Phage ɸsp1 biocontrol assay of Ralstonia solanacearum strain 1629 (R1629) on tomato seedlings in vitro. a Phage (ɸsp1) biocontrol on tomato seedlings in microcentrifuge tubes; set a—R. solanacearum strain 1629 inoculated seedling wilted in 72 h, set b—R 1629 + ɸsp1 (1 MOI) treated seedlings remained healthy, set c—uninoculated buffer control seedlings were found completely healthy. b Phage ɸsp1 biocontrol efficacy on tomato seedlings after 72 h treatment. Primary axis shows reduced pathogen count (CFU) in phage ɸsp1-treated R1629-infected tomato seedlings (R1629+ ɸsp1) compared to phage untreated, R1629-infected tomato seedlings (*p ≤ 0.0024). Secondary axis shows fresh weight of tomato seedlings in R1629 + ɸsp1-treated and phage-untreated R1629-infected tomato seedlings (# p ≤ 0.031). Data are mean values of experiment performed in triplicates with standard deviation
