Description and Uses
Cymoxanil is a cyanoacetamide fungicide. It inhibits the mycelial growth of 12 isolates of P. infestans with EC50 values of 0.27-0.57 μg/ml. 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. 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. It is toxic to rats with an acute LD50 value of 3.8 mmol/kg. Formulations containing cymoxanil have been used to prevent fungal growth on crops and treat late potato blight in agriculture.
Agricultural fungicide.
