Kresoxim-methyl-d7

Kresoxim-metl-d₇ is intended for use as an internal standard for the quantification of kresoxim-metl by GC- or LC-MS. Kresoxim-metl is a strobilurin fungicide.¹ It inhibits conidial germination of V. inaequalis isolates from apple orchards (EC₅₀s = 0.00033-0.0078 mg/L). Kresoxim-metl also inhibits mycelial growth (EC₅₀ = 0.240 mg/L) and is fungicidal against Saprolegnia (MIC = 1 mg/L).² It increases intracellular calcium levels and disrupts the mitochondrial membrane potential in mouse cortical cultures in a concentration-dependent manner.³ Kresoxim-metl is toxic to goldfish (C. auratus; LC₅₀ = 0.807 mg/L).² Formulations containing kresoxim-metl have been used in the control of fungi in agriculture.
