Abstract

Incidence of wheat leaf spot pathogens in the Czech Republic.

Abstract

The occurrence of wheat leaf spot pathogens was monitored in the Czech Republic in 2000 and 2001. The samples were collected from different localities of the Czech Republic. Spectrum of fungal pathogens was determined with microscopic methods. The frequency of the pathogens was different in both years. Pyrenophora tritici-repentis was isolated most often from samples in 2000 while Mycosphaerella graminicola predominated in 2001. Didymella sp. was one of the most important pathogens in 2001. Phaeosphaeria nodorum [Leptoosphaeria nodorum] occurred very often together with Pyrenophora tritici-repentis in the samples. Ascochyta sp. was represented by comparatively few samples in both years.
