    Abstract

    Narrow brown leaf spot (NBLS) caused by Cercospora oryzae Miyake is one of the important obtacle in rice cultivation that can decrease the productivity up to 40%. It has been known well that some phyloplane fungi are antagonistic to some leaf diseases. Phyloplane fungi of rice however haven’t been studied much and poorly understood as biological control agent of rice pathogen such C. oryzae. The research aimed to study the antagonism of some phyloplane fungi of rice against C. oryzae. At least 14 isolates of phyloplane fungi were succeeded to collect consisting of six pathogenic and eight non pathogenic. All of non pathogenic isolates were antagonistic against C. oryzae both in vitro and just isolate one isolate could not inhibit the infection of the pathogen in vivo. Some isolates were identified as Aspergillus, Mucor, Penicillium, Fusarium, and Trichoderma. The isolate of Mucor and Fusarium could inhibit highestly the growth of pathogen on potato dextrose medium that were at 36.0% and 35.5% respectively. Whereas on artificial inoculation on rice, some isolates such Penicillium and Fusarium could inhibit most effectively and significantly different to Mencozeb application with dosage 5g L-1
