| A novel formulation of potassium bicarbonate (Armicarb) was evaluated in 2004 and 2005 as agent against apple scab (3 field trials) and sooty blotch (2 field trials). Armicarb controlled scab equally well as the reference treatments sulphur and copper. Armicarb showed also excellent activity against sooty blotch. However, potential side-effects such as lenticell spot development need further investigation. At present, potassium bicarbonate is considered by the Swiss registration authorities as non-toxic to humans and in consequence, no residue levels have been specified. Armicarb has very interesting properties as a plant protection agent and its composition and risk profile are expected to fulfil the IFOAM standards for acceptance of novel plant... |

| A novel formulation of potassium bicarbon-ate (Armicarb) was evaluated in 2004 and 2005 as agent against apple scab and sooty blotch in several field trials. Armicarb controlled scab equally well as the reference treatments sulphur and copper. Armi-carb showed also excellent activity against sooty blotch. However, potential side-effects such as lenti-cell spot development need further investigation.

| Novel organic fungicides and elicitors against downy mildew on grapevines were evaluated on grapevine seedlings in a series of indoor screening experiments under controlled conditions and, if they have shown a good efficacy indoors, in a screening vineyard under field conditions. From 39 products tested under controlled conditions 10 were further examined under field conditions. All of the new products tested under field conditions showed at least partial efficacy. However, the efficacy was not good enough to protect grapevine plants sufficiently from downy mildew. For a complete re-placement of copper in plant protection against downy mildew on grapevine in organic agriculture, additional new products are needed. |

| Die gezeigten Ergebnisse deuten darauf hin, dass einige interessante Alternativprodukte zu Kupfer in Entwicklung sind. Diese sind jedoch noch weit entfernt von der Marktreife. Mit den Tonerden stehen aber schon jetzt gute Alternativen zu Kupfer zur Verfügung, die uns erlauben, in normalen Jahren die Krankheitsentwicklung bei Reben zu kontrollieren. In der Schweiz sind vorerst die bekannten Alternativen mit Tonerde verfügbar. Seit 2004 ist Kaliumpermanganat neu in der Schweizer Bioverordnung aufgeführt. Kaliumpermanganat ist nicht in der FiBL-Hilfsstoffliste aufgeführt, da kein Handelsprodukt kommerzialisiert ist. Kaliumpermanganat kann aber im Handel bezogen werden. In Deutschland, Italien und Frankreich wird verschiedentlich Phosphit eingesetzt,... |

| Einleitung Das Pflanzenschutzmittel Biofa Cocana RF ist im schweizerischen Bio-Kernobstanbau das einzige zugelassene Mittel zur Bekämpfung der Regenfleckenkrankheit. Da es sich bei diesem Produkt um eine Kali-Seifenlösung handelt, besteht die Möglichkeit, dass es nach dessen Einsatz zu einer geschmacklichen Beeinträchtigung des Endproduktes Apfelsaft, bzw. Süssmost kommen könnte. Eine Untersuchung an der Hochschule Wädenswil mit Apfelsäften, denen Cocana zugesetzt wurde, kam zum Schluss, dass es einen Zusammenhang zwischen Kaliseife und Fremdgeschmack geben könnte. Um abzuklären, ob unter Praxisbedingungen eine geschmackliche Unterscheidung zwischen Saft aus mit Biofa Cocana RF behandelten Früchten und solchem ohne Einsatz des Mittels er-kannt werden... |
