Abstract

Anthracnose caused by Colletotrichum actuate is one of devastated disease ofpepper in Indonesia that has great impact on yield loss. Most of farmers usefungicides as controller for this disease. Application of biocontrol agentscould be one ways to control anthracnose. Beneficial microorganism such asyeast is able to be promising biocontrol agents of some pathogens, includingColletotrichum. The aim of this research was to isolate yeast from fruit andbranch as biocontrol agents for pepper anthracnose. The research results 9isolates of yeasts that were further tested against anthracnose. Isolates ofyeasts were identified as Cryptococcus terreus, C. abides var. aerius IPB 1,and C. abides var. aerius IPB 2, Candida Edam. Other isolates coded asCBN, CBM, CBK, CBF, and CBR were not identified yet. Five of potentialyeasts, Cryptococcus terreus, C. albidus var aerius IPB 1, C. albidus varaerius IPB 2, Candida edax, and unidentified yeast CBN showed directantagonist mechanism. Among of potential yeasts isolated, CBN showedability to reduce incidence of disease up to of 87.50%.Key word: Pepper, antrachnose, C. acutatum, yeast

Abstract

Endophityc fungi have been successfully isolated from Oryza sativa atLaboratory of Plant Disease, Agriculture Faculty University of Jambi. Theaim of this research was to get endophityc fungi from Oryza sativa. Therewere three (3) candidates of endophityc fungi that have been successfullyisolated. Pathogenosity test which was done showed that all of fungi wereendophityc fungi. Those fungi were identified as endophityc fungi due to theseed of paddy could growth normally in pure culture of endophityc fungi. Thethree 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 acutatum is one of devastated disease of pepper in Indonesia and has great impact on yield loss. Most of farmers use fungicides as controller for this disease. Application of biocontrol agents could be solution to control anthracnose. Beneficial microorganism, such as endophytic fungi are able to be promising biocontrol agents of some pathogens, including Colletotrichum acutatum. The aim of this research was to isolate endophytic fungi from fruit and branch as biocontrol agents for pepper anthracnose. The research resulted 11 isolates of endophytic fungi that were further tested against anthracnose. Isolates of endophytic fungi were identified as steril hifa hitam 1, steril hifa hitam 2, steril hifa 1, steril hifa 2, Nigrospora sp., Coniotyrium sp., Cylindrocarpon sp., Paecilomyces sp. The 3 of other isolates (isolat buah 5, isolat buah 1dan isolat batang 24) were not identified yet.   Keyword : Pepper, antrachnose, C. acutatum, endophytic fungi
