Der Einsatz von Sortenmischungen zur Reduzierung des Krankheitsbefalls und zur Ertragsstabilisierung bei Sommergerste

Introducing varietal mixtures to reduce mildew attacks and to stabilize yields in spring barley Cultivation of varietal mixtures of spring barley aims at producing a growing crop resistant to barley mildew ( Erysiphe graminis DC. f. sp. hordei Marchal). The so far rather short life of current varieties showing vertical resistance should be prolonged by using mixtures of several varieties. By using varietal mixtures, stabilization of crop yields is obtained due to the decrease of mildew‐related variability range of spring barley yields. Furthermore, labour and material are saved by reducing, or omitting, fungicide application.
