In 2017, the first year of PhD student experience, I performed evaluations of Rosaceae family plant pathogens from the spontaneous flora in the northern part of the area designated for observation. This region is situated between Minis River and Caras River in South Western Part of Romania. Blackberries are one of the Rosaceae family most often seen plants on the area. Bushes of blackberry could be found on the forests, in the areas where trees have low density or where there are gaps resulting by tree falling or cutting. Also there are regions where on the forest clearing could be found larger populations of blackberry. Due to the density of plants that make up local populations it can be appreciated that these species is well adapted to the climate and soil conditions of the area. One of the most common diseases in the soil was the rust affecting the leaves of the plants. Considering the frequency and intensity of pathogen attack, it can be said that rust is endangering the integrity of blackberry populations in the reference area. This disease start to show up on the plants leaves starting on June and finish late on the autumn, only when the vegetation time period is on the end. The pathogen involve blackberry rust is Phragmidium rubi-idaei. This pathogen affect blackberry leaves and has as major effect a premature drying of the leaves. I found the first signs of the fungus attack starting to appear on the middle of June and this pathogeny phase could prolong to the first half of July, depending on plant position reported to the sun and also a major influence is due to rainfall amount on the area. The last phase of the fungus attack is consumed, as previously I point out starting with the lastdacade of August and it is ending within the autumn when the blackberry shrubs leaves are falling.
