Occurrence of necrotrophic leaf pathogens in wheat and their relation to symptom development in Hungary (2000-2002)
1879-2720 leaf samples from 8-13 stations of Hungary were collected in March, April, May and June 2000-2002. Drechslera tritici-repentis, Septoria tritici, Stagonospora nodorum and Bipolaris sorokiniana were found in the leaf samples. The occurrence of necrotrophic pathogens was highest (10,79%) in...
