Summary of annual Sensitivity Monitoring

In order to generate recommendations for fungicide resistance management, the member companies of FRAC share sensitivity monitoring data. This process is done under strict anti-trust guidelines. The summary of the Sensitivity Monitoring as well as the resulting FRAC Recommendations for Fungicide Resistance Management are published annually in Minutes of the Working Group meetings, which are publically available for download:
