller for this disease. Application of biocontrol agents
could be one ways to control anthracnose. Beneficial microorganism such as
yeast is able to be promising biocontrol agents of some pathogens, including
Colletotrichum. The aim of this research was to isolate yeast from fruit and
branch as biocontrol agents for pepper anthracnose. The research results 9
isolates of yeasts that were further tested against anthracnose. Isolates of
yeasts were identified as Cryptococcus terreus, C. abides var. aerius IPB 1,
and C. abides var. aerius IPB 2, Candida Edam. Other isolates coded as
CBN, CBM, CBK, CBF, and CBR were not identified yet. Five of potential
yeasts, Cryptococcus terreus, C. albidus var aerius IPB 1, C. albidus var
aerius IPB 2, Candida edax, and unidentified yeast CBN showed direct
antagonist mechanism. Among of potential yeasts isolated, CBN showed
ability to reduce incidence of disease up to of 87.50%.
