Potensi Kolonisasi Mikoriza Arbuskular dan Cendawan Endofit dan Kemampuannya dalam Pengendalian Layu Fusarium pada Bawang Merah
Abstract
Colonization Potential of Arbuscular Mycorrhiza and Endophytic Fungi and Its Effectiveness in Control Fusarium Wilt on Shallot
Fusarium wilt is an important disease on shallot (Allium cepa var. Aggregatum) due to Fusarium oxysporum f.sp. cepae. The research aimed to study colonization of arbuscular mycorrhiza and endophytic fungi, and their biocontrol performance against fusarium wilt disease of shallot. The experiment was performed using a completely randomized design with 8 treatments and 5 replications. The effectiveness of biocontrol agents on the progress of fusarium wilt was observed from the percentage of agent biocontrol colonization¸ disease latent periode¸ disease incidence¸ rate of infection¸ and area under disease progress curve. The biocontrol agent tested successfully symbiotic in the root tissue of shallot. The single application of arbuscular mycorrhizal showed the best influence on plant growth and suppressing the progress of fusarium wilt in shallots with the longest disease latent period at 21 days and decreasing disease incidence up to 40%.
