The paper aimed to present the main pathogens of wheat, barley and two-rowed barley crops and the yields obtained in2014 at S.C. SPORT AGRA SRL Amzacea, Constanta district on demonstrative plots. Climatic conditions of autumn2013 and spring 2014 provided a favorable development of small grains studied. Protection against foliar diseases ofthe three cereal crops was done using three treatments with Bumper 250 EC, Artea 330 EC and Prosaro 250 ECfungicides, no attack of powdery mildew (Blumeria graminis) was registered. The attack of Rhyncosporium secalis andPyrenophora tritici-repentis in barley and two-rowed barley presented a low level, except the Casanova barley variety(10.8%). On wheat, the pathogens Septoria tritici and Pyrenophora tritici-repentis had low attack levels, except thecultivars Akratos, Renan, Jinda, Epos and Evina with higher attack. The pathogen Puccinia striiformis had the lowestvalues of attack, except the variety Andelka (5%). Concerning the correlation between the yields and the pathogensincidence and severity, the lowest yields in wheat crop were obtained with Arkeos (4250 kg/ha) and Renan varieties(4300 kg/ha). The highest yields were obtained with Ingenio (7600 kg/ha) and Katarina varieties (7930 kg/ha). Forbarley crop, the lowest yield was 5858 kg/ha for Gerlach and Casanova varieties and the best yields were 7500 kg/hafor Kendy variety and 8000 kg/ha for Laverda variety. To the two-rowed barley crops, the yields were between5600 kg/ha for Trasco variety and 6200 kg/ha for Metaxa variety. Quality indices of wheat grains were between 72 and78.7% hectoliter mass.
