 | Heavy rainfall in spring with mild temperatures favour the spread of this common species, the spores of which develop quickly in these conditions to infect further leaves. Leaves shed in summer are replaced in the same year by a second generation. This disease is commonly not dangerous for the planes, only very young plants might suffer. Further information (in German): Gehölzkrankheiten in Wort und Bild (TUM Weihenstephan).
Curative measures Removal of the litter in autumn (only if young trees are infected), since the fungus there hibernates in its sexual stage.
