Brown spot is a fairly common disease in quinces and pear trees in the area where the observations were made. As with other pathogens in fruit trees, in order to maintain the level of losses produced by this pathogen at an acceptable level, it is mandatory to know the level of its infectious load in the reference area. To achieve this goal, determinations of the attack parameters for fungus Entomosporium maculatum were performed. All measurements were performed on groups of trees located in locations located in significant areas as location both in distance in space and in terms of altitude. This makes possible an objective determination of the infectious pressure, taking into account the most common climatic and soil conditions in the reference area. 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 interval 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 Greoni commune, the second location around Răcășdia commune, the third location near Cărbunari commune and the fourth location near the town of Anina.
