How is my sycamore tree suffering? - Common diseases at a glance
As its profile tells us, Eschenahorn is one of the non-native maple species. Accordingly, an Acer negundo is vulnerable to European plant diseases. Typical symptoms of frequent infections with tips for combating this guidebook illuminated in a practical and comprehensible manner.
White-gray fluff on the foliage signals fungal infestation
What a fright, when the distinctive pinnate leaves on the ash maple are covered with a whitish gray coating. If the fluff can be wiped off with your fingers, there is no longer any doubt as to the cause of the problem. Powdery mildew is one of the most common diseases that can be complained of on the Acer negundo and its beautiful varieties. How to combat the fungal infection:
Treat the whole tree with the milk water two to three times a week. In the early stages, the home remedy has been well proven to effectively combat powdery mildew.
Maple ruffle scab speaks also American
Its North American origin does not save the Eschenahorn from a widespread maple disease. The symptoms look more dramatic than the disease actually is. How to recognize the infestation and react correctly:
The cause of the tar blight, as is often called maple ruffle scab, are fungal spores from the group of ascomycetes. Since the pathogens can only reproduce on the fallen foliage, you can prevent a renewed infestation with a simple measure. Collect and destroy all leaves, disrupt the development cycle and save your sycamore in the coming year.
Tips
There is little hope for an ash-tree maple, in places where leaves and shoots wither, while neighboring regions of the crown appear healthy. This symptom is typical of the dreaded Verticillium wilt. The fungal pathogens infest the tree from the roots and clog the supply lanes. The subsequent infirmity is stopped by any known fungicides.
