Abstract

Fusarium wilt caused by Fusarium oxysporum is one of the most destructive soil-borne diseases affecting banana (Musa paradisiaca) cultivation, with potential crop losses reaching up to 50%. This study aims to evaluate the antagonistic potential of Trichoderma spp. isolated from the rhizosphere of coffee plants as a biological control agent against F. oxysporum under in vitro conditions. The research was conducted at the Laboratory of Pests and Plant Diseases, Faculty of Agriculture, Universitas Malikussaleh, using a Completely Randomized Design (CRD) with 13 Trichoderma isolates and three replications. The dual culture method was applied to assess antagonism, and the data were analyzed using ANOVA and Duncan's Multiple Range Test (DMRT) at a 5% significance level. The results showed that isolate G2DTLD had the highest inhibition zone against F. oxysporum, with 74,72% on the 5th day and 80,59% on the 7th day. The lowest inhibition was observed in isolates G3DTLM and G1DTLD. The inhibitory effect of Trichoderma spp. was attributed to mechanisms such as nutrient competition, hyperparasitism, and antibiotic production. This study supports the potential of Trichoderma spp. as an eco-friendly biological control agent against F. oxysporum in banana crops.
