captan phthalamide (M4) contact multi-site low highly toxic to honey bee larvae
chlorothalonil (Bravo/Echo) aromatic nitrile (M5) contact multi-site low  
fenarimol (Rubigan) DMI2-triazole (3) systemic (local) single-site high  
fenbuconazole (Indar) DMI2-triazole (3) systemic (local) single-site high  
fenhexamid (Elevate) hydroxyanilide (17) contact single-site high  
fosetyl-al (Aliette) — systemic — —  
iprodione (Rovral) dicarboximide (2) systemic (local) multi-site low  
mefenoxam (Ridomil Gold) acylalanine (4) systemic single-site high  
myclobutanil (Rally) DMI2-triazole (3) systemic (local) single-site high  
propiconazole (Bumper/Orbit) DMI2-triazole (3) systemic (local) single-site high  
Quinoxyfen (Quintec) quinoline (13) — — medium  
sulfur inorganic (M2) contact multi-site low highly toxic to native strains of western predatory mite (Galendromus occidentalis) and to parasites
tebuconazole (Elite) DMI2-triazole (3) systemic (local) single-site high  
thiophanate-methyl (Topsin-M) benzimidazole (1) systemic (local) single-site very high  
triflumizole (Procure) DMI2-imidazole (3) systemic (local) single-site high  
1 Group numbers are assigned by the Fungicide Resistance Action Committee (FRAC) according to different modes of actions. Fungicides with a different group number are suitable to alternate in a resistance management program. For more information, see http://www.frac.info/.
