Kresoxim-methyl is a strobilurin fungicide.1 It inhibits conidial germination of V. inaequalis isolates from apple orchards (EC50s = 0.00033-0.0078 mg/L). Kresoxim-methyl 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-methyl is toxic to goldfish (C. auratus; LC50 = 0.807 mg/L).2
