The increasing importance of sunflower leads to studies on seed pathogen, to guarantee crop sanity and to provide identification of pathogens in new areas. Genotypes seeds lots produced in Embrapa Soja assays carried out in tree cities of the State of Maranhão, Brazil (Balsas, São Luís and Timon) were analyzed, with the objective of evaluating sanitary quality of sunflower seeds. Sanitary analysis was performed by blotter test method and identification of fungi genera was based on morphological features. The occurrence of Fusarium sp., Alternaria spp., Curvularia sp., Dreschelera sp., Aspergillus sp., Penicillium sp., Phoma sp., Trichoderma sp., Botrytis sp., Rhizoctonia sp., Rhizopus sp., Colletotrichum sp., Chaetomium sp., Cladosporium sp. and Sclerotinia sclerotiorum was observed in seeds of sunflower, with variable incidences.
