Fungicide Resistance Action Commitee

Carboxylic Acid Amides (CAA) Fungicides

NA-CAA working group of FRAC

The NA-CAA working group of the North American Fungicide Resistance Action Committee (NA-FRAC) was first established in 2007. The main goal is to maintain a great level of harmonization of resistance management guidelines. The risk of risk of resistance for this group of fungicides is considered low to medium depending of the pathogen. The development of resistance in Phytophthora is considered low. In downy mildew pathogens resistance development is considered of medium risk. The companies currently involve in the NA-AP group are BASF and Syngenta.
