Abstract: | Plants interact with a wide variety of pathogenic organisms by virtue of their sessile lifestyle. The Pantoea agglomerans and Erwinia chrysanthemi are major plant pathogen amongst them. They are known to cause significant losses in many crop plants. In the present study, bacteria isolated from infected Cajanus cajan and Arachis hypogaea seed are identified by 16S rDNA sequencing as P. agglomerans and E. chrysanthemi, respectively. In vitro antimicrobial properties of 100 essential oils (EOs) were evaluated against P. agglomerans and E. chrysanthemi. The chemical composition of most active EOs was investigated by gas chromatography–mass spectral analysis. The potential properties of these EOs as ecofriendly and economical biocontrol in agriculture is discussed. |
