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.
