Physiological problems, Lack of diseases

Chlorosis:
Occurring during the main growing period of the vine Chlorosis (bad weather, compaction and Weakness, chlorosis) are mainly due to soil compaction causes. The most important causative factor is too high a soil water content. By the early Sowing of oil radish per 250 g Are the water content the substrate can be reduced. At the same time By this measure, a long-term structural improvement achieved in the underground.

Potassium deficiency:
Sometimes occurs after break-in of skimmed reported. A Fertilization with potash, combined with deep-rooted seeding, leads to long-term remedy. Leaf spraying with 0.5% Kalisulfatlösung help in the short term.


Magnesium deficiency:
Earlier autumn coloration, caused by magnesium deficiency, may the next year by adding 1% Epsom salts (magnesium sulfate) prevented the fungicide sprayings.

Stem paralysis:
The exact cause paralysis of the stem is not yet known. The stem paralysis may be the result of many diseases that attack the stem structure. The berries are separated by the slack of the stems of the water supply and not to intervene.

Are considered susceptible stem crippling varieties: Riesling Silvaner u, Chasselas white and red, Gewurztraminer and Räuschling.

The varieties Pinot Noir, with the exception of Mary-box clones is generally less susceptible, so that usually a Stem paralysis treatment can be omitted.

Seeding, permanent green cover reduce nitrogen fertilizer and reduced the Occurrence of stem paralysis rich, but as a preventive Measures in years with high expectations, did not attack to prevent from, to yield and quality losses.
