Inoculum (Xoo) was sub-cultured and the load was prepared by adding the sterile distilled water at 1 x1 08 CFU/ml. Inoculation was done for forty-five days old plant leaves by scissors-dip method, followed by the standard procedure of
Kauffman et al. (1973). Pre and post-inoculation applications (two days prior to and after inoculation, respectively) with aqueous extract (1 :1 0 dilution) of the leaves of selected species, streptomycin (1 00 ppm) and sterile water (control), were made at 45 days after sowing.
