The aim of the research was to monitor the attack of some pathogens specific to alfalfa crops, in the period 2020-2022, in the Murighiol area, Tulcea county. An attack was detected by Pseudopeziza medicaginis ([Lib.] Sacc), responsible for the production of common leaf spot of lucerne or leaf spot of lucerne and Peronospora trifoliorum (de Bary) f. sp. medicaginis-sativae (Thuem.), a pseudofungus that produces downy mildew of alfalfa. The leaf spotting attack was higher during the observation period, reaching 10.3% in the control variant in 2021. The downy mildew attack was lower in 2022. The application of the treatments reduced the impact of the monitored pathogens, ensuring more than 60% effectiveness in the case of the attack of downy mildew and over 70% in the case of the attack of common leaf spot.
