Tamm, Lucius; Amsler, Thomas; Schärer, Hansjakob and Refardt, Matthias (2006) Efficacy of Armicarb (potassium bicarbonate) against scab and sooty blotch on apples. In: Boos, Markus (Ed.) ecofruit - 12th International Conference on Cultivation Technique and Phytopathological Problems in Organic Fruit-Growing: Proceedings to the Conference from 31st January to 2nd February 2006 at Weinsberg/Germany, Fördergemeinschaft Ökologischer Obstbau e.V.

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 protection agents to a very large extent.
