Auftreten der Blattdürre an Winterweizen (Drechslera tritici-repentis) in Abhängigkeit von der Fruchtfolge und unter dem Einfluß verschiedener Spritzfolge

Incidence of yellow leaf blotch (Drechslera tritici-repentis) on winter wheat in dependence on crop rotation and under the influence of different spray programs On winter wheat grown on two experimental fields in different crop rotation programs, a severe incidence of Drechslera tritici-repentis on the leaves was observed. Monoculture of wheat resulted in a significantly higher attack than growing in rotation with other crops. A distinct relation between different spray programs and disease severity could be found only in isolated cases.
