The objective of the present study was to evaluate the effects of CPPU (N-2-cloro-4-piridil)-N-phenylurea), Promalin (GA4+7 + BA), Benzyladenine (BA) and Thidiazuron, sprayed on "Fuji" apple trees at full bloom stage, on the incidence of moldy core, in the 2001/2002 and 2002/2003 seasons. The experimental area was a Fuji/EM-9 apple orchard, established in 1994 in Vacaria / RS. The apples were evaluated for fruit shape and moldy core incidence. During 2001, the seeds of carpel of apples treated with Thidiazuron and Promalin showed more fungi colonization than the control fruit. There were significant differences between treatments on moldy core rot incidence as well as in preharvest dropped apples and in apples evaluated after three months of cold storage, during the two evaluation seasons.
