Fungicide Resistance Action Committee

Anilinopyrimidines (AP) Fungicides

NA-AP working group of FRAC

The NA-AP working group of the North American Fungicide Resistance Action Committee (NA-FRAC) was established in 2005. The NA-AP group provides a strong local voice for the AP group in the region and push for the right implementation of agreed strategies into the market place. The NA-AP group functions as a local working group of FRAC international and focus in the publication of the guidelines and education of growers. The risk for resistance development to this group of fungicides is medium and the implementation of resistance management is required. The companies currently involve in the NA-AP group are Bayer Crop Sciences and Syngenta.
