Acer campestre

Field Maple

Aceraceae

Mildew (Uncinula bicornis):

Flour rope (Uncinula bicornis): grey-white coat with the finger wipe offable. Does not have to be treated. Remove strong infestation leaves in the autumn.

Diseases Acer campestre

Leaf marks (Didymosporina aceris):

Only small black marks on the sheets. Later larger brown marks up to the sheet waste. Treatment not necessarily.

Cancer (Nectria galligena):

Fungal attack breaks open the bark. Stricken branches should be removed and burned. If the trunk is stricken the cancer should be cut out by a specialist.

Plant Louse (Periphyllus villosus)

Leaf changes by plant louse parasitic growth. Harmless for the tree.

Verticillium (Verticillium alboatrum)

Tracheomykose (parasitic fungus illness) far spreads in gardening used soils. The fungus penetrates over the roots and clogs the line courses (brown colouring). The leaves wither. Also only parts of the tree can be concerned. An exact evaluation should make the specialist, since withered features also can have different causes (root damage, dryness etc.).
