Background:

Difenoconazole-d₆is 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 biosynthesisviainhibition of the cytochrome P450-dependent 14α-demethylation of lanosterol, which results in disruption of the fungal cell membrane and cell death.^1,2It inhibits the growth ofF. graminearumisolatesin vitro(EC₅₀s = 1.69-19.6 mg/L for mycelial growth).²It also inhibits growth ofA. sonali,F. fulva,B. cinerea, andR. solani(EC₅₀s = 0.131, 0.069, 0.297, and 0.252 mg/L, respectively).³Difenoconazole reduces germtube growth ofA. caricae, the mold responsible for black spot in papaya plants (EC₅₀= 2 ppm).⁴It exhibits acute aquatic toxicity, reducing growth ofS. obliquusalgae (EC₅₀= 1.338 μg/ml) and decreasing survival ofD. magna(LD₅₀= 0.298 μg/ml).³Difenoconazole is also lethal to zebrafish (D. rerio) embryos, larvae, and adults (LC₅₀s = 2.34, 1.17, and 1.45 mg/L, respectively).⁵At sub-LC₅₀concentrations, 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.
