Fusarium moniliforme is an important pathogen associated with corn seeds, causing seed rot and poor stands. The present work was conducted to verify the effect of the storage of corn seeds for twelve months in a cold chamber (14 °C and 40% RU) and in an uncontrolled environment on the survival of F. moniliforme. The results showed that the fungus was less affected when the seeds were maintained in a cold chamber, if compared to uncontrolled storage conditions and that the loss of viability varied, depending on the seed lot assayed. In some samples, with initial incidences of 28, 34 and 59%, kept in an uncontrolled environment after 12 months had incidences of 2, 4, and 5%, respectively; in the same samples, under cold chamber conditions, the final incidences were 25, 30 and 58%. A linear relationship was obtained between the incidences of F. moniliforme in the seeds as a function of the storage, with R² > 0,90 when the seeds were stored in an uncontrolled ambient.
