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.
