    Abstract

    The purpose of this research is to get the kind of filoplane fungi on onion crop which is highly potential in controlling purple blotch disease caused by the fungus Alternaria porri and to find compatible media for the development of antagonistic fungi. This research was carried out by using the antagonism test of saproba against A. porri and compatibility test of organic materials against saprobe growth. Treatment consists of extracts from cow manure and green manure. The treatment was repeated four times using completely randomized design. The results showed that the fungus saprobe that could inhibit the growth of pathogenic fungi by antibiosis come from two types of isolates,that is, Trichoderma sp. and Penicillium sp. In addition, the fungus Penicillium sp. can grow more quickly on the media with extracts from compost or green manure compared with on the cow-manure extracts media, while the fungus Trichoderma sp. can grow well on both types of media. Keywords:, Trichoderma sp. , Penicillium sp., Alternatia porri, extracted manure
