Abstract Plant diseases significantly threaten global food security, with viral infections, particularly Watermelon Mosaic Virus (WMV), causing substantial losses in economically important crops such as squash. This study aims to investigate the efficacy of beneficial bacteria isolated from various plants promoting growth and mitigating effects WMV Understanding interactions between microbes could provide sustainable solutions for managing infections agriculture. Sixty-two bacterial isolates were obtained rhizosphere basil, mint, thyme, squash plants. Among these, six strains exhibited notable plant growth-promoting activities, including synthesis indole acetic acid, solubilization phosphate zinc, ammonia production, activity 1-aminocyclopropane-1-carboxylate deaminase (ACCD). Morphological observations 16S rRNA gene sequencing identified these Pseudomonas indica , Bacillus paramycoides thuringiensis mycoides Paenibacillus glucanolyticus Niallia circulans .
