Abstract

ABSTRACTFungal diversity of chili rhizosphere at conventional and organic cropping system and its role as biocontrol agent of Colletotrichum gloeosporioides. The aim of this research was to study fungal diversity in chili rhizosphere at conventional and organic system; to ditermine and identify the fungi that had antagonistic activity against C. gloeosporioides. Diversities of rhizosphere fungi in chili of conventional and organic system were determined by counting the amount of propagule and isolates. Antagonistic activity was examined by dual cultures and slide culture. Identification was determind up to genus level. Propagule density and the amount of isolates in chili rhizosphere of organic system were higher than those in conventional system. Fifty two fungal isolates were found from chili rhizosphere at conventional and organic system, 28 isolates from organic system and 24 isolates from conventional. Ten fungal isolates from chili rhizosphere in organic system and 4 fungal isolates from that in conventional system had antagonistic activity against C. gloeosporioides which cause antracnose on chili. The antagonistic isolates were: Trichoderma, Paecilomyces, Aspergillus and unidentified isolate (X isolate).
