Notes: Cymoxanil-d3 is intended for use as an internal standard for the quantification of cymoxanil (Item No. 24232) by GC- or LC-MS. Cymoxanil is a cyanoacetamide fungicide.{43132,43136} It inhibits the mycelial growth of 12 isolates of P. infestans with EC50 values of 0.27-0.57 μg/ml.{43133} Cymoxanil (5-100 mg/L) inhibits the growth of several strains of S. cerevisiae (IC50s = 8-25 mg/L) but not S. pombe, K. marxianus, P. anomala, or C. utilis.{43134} A spray application of cymoxanil (1 mg/ml) one day after inoculation of potato leaves with P. infestans and cucumber leaves with P. cubensis reduces blighted leaves by 79 and 60%, respectively.{43132} It is toxic to rats with an acute LD50 value of 3.8 mmol/kg.{43135} Formulations containing cymoxanil have been used to prevent fungal growth on crops and treat late potato blight in agriculture.
