Christy mentions at some point "What the frick is a FRAC?" Here is a quick run down of the products and their FRAC codes from Christy's most recent trial in 2020.  "Always be rotating through them and guard the 7's with your life".

Viathon = tebuconazole + potassium phosphite = FRAC 3 + 33
Luna Experience = fluopyram + tebuconazole = FRAC 7 + 3
Luna Tranquility = fluopyram + pyrimethanil = FRAC 7 + 9
Inspire Super = difenoconazole + cyprodinil = FRAC 3 + 9
Quadris Top = difenoconazole + azoxystrobin = FRAC 3 + 11
Merivon = fluxapyroxad + pyraclostrobin = FRAC 7 + 11
Rovral = iprodione = FRAC 2
Scala = pyrimethanil = FRAC 9
Endura = boscalid = FRAC 7
Cabrio = pyraclostrobin = FRAC 11
Quadris = azoxystrobin = FRAC 11
