Bactericidal Activity of Larrea tridentata Hydroalcoholic Extract against Phytopathogenic Bacteria

Due to the emergence of bacterial resistance in phytopathogenic microorganisms, it is necessary search for new treatment alternatives these pathogens. Natural extracts are a potential source bioactive compounds that can act against such strains. The antibacterial activity Larrea tridentata bacteria with public health importance has been documented; however, few reports cover pathogens associated agricultural sector. aim present study was evaluate hydroalcoholic extract (LTHE) and fractions bacteria. LTHE obtained by maceration technique then subjected bipartition using solvents different polarities. Clavibacter michiganensis sbsp. michiganensis, Pseudomonas syringae, Xanthomonas campestris strains were used, their antibiotic sensitivity determined. minimal inhibitory concentration (MIC) bactericidal (MBC) its (aqueous: LTAq-F; organic: LTEtOAc-F) organic fraction showed three bacteria, showing better X. campestris, exhibiting an MIC 0.39 mg/mL MBC 0.78 mg/mL. results show have vitro campestris.
