Common diseases on maple tree - symptoms and control
From tree diseases a maple is not spared. Treacherous pathogens target the beautiful leaves, the distinctive bark or the shoots. Concerned gardeners are not powerless against the damage. This guide identifies typical symptoms and natural control methods. This will scare off common tree diseases on the maple.
Maple ruffle scab - recognize and treat signs
One of the most common tree diseases on the maple is aptly named after the tree. The pathogens of Ahornrunzelschorf have specialized in the genus. Due to the unmistakable damage pattern, the infection is also referred to as tar blight disease. How to Diagnose and Fight Fungal Infection:
By interrupting the developmental cycle of the fungal spores by carefully removing the leaves, your maple tree will be spared the disease the following year.
Identify and combat red-fungal fungi - this is how it works
The unmistakable fruiting bodies reveal one of the most common tree diseases only in autumn and winter. Long before, the pathogens of red pustule disease have taken root in a weakened by errors in care maple tree. How to get the fungal spores on the track:
Compared to known fungicides, the pathogens have so far proved to be resistant. In field trials, experts in tree diseases found that cutting back into healthy wood deprives the fungal spores of their livelihoods. The best time for the action is on a mild, dry day between early September and mid-October.
Verticillium wilt - recognize symptoms and act right
For the fungi of the genus Verticillium a maple is the most important host plant. Unfortunately, the pathogens invade the pathways across the ground, blocking the supply of water and nutrients, causing the affected maple tree to doom. Since the disease is massively contagious, we recommend immediate grubbing and subsequent soil replacement. From these symptoms you recognize the Verticillium wilt:
Typical of the Verticillium wilt is the partial occurrence of these symptoms. While there are no signs in one region of the crown, other areas are gradually dying out. Based on this localized spread, the disease can be easily distinguished from frost damage, drought stress or waterlogging.
Tips
If brown leaves on the maple tree are a concern, it is usually not a disease. If the brown discoloration on the leaf margins begins, the tree or shrub suffers from a site problem or care failure. A wind umtoster site triggers the damage as often as too wet or too dry substrate.
