Background
Difenoconazole-d6 is intended for use as an internal standard for the quantification of difenoconazole by GC- or LC-MS. 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.1,2 It inhibits the growth of F. graminearum isolates in vitro (EC50s = 1.69-19.6 mg/L for mycelial growth).2 It also inhibits growth of A. sonali, F. fulva, B. cinerea, and R. solani (EC50s = 0.131, 0.069, 0.297, and 0.252 mg/L, respectively).3 Difenoconazole reduces germtube growth of A. caricae, the mold responsible for black spot in papaya plants (EC50 = 2 ppm).4 It exhibits acute aquatic toxicity, reducing growth of S. obliquus algae (EC50 = 1.338 μg/ml) and decreasing survival of D. magna (LD50 = 0.298 μg/ml).3 Difenoconazole is also lethal to zebrafish (D. rerio) embryos, larvae, and adults (LC50s = 2.34, 1.17, and 1.45 mg/L, respectively).5 At sub-LC50 concentrations, difenoconazole induces pericardial and yolk sac edema in zebrafish embryos, body blackening and slowed heart rate in larvae, and decreased body weight and length in adults.
