WARNING
Demethylation Inhibitor (DMI)
Inhibits sterol 14α-demethylase (CYP51), blocking the conversion of lanosterol to ergosterol in the fungal cell membrane synthesis pathway. Triadimefon is one of the earliest triazole fungicides registered for turfgrass and remains effective when used as part of a rotation program.
Rate Range
0.5 – 1.0
fl oz / 1,000 sq ft
Interval

Medium resistance risk. Reduced sensitivity to triadimefon has been widely reported in dollar spot populations — often cross-resistant with other DMI fungicides. Use in rotation with non-FRAC 3 products and monitor efficacy closely.
