Fusicladium dendriticum is a very common pathogen in Europe and Romania is no exception. In limiting the losses caused by this pathogen, which affects leaves, fruits and the wood of the young shoots, it is necessary to accurately assess the reserve of the pathogen in order to make decisions on the tree protection strategy. In order to assess as accurately as possible the infectious pressure of this apple pathogen for the whole area, during last three years we measured the attack degree of the pathogen on groups of apple trees located on significant locations for the limits of the observations defined area. The observations were made in the period 2018-2020, years with a few clear differences in terms of climatic factors. All determinations regarding the pathogen were performed by successive evaluation through 4 determinations during the period between June and September of each year of the time interval between 2018-2020. The locations selected for those determinations to be carried out are grouped in terms of the dominant landforms for the reference area and they are as follows: the first location in Gradinari, the second location around Răcășdia, the third location near Sasca Română and the fourth location near the town of Anina.
