Resumo: Sweet corn is susceptible to the attack of various pathogens that affect its metabolism and compromise its quality and production. This study aimed to identify the causal agent of stem rot in sweet corn plants under greenhouse conditions. The identity of the pathogenic isolate was confirmed by sequencing of internal transcribed spacer (ITS1/ITS4), beta-tubulin (BT2A/BT2B), calmodulin (CL1/CL2) and translation elongation factor 1α (TEF1). The morphological and sequencing characteristics showed that Fusarium sacchari, which belongs to the Fusarium fujikuroi complex, is directly associated with the symptoms observed in the field. This fungal isolate has never been associated with diseases in Zea mays (saccharata group) in Brazil; therefore, this is the first report of the fungus infecting sweet corn in a cultivated area. KEY-WORDS: Fusarium fujikuroi, Zea mays, fungal pathogen.

Objetivou-se identificar o agente causal da podridão do colmo em plantas de milho doce, em casa-de-vegetação. A identidade do isolado patogênico foi confirmada pelo sequenciamento do espaço interno transcrito (ITS1/ITS4), beta-tubulina (BT2A/BT2B), calmodulina (CL1/CL2) e fator de elongação da tradução 1α (TEF1). As características morfológicas e de sequenciamento revelaram que Fusarium sacchari, pertencente ao complexo Fusarium fujikuroi, está diretamente associado aos sintomas observados em campo. Esse isolado fúngico nunca foi associado a doenças em Zea mays (grupo saccharata) no Brasil; portanto, este é o primeiro relato do fungo infectando milho doce em área de cultivo.
