The effect of natural products (plant extracts) in comparison with bactericide and chloramphenicol were
selected and evaluated against bacterial leaf blight pathogen, X.o.pv.oryzae. In the present study (Table 1 ),
the three plant species belonging to three different families were tested, except L. camera, which
significantly inhibited the growth of Xoo. The aqueous leaf extract of A. vasica was most effective in inhibiting
the growth of Xoo as compared to bulb extract of A. sativum.
