Abstract
Two phage strains for Xanthomonas translucens f. sp. oryzicola, the incitant of bacterial leaf streak disease of rice have been isolated from the diseased rice leaves collected from Pantnagar (SP1) and Cuttack (SP2). The plaque size of the two phages vaired considerably and the thermal inactivation range slightly.
Of the 15 isolates of X. translucens f. sp. oryzicola only 7 isolates were susceptible to one or both of the phage strains, which were classified into 3 lysotypes. The phage strain SP1 lysed 19 out of 30 isolates of X. oryzae tested whereas SP2 lysed X. corchori and X. amorphophalli only.
