Die Überwinterung des Erregers der Bitterfäule

Summary

The cycle assuring infection of the fungusGlœosporium fructigenum Berk. causing bitter-rot of cherries, rarely of apples and plums in Switzerland, is herewith discussed. The buds' raments on cherry-trees are discovered as new part of the cycle; the fungus can pass the winter in them as a parasit, just as it does in twigs. Probably the fungus begins to spread from the buds' raments in the following year.
