An experiment was conducted with the objective to determine the survival period of Mycosphaerella fijiensis on common long distance dispersal materials: iron, wood, plastic, cotton textiles, fruits and leaves of banana (Musa sp.), rubber (tires) and cardboard packing. Conidia of M. fijiensis produced on PDA were atomized onto materials. The infested materials were placed in rooms with and without air conditioning systems and in a shed. Conidium survival was evaluated zero, one, three, five, seven, ten, 13, 18, 23, 30 and 60 days after infestation by collecting conidia, plating them and incubating at 25 ºC. Conidium germination was quantified by microscope 24 h after incubation. The results showed that the conidia remained viable on leaves and cotton textiles until the last evaluation. The viability of M. fijiensis on cardboard, wood, plastic and tires surfaces was detected up to 30 days after infestation. On fruits and iron, conidia remained viable until 18 days and ten days after infestation, respectively.
