Rhynchosporium secalis on rye

Rhynchosporium secalis is a species of ascomycetes ( Ascomycota ) from the class of Helotiales. Rhynchosporium secalis is the trigger of Rhynchosporium leaf blotch of barley, rye and triticale. This is expressed in spindle-shaped, blue-green, but quickly gray white discoloring spots of up to 2 cm in size. This leads to yellowing and death of the whole leaf. The spores are spread through raindrops. Through this form of distribution the Rhynchosporium leaf blotch is relatively location- bound, and the infestation occurs initially on nests example. The greatest economic damage they caused in barley.
