Abstract

Fusarium oxysporum f. sp. cubense (Foc) is a soil-borne pathogen causing Fusarium wilt in banana and is widely distributed in Indonesia. Biological control using antagonistic fungi is a promising strategy for managing this disease. This study was aimed to evaluate the effectiveness of indigenous root-associated fungi in controlling Fusarium wilt in banana cv. Barangan Merah. The indigenous fungal isolates and Foc were obtained from the isolate collection of the Research Center for Horticulture, BRIN, Indonesia. The experiment was arranged in a randomized block design comprising six treatments (Control, Fusarium sp. 1, Fusarium sp. 2, Fusarium sp. 3, Trichoderma sp., unidentified fungus), four replicates, and five plants per replicate. Two-month-old banana plantlets derived from tissue culture were treated by placing 15 mL of fungal propagules per plant in the soil around the roots. The study showed that the application of Fusarium sp. 2 delayed the incubation period of Fusarium wilt in banana cv. Barangan Merah to 47.33 days, compared with 30.44 days in the untreated control. Fusarium sp. 2 resulted in the lowest disease intensity (33.65%). The application of indigenous fungi did not significantly affect plant height, stem circumference, or leaf number under the experimental conditions. Fusarium sp. 2 is a promising indigenous biocontrol candidate against Fusarium wilt in banana; however, further molecular identification, pathogenicity, safety confirmation, inoculum standardization, and field validation are required before practical recommendation.
