  • Difenoconazole is a broad-spectrum triazole fungicide that inhibits ergosterol biosynthesis via inhibition of the cytochrome P450-dependent 14α-demethylation of lanosterol, which results in disruption of the fungal cell membrane and cell death. Difenoconazole inhibits the growth of F. graminearum isolates in vitro (EC50s = 1.69-19.6 mg/L for mycelial growth). Difenoconazole also inhibits growth of A. sonali, F. fulva, B. cinerea, and R. solani (EC50s = 0.131 mg/L, 0.069 mg/L, 0.297 mg/L, and 0.252 mg/L, respectively).
