Abstract

Plants are constantly exposed to and threatened by a variety of pathogenic microorganisms present in their environments. Xanthomonas campestris is a major plant pathogen in the world. It is known to cause significant losses in many crop plants due to leaf spot and leaf blight. In the present study, bacteria isolated from infected Citrus limon fruit and identified by 16S rDNA sequencing was X. campestris. In vitro antimicrobial properties of 100 essential oils were evaluated against X. campestris. The chemical composition of the most active essential oils was investigated by gas chromatography–mass spectral (GC–MS) analysis. The potential of these essential oils as ecofriendly and economical biocontrol in agriculture is discussed.
