Abstract

Endophityc fungi have been successfully isolated from Oryza sativa at Laboratory of Plant Disease, Agriculture Faculty University of Jambi. The aim of this research was to get endophityc fungi from Oryza sativa. There were three (3) candidates of endophityc fungi that have been successfully isolated. Pathogenosity test which was done showed that all of fungi were endophityc fungi. Those fungi were identified as endophityc fungi due to the seed of paddy could growth normally in pure culture of endophityc fungi. The three of isolated endophityc fungi were identified as Hifa steril 1, Hifa steril 2, and Fusarium sp. Keyword: endophityc fungi, Oryza sativa

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%. Key word: Pepper, antrachnose, C. acutatum, yeast
