| Description
| - Information on disease severity assists greatly with making decisions about crop protection systems. However, there are no published long-term field trials in different locations to determine the severity of individual diseases. National trials that relate to the agronomic traits of varieties, including disease responses, are available. The current article describes the use of such data to determine disease severity based on official Czech variety trials. In total, 838 and 334 field trials of spring and winter barley, respectively, conducted from 1976 to 2005, were analysed. To compare year to year powdery mildew severity, five parameters were used. Annual disease severity in both crops differed substantially, whereas similarity of the disease severity was rare. During the last 15 years, disease severity in spring barley was stable despite a rapid increase in the area of fully resistant spring barley varieties, particularly those with the gene m/o. During the period 1976-2005, the mean disease severity in winter barley accounted for 64.1% of the mean disease severity in spring barley. The effect of deployment of the resistance genes and growing areas of winter barley on the determined disease severity was analysed. The method described here allows easy comparisons to be made of disease severity among years, locations and different crops and diseases if similar scoring scales for disease infection evaluation are used.
