Distribution of pathotypes of sunflower downy mildew (Plasmopara halstedii (Farl.) Berl. et de Toni) in Hungary
Downy mildew of sunflower, caused by Plasmopara halstedii (Farl.) Berl. et de Toni, is one of the most important diseases of sunflower. There are several pathotypes of the pathogen and the number of these races is increasing rapidly. Recently, new races, such as 704 and 714 have been identified in Hungary. It is essential to regularly test the virulence pattern of this pathogen for effective resistance breeding of sunflower. Our objectives are to monitor continuously sunflower downy mildew and identify pathotypes of P. halstedii in Hungary.
