Even if it could be considered a secondary crop from the agriculture economy point of view, blackberries could have an important role in the health balance of peoples who suffer of some anemias or of those who have different cardiovascular affections, some intestinal affections or even some intoxications. This is because blackberries contain important amounts of vitamins, microelements and very important, serious amounts of antioxidant substances but in the same time, this fruits have a very low caloric content. Dried fruits and leaves could be used for aromatic tea, with high content in antioxidant substances. Blackberry plantations pathogens have obviously their origins on blackberry plants from wild flora. This is the reason why we bring on attention the infectious pressure of some of the most important blackberry’s pathogens, the fruits grey mold produced by fungus Botrytis cinerea and the leaf rust produced by fungus Phragmidium violaceum. Generaly speaking the Rubus species of blackberry from wild flora are very tolerant to this pathogens, but when we take in consideration the possibility of severe infections on blackberry plantation where are used varieties and hybrids of Rubus fructicosus L. It is in our interest to observe that this species have a lot of relatives in wild flora, as there are Rubus sulcatus, Rubus procerus, Rubus banaticus, Rubus thyrsanthus, Rubus argenteus, Rubus tomentosa, Rubus hirtus and Rubus caesius. From this point of view it is important that all these species could be infected by both fungi and so they contribute to the infectious pressure, which have effects also on cultivated blackberry from different plantations. In the present paper are presented data concerning both pathogen agents in the area of Nera Canyon National Park. Results of this analyze have extremely importance on the epidemiology model of some cultivated plants pathogens which have relative host species on wild flora.
