Fusarium avenaceum is the predominant fungal pathogen responsible for root rot in Angelica crops and poses a serious threat to their commercial quality yield China. This fungus produces enniatin B (ENN B), toxin that could be pathogenicity virulence factor plant–pathogen interactions. Yet whether ENN exacerbates host infection onset of spp. caused by F. surprisingly understudied. Pathogenicity assays revealed co-inoculation with significantly increased disease index sinensis from 83.33% (pathogen alone) 92.86% (p < 0.05). Toxin degradation experiments showed bacteria Paenibacillus polymyxa Bacillus tequilensis were capable degrading 60.69% 70.02% B, respectively. Response surface optimization (24.5 °C, 22.01 mg/L 0.99% inoculum) enhanced B. 81.94%, 11.74% improvement. Three ester compounds identified LC-HRMS as potential products In planta trials demonstrated was 50.01% group co-inoculated avenaceum, 42.85% reduction compared avenaceum. study provides new microbial strategy controlling mycotoxin perspective, which can applied promote sustainable agricultural production.

Beneficial bacteria are recognised for their antimicrobial compounds, making them valuable disease control in agriculture. Bacillus species stand out stability, versatility, and selectivity as biocontrol agents. This study aimed to identify potential antagonists within the rhizosphere microorganisms by isolating bacterial strains from grapevine roots soil Moroccan vineyards. The activities of these isolates against Allorhizobium vitis, causative agent crown gall, were evaluated vitro using a disc diffusion assay, followed planta assessments under preventive simulated inoculation conditions. Screening led isolation 123 strains, with six showing strong antagonistic properties, achieving inhibition percentages up 39.6%. 16S rRNA sequencing identifying five species: B. amyloliquefaciens, velezensis, halotolerans, subtilis, anthracis. These further characterised biochemical traits plant growth-promoting abilities. Compatibility assays identified optimal combinations microbial consortia, demonstrating pathogen 37.4%. In bioassays confirmed effectiveness reducing tumour size. findings highlight agents underscore value consortia sustainable approach managing gall.

Fusarium oxysporum is a fungal plant pathogen for over 100 agricultural crop species. There are strategies managing wilt, including antagonistic bacteria that offer promising and sustainable effect. In this work, among the various endophytic bacterial strains, Paenibacillus polymyxa EB.KN35 was selected as best antifungal strain against F. oxysporum. For eco-friendly biomass production of bacterium, some byproducts were tested cultivation, soybean processing byproduct (SPBP) found to be suitable C/N source P. fermentation. The utilization 14 L bioreactor system fermentation achieved high productivity (3.46 × 1011 CFU/mL) in short time (8 h). bioactive compound analysis, secreting several growth-promoting compounds such GA3, IAA, kinetin, zeatin (via HPLC) eleven volatile GC–MS). docking study indicated (1, 2, 4, 9) may play significant role inhibiting results highlight potential reusing bioproduction with use biocontrol agent biofertilizer.
