Anthracnose caused by Colletotrichum spp. may result in great losses in field productions and post-harvest conditions for several cultures and their products. The objective of this work was to test the pathogenicity of C. gloeosporioides isolates from cashew (Anacardium occidentale) (CAJ), mango (Mangifera indica) (MG), papaya (Carica papaya) (MM) and passion fruit (Passiflora edulis) (MR) and C. musae from banana (Musa spp.) (BAJ); to evaluate the production of extra cellular hydrolytic enzymes (amylolytic, celullolytic, lypolytic, proteolytic) by the isolates on specific solid culture media; and to detect electrophoretic patterns of total proteins and isoenzymes (alpha-esterase, beta-esterase, acidic phosphatase and leucine aminopeptidase). In crossed pathogenicity tests, all Colletotrichum spp. isolates produced necrotic and depressed lesions on fruits, except on passion fruit, which was susceptible only to the MR isolate. The isolates of C. gloeosporioides produced amylolytic, lypolytic, proteolytic, and celullolytic enzymes, and C. musae did not produce any detectable celulase. Electrophoretic analysis of total proteins and isoenzymes showed variations in the number and position of the bands among all isolates in the systems used, except for leucine aminopeptidase, which was monomorphic.
