Fungicide Resistance Action Committee
Search

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.

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:

    • Apply CAA fungicides always at recommended dose rates
    • Apply CAA fungicides using not more than 2 consecutive applications
    • Apply CAA fungicides preferably in mixtures with effective partners belonging to different modes of action
    • An effective partner for a CAA fungicide is one that provides satisfactory disease control when used alone at the mixture rate
    • Good agricultural practices must be considered to reduce source of inoculum, disease pressure and resistance risk, e.g. consider to plant resistant varieties and refer to disease prediction models

    In regions with reported cases of resistance:

    • CAA fungicides must be used in mixtures, with not more than 2 consecutive applications
    • In case mixtures cannot be applied for regulatory reasons, apply CAA fungicide in strict alternation
