JAMUR RIZOSFER SEBAGAI AGEN ANTAGONIS PENGENDALI PENYAKIT LAPUK FUSARIUM PADA BATANG TANAMAN KARET (HEVEA BRASILIENSIS MUELLARG)
ABSTRACT: The stem rot disease
caused by the Fusarium sp. fungus is one of the diseases found on the rubber
tree (Hevea brasiliensis). This plant disease can be controlled by using a
biological agent namely the rhizosphere fungus which is antagonistic to
pathogenic fungi. This research aimed to find out the types of fungi from the rhizosphere
of rubber tree and to find out the ability of those fungi to inhibit the growth
of Fusarium sp. The Fusarium sp. fungus was isolated using the direct planting
method, the rhizosphere fungus was isolated using the dilution method, the
antagonistic test was conducted using the paired method. The rhizosphere fungi
successfully isolated were Trichoderma sp. W1, Penicillium sp.1 W2, Penicillium
sp.2 W3, Chaetomium sp. W4. The research findings showed that there was
inhibition of the growth of Fusarium sp. by Trichoderma sp. with the highest
antagonistic percentage by 51.08%.
