Research aim of the present paper is to present the dynamic of main foliar diseases of wheat caused by the fungus Erysiphe graminis and Septoria tritici. The biologic material consist from an assortment of three of the most used wheat cultivars from the area. Technology used in the experimental field was the standard applied for this location. The experience was implemented on the soil and climatic conditions from Didactic Station.  Last three years bring a very significant change of the main climatic factors (temperature and rain water) with a direct influence in dynamic of majority of diseases caused by fungus and bacteria. Taking all this in consideration we are revealing in the present paper the behavior of three from the most important cultivars from the Western Plain at the attack of both funguses under the last three years climatic changes. The experience was calculated after normal statistic method for bifactorial experiences, with first factor the cultivar and the second factor the observation year. The achievements bring by the present work consist from the first author experience in research of the wheat diseases and also the possible reactions of the pathogen relating to local biocoenosis factors. Limits of the research are that data refer strictly to the relation between cultivars and pathogens. Practical implications of the research are that all data presented in the present paper are a part of a complex study of wheat diseases protection strategy. This strategz is important for the both funguses, Erysiphe graminis and Septoria tritici because they can be considered as endemic disesas for wheat in the Western Plain of Romania. The originality of the work comes from the fact that data are relevant in view of cultivars behaviour under specific conditions. The relevant data, experimental results give an overview of pathogen behavior in relation to experimental conditions.
