Oats (Avena sativa L.) currently rank sixth in world cereal production after corn, rice, wheat, barley and sorghum. In 2021, the area cultivated with oats in Romania was 87000 ha, and the average production was 2413.8 kg/ha. The importance of oats is given by its many uses in animal husbandry, human nutrition, beer production, in the cosmetic and pharmaceutical industry, etc. In the present work they are presented the symptoms that manifested the infection with the fungus Puccinia coronata (Corda); the morphological characters of the uredospores, the spores that ensure the propagation (spread) of the disease in culture, and of the teliospores, the resistance spores through which the disease spreads over time (transmission), from one year to another; the effectiveness of tested fungicides whose active substances contain: prothioconazole 53 g/l + spiroxamine 224 g/l + tebuconazole 148 g/l; 100 g/l mefentrifluconazole+300 g/l metrafenone. The research focused on the Ovidiu variety and was carried out under natural infection conditions, during the vegetation period of 2021 in Mircea Vodă commune, Brăila county. The effectiveness of the fungicide treatments applied to the oat crop was reflected in a production increase between 265 and 365 kg/ha.
