Abstract
The study showed that Geranium leaf spot disease which occurred at Omar Al-Mokhtar University gardens, El-Beida city is caused by two species of bacteria belonging to the genus Corynebacterium that were identified as C. kutscheri and C. xerosis. This study constitutes the first record of this disease in Libya. The anti-bacterial activity of streptomycin at a concentration of 10 ppm on the two species of bacteria gave inhibition zones of 9.3 and 7.2 mm diam, respectively, whereas the antibiotic balkacyline produced inhibition zones of 6 and 5 mm with C. xerosis at concentration of 250 and 100 ppm, respectively
