Abstract

The present study, was carried out to investigate the antibacterial properties of aqueous, acetone and methanol extract of Aphelonix persica galls at the concentrations of 10, 50 and 100 mg/ml  were screend against four bacteria (Xanthomonas axonopodis pv. phaseoli of bean common blight disease, E. amylovora of fire blight of apples and pears, Agrobacterium tumefaciens of crown gall and Psuedomonas syringae pv. tabaciof tobacco blight ). The antibacterial activity was measured from the size of the diameter of zone inhibition in agar subculture and disc diffusion methods. The results indicated a positive correlation between zone of inhibition diameter and the extract concentrations. Based on the inhibitory concentration, E. amylovora and Agrobacterium tumefaciens had the lowest while,Xanthomonas axonopodis pv. phaseoli and Psuedomonas syringae pv. tabaci had the highest inhibition against  different concentrations of aqueous, acetone and methanol extracts.
