Abstract:

A survey was conducted in the major acidlime growing areas of Tenkasi and Madurai districts of Tamil Nadu. The causal agent of citrus canker (Xanthomonas axonopodis pv. citri) was isolated from the plant samples collected during the survey. The isolated bacterial colonies were found to be yellow pigmented with entire margin and the cells were single rod shaped under Gram’s staining. The efficacy of some antibiotics namely Streptomycin, Tetracycline, Streptomycin + Tetracycline, Cefatoxime, Cefixime, Gentamycin, Amoxillin and chloramphenicol each at the concentration of 100, 250 and 500 ppm were evaluated against the virulent isolate of the pathogen. Among the various antibiotics, Cefatoxime (39.07mm) and Cefixime (34.18mm) showed maximum average inhibition zone followed by Tetracycline (29.51mm).
