This disease is a severe pathogen to this crop. This study aims to identify the potential biocontrol agent against wilt disease as a fungicide alternative. Forty-seven isolates were evaluated for antagonistic activity against <em>F. udum</em> by dual culture method. Interaction of <em>F. udum</em> and antagonistic bacteria was studied in potato dextrose agar (PDA) under in vitro conditions and lysis of fungal hyphae was observed by using Scanning Electron Microscope. Dry weight of <em>F. udum</em> mycelium was recorded after 3 days of co-inoculation with the rhizobacteria in PDB. Potential antagonistic bacterial isolates were further used for enzymatic assay in vitro conditions. Molecular characterization of bacteria was done by using primers based on hydrolytic genes like chitinase and 1,3-glucanase related genes, amplified at 402 and 750 bp, respectively. Out of forty-seven bacterial isolates used to assess their antagonistic activity, only eight isolates, viz., <em>Bacillus amyloliquefaciens</em> CFLB 31, <em>Bacillus velezensis</em> CFLB 24, <em>Bacillus subtilis</em> CFLB 11, <em>Stenotrophomonas rhizophila</em> CFLB 26, <em>S. matalophila</em> CFLB 47, <em>Microbacteria</em> sp. CFLB 28, <em>G.nicotiana</em> CFLB 18 and <em>Pseudoarthrobacter </em> sp. CFLB 36 showed the promising antagonistic activity against <em>F. udum</em> with 70–84% inhibition in a dual culture plate assay. Among them, three <em>Bacillus</em> species (<em>B. amyloliquefaciens, B. velezensis, B. subtilis)</em> and <em>S. maltophilia</em> CFLB 47 were found to be the most effective biocontrol agent against <em>F. udum</em> under in vitro conditions. Lysis of fungal hyphae was also noted during interaction of fungus and bacteria on PDA. These isolates were screened for production of hydrolytic enzymes activities and they showed positive for production of pectinase, protease and cellulase under in vitro conditions. These isolates amplified chitinase and β-1, 3-glucanase-related genes at 402 and 750 bp, respectively. In addition, bacterial strains reduced the mycelium weight of <em>F. udum</em> with the range of 58.42 − 86.84% during co-inoculation in PDB. However, <em>B. amyloliquefaciens</em> had the highest percentage of biomass reduction, up to 86.84%. Bacterial treatments are considered beneficial and nature-friendly.

In the mimicked infection condition, seven gene clusters, including the GtPKS1 cluster, exhibited upregulated expression. Through comparative genomic analysis, GtPKS1 was associated with the production of dichlorodiaporthin, a metabolite with cytotoxic and antifungal activity. In addition, GtPKS10 and GtPKSNRPS3 showed similarities to already characterized biosynthetic pathways involved in the synthesis of ACR-toxin (phytotoxic) and trichosetin (phytotoxic and antibiotic), respectively. These three gene clusters were further scrutinized through phylogenetic inference, which revealed the distribution of orthologous sequences across various plant-associated fungi.
