Fungicide Resistance Action Committee

Welcome to FRAC

Fungicides have become an integral part of efficient food production. The loss of a fungicide to agriculture through resistance is a problem that affects us all. FRAC works to prolong the effectiveness of fungicides liable to encounter resistance problems and to limit crop losses should resistance occur.

FRAC Resources

Communication and education is key to promoting awareness on fungicide resistance and effective resistance management strategies worldwide. FRAC has published a wide range of communication and educational material, all of which are available for free to download from the website:

    Minutes and recommendations of the OSBPI Working Group are now available

    Summary of monitoring-data from 2019 for OSBPIs is given the minutes: Link

    The recommendations for all other crops than Grapes were changed as follows (changes in bold):

    • Make no more than four (4) applications or maximum 33% of the total period of protection needed per crop, whichever is more restrictive.
    • Where the total number of fungicide applications targeting oomycetes is less than three (3), apply no more than one (1) application of an OSBPI product.
    • There should be no more than two (2) foliar applications of any OSBPI product for the control of soil-borne pathogens.
    • Applications of OSBPI-containing products are to be made no more than three (3) times in sequence before applying a fungicide with a different mode of action. In areas where the agronomic risk is very high (e.g. continuous potato or cucurbit cropping) and resistance has already been reported, further restrictions to the number of consecutive applications are recommended.
    •  Applications of OSBPI products can be made in alternation with a fungicide with a different mode of action.

    No further changes were made based on the monitoring to the other OSBPI WG recommendations for 2020 to 2021 (link) compared to the previous year.
