Common sycamore diseases - Tips for fighting
Its monumental shape and robust physique do not protect the sycamore from infection. Although most diseases do not destroy the beautiful deciduous tree, they still disfigure its magnificent foliage or decorative shoots. Reason enough to familiarize yourself here with typical symptoms and proven methods of combating common diseases.
Detecting and preventing tar blight - That's how it works
The fungal infection tar-stain disease is also known under the name Ahornrunzelschorf. The pathogen Rhytisma punctatum has specialized in the sycamore maple. Visible symptom of the attack are black spots with pale yellow margin on the leaves. Heavily affected leaves become brown and fall prematurely.
You do not need to resort to chemical sprays to combat it. By removing all leaves in the fall, you interrupt the development cycle of the pathogen so that there are no further infections. Incidentally, this strategy has proven well in other fungal infections of maple species.
It is important to note that you do not dispose of the foliage on the compost. From here the mushroom spores find their way to their sycamore maple again. Put the leaves in the household waste or bury them at least 20 cm deep in the ground.
Red pustule disease - symptoms and control
Red ostrich disease (Nectria cinnabarina) is one of the most common shoot and bark diseases on the sycamore maple. How to recognize and fight the infection:
In field tests, experts found that sprayings with fungicides did not produce a noticeable control result. The most effective method of prevention is to avoid stress factors of all kinds, as the pathogens have specifically targeted weakened sycamore trees.
Verticillium wilt leaves no chance for sycamore
The only sycamore disease with no options for control is expressed as wilted, pale green leaves. The soil-borne pathogen successively clogs all the pathways in the tree, so that ultimately it is damned to die. So that the fungus does not spread further in the garden, we recommend the timely clearing of the affected maple.
