Like other areas in high hill areas, where traditional agricultural crops do not work, there is a possibility of focusing on plants that are highly adapted to the area and can bring satisfactory economic results. An example of such plants is raspberry, which could be easy adapted on areas like those found in the valleys of the main rivers in Caraş Severin County. One of the most important conditions for the success of such a culture is to have previously the knowledge of the potential technological problems which could impede the development of plants and the yield quantity and quality. One of these problems, which is very difficult to avoid, is the pathogens presence on raspberry plants from the spontaneous flora of these areas because in favorable conditions these pathogens could produce significant yield loses. Present paper contain data about evaluation of a well-known disease such as the gray rot of fruit produced by the Botrytis cinerea on raspberry plants from spontaneous flora. These pathogen produce random attacks on a few Rosaceae species such as Rubus sp., Fragaria vesca and Rosa canina. This fact leads to a high probability of pathogen disamination from the spontaneous flora natural reserve to any other raspberry culture, blackberry culture or even rose culture from the reference area. The area where observations were made is located in the middle basin of the Nera River, a well-known area for the high diversity of flora species, including species from Rosaceae genus. All data were collected during years 2016 and 2017 from raspberry populations (Rubus idaeus), large enough to be representative for this area and for statistical computation. Regarding to methodology, the main steps were: first step to identify pathogens, the second step was to record primary data of the pathogen attack frequency and intensity and the last step was the statistical evaluation of field data. The results confirmed a relatively constant presence of Botrytis cinerea fungus in raspberry in the middle basin of the Nera River.
