Abstract : The present work was conducted in Bahia, Brazil during 2005 to evaluate the pathogenicity of C. gloeosporioides [Glomerella cingulata] isolated from mango, papaya [pawpaw] cv. Sunrise Solo, guava cv. Paluma and passion fruit. The inoculation with C. gloeosporioides was through the direct method, opening a hole on the fruit and inoculating PDA disks with a mycelium of the fungus. The control was inoculated with PDA disks without the fungus. A completely randomized blocks design was used, with 25 treatments and 3 repetitions. A factorial scheme (5×5) was used for evaluations. The results obtained demonstrate that all the isolated show pathogenicity in all fruit species studied. Guava showed low susceptibility to the several isolates of C. gloeosporioides. Tommy Atkins and Rosa mangoes, and also papaya showed higher lesion growth, indicating high susceptibility.
