Common leaf spot of alfalfa is one of the most important diseases of alfalfa that primarily affects the foliage of plants. Our research followed the influence of the attack of this disease on the mineral content of the plants affected by the attack of the micromycete Pseudopeziza medicaginis f.sp. medicaginis-sativae to the causative agent of common leaf spot of lucerne. Samples were made with plants free from the pathogen and with characteristic attack and the concentration was determined (g per 100g dry plant). The attack of the fungus Pseudopeziza medicaginis f. sp. medicaginis-sativae (Schmiedeknecht) Schmiedeknecht influenced the concentration of micro and macronutrients in alfalfa. For some elements (Cd, Co, Ga, In, Pb) the concentration values were below the detection limit of the method.
