Abstract
Diversity of microbial rhizosphere in rice farm underpins organic matter, plant health, and yield. The study aims to characterize morphologically fungal rhizosphere in organic rice farms and to test its potential as biological control agent against rice blast disease in vitro. 100 g bulk soil associated with root system obtained from organic rice farm in Kajang, District of Bulukumba. The result shows fungal diversity and population dynamic was discovered including Trichoderma spp, Penicillium spp, Gliocladium sp. Aspergillus flavus, A. fumigatus, A. niger, Curvularia sp. All fungal microbial rhizosphere are able to colonyze rice blast disease patogen, Pyricularia grisea in vitro test.
Keywords: fungal rhizosphere, organic farm, biological control, blast disease, population
