Özet: Cultivated oat (Avena sativa L. and Avena byzantina Coch ) is used in human and animal feed and the most produced cereal after corn, wheat, barley, rice and millet in the world. Oat crown rust (Puccinia coronata f. sp. avenae) is the most common and harmful disease of oats. It is named as crown rust due to image of the teliospores’ tips under the microscope that resembles the shape of the crown. Oat crown rust (Puccinia coronata f. sp. avenae) is epidemic in oat (Avena spp.) growing areas in the world, except in arid regions, causing yield losses from 10% to 40% and may cause significant yield and quality losses in susceptible cultivars in terms of severe infections. In the control of oat crown rust (Puccinia coronata f. sp. avenae), early sowing, avoiding high sowing rates (using the appropriate sowing norm), non-excessive nitrogen fertilization, removing plant residues, using resistant varieties and fungicide applications are recommended. Due to the life cycle of sexual and asexual reproduction of the agent, the emergence of new crown rust races in terms of virulence and aggressiveness in different periods affects the success of the existing sources of resistance to the disease negatively. In our country, studies on oat crown rust (Puccinia coronata f. sp. avenae) are limited. With this review, it is aimed to provide information on the geographical distribution, economic importance, biology, symptoms, harm, host and control of the oat crown rust (Puccinia coronata f. sp. avenae), which is considered the most important and destructive disease of oats. Suggestions for what to do against the disease are presented.
