The aime of our research was to detect diseases and the effectiveness of some treatments on two-row barley during 2021-2023, in the Murighiol location, Tulcea County. The biological material was represented by the Romaniţa spring two-row barley variety. The experiment monitored the attack in treated and control variants. The analyzed pathogens were Blumeria graminis f. sp. hordei, the powdery mildew pathogen, Pyrenophora teres, the net blotch pathogen and Rynchosporium secalis, responsible for the appearance of rhynchosporiosis. The lowest values of the powdery mildew attack in the control variant were recorded in 2023, with values of the degree of attack of 14.9% and 23.5% in 2022. The application of treatments reduced the attack and had an effectiveness of over 73% in controlling powdery mildew during the analyzed period, around 71% in 2022 and 75% in 2023 in controlling net blotch. The rhynchosporiosis attack was sub-unitary.
