Aufbau und Qualitätssicherung für Jungpflanzen für den biologischen Obst- und Rebbau Organic Eprints
Suter, Francisco; Weibel, Franco; Tschabold, Jean-Luc; Lévite, Dominique.
Organic fruit and wine producers have to use organically produced plant material if available on the market. To support and enhance this difficult production sector a project was started in 2003 funded by the Coop Naturaplan Fonds. The improvement or development of better methods for fertilization, soil management, growth regulation and plant protection are the main objectives of this project. In our trials with apple trees we found that an intensification of the nitrogen fertilization including application of foliar fertilizers did not result in a better quality of young trees. The use of the bacterial bio-fertilizer BactoFil® Professional-2 without any nitrogen fertilization increased the tree quality under our conditions. In another experiment...

Current downy mildew control strategies in Swiss organic vineyards Organic Eprints
Tamm, Lucius; Amsler, Thomas; Schaerer, Hansjakob; Lévite, Dominique; Häseli, Andreas.
The currently used downy mildew control strategies in vitis vinifera in Switzerland are based on the use of acidified clay products combined with copper and sulphur. Data from 1997-2003 show that acidified clay products are a valuable alternative to control downy mil-dew of grapevine in conditions of medium rain fall, good spray timing and with a good application tech-nique. The limits of these products show under heavy rain conditions and when there is high disease pressure.

Grundlagen für eine zukünftige EU-Regelung Organic Eprints
Schmid, Otto; Weibel, Franco; van der Meer, Markus; Lévite, Dominique; Hofmann, Uwe.
Bio-Wein im Sinne der EU-Gesetzgebung gab es bisher nicht, doch das wird sich mit der Aufnahme der Bio-Weinbereitung in die neue EU-Öko-Verordnung bald ändern. Das EU-Forschungsprojekt ORWINE lieferte hierfür wissenschaftliche Grundlagen.

Wirkung verschiedener Bodenbearbeitungssysteme in einem biologischen Weinberg des Zentralwallis Organic Eprints
Lévite, Dominique.
Schlussfolgerungen Der Versuch, der in einem Weinberg bei Siders angelegt wurde, zeigte in Abhängigkeit von der Bodenbearbeitung kleine Unterschiede bei der Mineralstoff-Ernährung und besonders beim Stickstoff. Das äusserst trockene Klima während der Vegetationsperiode 2003 hat wahrscheinlich Mineralstoffe im Boden blockiert, die normalerweise stärkere Interaktionen auf die Pflanze ausüben. Die tensiometrische TDR-Sonde hat sehr wenig reagiert, das Bodenvolumen, das in den 20 ersten Bodenzentimetern gemessen wurde, hat sehr starke Wasserverdunstungen erlitten. Die getrennte Weinbereitung zeigt bereits Unterschiede, was bestätigt, dass die Rebe relativ schnell auf das jeweilige Bodenbearbeitungssystem reagiert.
