Lentil (Lens culinaris) is moderately resistant to drought and high temperatures but sensitive to weeds such as broomrape (Orobanche crenata). The current study was aimed at the evaluation of the antimicrobial properties of L. culinaris ‘Çiftçi’ under drought and broomrape infection stresses. Antimicrobial activity of the ethanolic extract of ‘Çiftçi’ was was assayed against some test bacteria and yeast culture by the agar disc diffusion method and micro broth dilution method. The results suggested that the ethanol extracts from the different studied treatments showed antimicrobial activities, with the diameters of the inhibition zone ranging from 7.0 to 13.0 mm and 5.0 to 20.0 μg/mL, respectively. The most intensive antimicrobial activity against Proteus vulgaris ATCC 13315 was demonstrated by the extract of ‘Çiftçi’ on the 7th day grown under drought. However, only the combined stress (drought and broomrape infection) treatment has promoted antagonistic effects of the extract against Staphylococcus aureus ATCC 25923 bacteria, as compared to the control on the 7th day.
