WHAT IS ARMICARB®?
Armicarb® is a specially optimised formulation of potassium bicarbonate for use against target diseases in agriculture and horticulture.
Effective against a broad range of diseases in pome fruit, stone fruit, soft fruit, grapevines, hops, vegetables and ornamentals.
Included in Annex I to Directive 91/414/EEC, Armicarb® is exempt from EU MRLs, and authorised for use in organic production by the European Commission.
Armicarb® is a soluble powder containing 85 % (w/w) potassium bicarbonate.
Armicarb® is especially suitable for use in programmes with conventional fungicides, as well as in organic fruit, wine and vegetable production.
HOW DOES ARMICARB® WORK?
Armicarb® has a multi-site mode of action, acting through a combination of osmotic pressure, pH, and specific bicarbonate/carbonate ion effects.
By consequence, the risk of resistance developing is considered to be low, and according to the Fungicide Resistance Action Committee (www.frac.info) no resistance is known. Armicarb® acts very rapidly to cause dehydration and total collapse of spores and mycelium of susceptible fungi (see photographs below, courtesy of Dr. Ken Horst, H&I Agritech, Inc.).

ARMICARB® HIGH-TECH FORMULATION
Armicarb®’s proprietary wetting system ensures a complete and thorough coverage of plant surfaces, whilst at the same time limiting wash-off of the highly water-soluble active substance by rain.
It is this critical balance of ‘sticking’ and ‘spreading’ by the formulation that delivers a level of field performance, outdoors as well as in protected conditions, equivalent to conventional fungicide standards.
ARMICARB® USES
Armicarb® provides good levels of control of many economically important fungal diseases, including apple scab, Botrytis cinerea and powdery mildew in grapevines, and powdery mildew in soft fruit and vegetables.
