Diseases |
|
Field Marpel
|
| |
 |
| 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. |
|
| |
 |
| 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.). |
