Conteúdo: 	Storage decay is the primary cause of postharvest losses in integrated apple production worldwide. At harvest, fruit can appear free from infection but develop symptoms later during long-term storage, making treatment and prediction of fungal growth during storage challenging. Therefore, this study was conducted to observe the etiology of fungal decay symptoms during storage under a controlled atmosphere (CA). Commercial data of disease incidences over 17-years were collated and analyzed. ?Fuji? and ?Gala? fruit were grown between 2002 and 2018 in commercial orchards in southern Brazil. The orchards represented a ?warm? growing site with a low altitude and a ?cold? growing site with a higher altitude. Decay incidences were performed every month for eight months. Results showed that total disease incidence increased as the storage duration increased. Storage decay was primarily caused by Neofabraea spp. (bull?s eye), followed by Penicillium spp. (blue mold) and Botrytis spp. (gray mold). ?Fuji? apples had higher incidences of decay during CA-storage than ?Gala? due to higher incidences of Alternaria spp. and Fusarium spp. (moldy core rot). For both cultivars, fruit from the warm site had higher incidences of bull?s eye rot than the cold site. For ?Fuji?, fruit from the warm site had higher incidences of moldy core rot than the cold site. There was an increasing trend in disease incidence for both cultivars and growing sites over the 17-year study. However, the yearly increase in disease incidence was more prominent for the ?warm? site. For both locations, high incidences of storage rot occurred when high average temperatures occurred concurrently with high annual rainfall.
