The present research, carried out in the Seed Technology and Seed Pathology Laboratortes of the ESALQ/USP, investigated the effects of sulphuric scarification and fungicides (thiabendazol, captan, thiram and iprodione + thiram) applications on the germination tests results of B. decumbens and micoflora development associated with those tests. The data analysis and results interpretations showed that: the sulphuric acid scarification did not increase significantly the germination and did not reduce the fungi development. Among the fungicides the mixture of iprodione and thiram provided the best resulls. The following fungi were identified: Alternaria tenuis, Apergillus spp., Curvularia sp., Drechslera spp., Epicoccum sp.. Fusarium sp., Neurospora monilia, Penicillium sp., Phoma sp., Rhizopus sp., Trichotheccium sp. e Triuchoconiella padwikii.
