ABSTRACT = {The tomato (<i>Solanum lycopersicum</i> L.) is one of the world’s most important vegetable crops. Still, phytopathogenic bacteria affect the yield and quality of tomato cultivation, like <i>Agrobacterium tumefeciens</i> (<i>At</i>), <i>Clavibacter
michiganensis</i> subsp. <i>michiganensis </i>(<i>Cmm</i>), <i>Pseudomonas syringae pv. tomato</i> (<i>Pst</i>), <i>Ralstonia solanacearum</i> (<i>Rs</i>),
and <i>Xanthomonas axonopodis</i> (<i>Xa</i>). Synthetic chemical products are used mostly on disease plant control, but
overuse generates resistance to bacterial control. This study aimed to evaluate the <i>in vitro</i> antibacterial activity
of the ethanolic extract of <i>Moringa oleifera</i> Lam. leaves against <i>At</i>, <i>Cmm</i>, <i>Pst</i>, <i>Rs</i>, and <i>Xa</i>, as well as information
about this plant species’ chemical composition. Antibacterial activity against pathogens observed by microplate
technique, phytochemical screening, and FTIR analysis revealed different bio-active compounds on ethanolic
extracts with antibacterial activity. The growth inhibition rate ranged between 0.08% and 99.94%. The inhibitory
concentration, IC50, required to inhibit 50% of <i>At</i>, <i>Cmm</i>, <i>Pst</i>, <i>Rs</i>, and <i>Xa</i> bacterial growth, was 276.67, 350.48,
277.85, 351.49, and 283.22 mg/L, respectively. Inhibition of phytopathogen bacteria’s growth increased as the concentrations of the extract also increased. <i>Moringa oleifera</i> extract can be recommended as a potent bio-bactericide.},
