It is a systemic protectant and curative which acts by inhibiting sterol biosynthesis in fungi. Fenbuconazole is rapidly absorbed and eliminated, mainly in the faeces through significant biliary excretion; there was no evidence of significant retention in tissues. Fenbuconazole was of low acute toxicity when administered orally (LD50 > 2000 mg/kg bw), dermally (LD50 > 5000 mg/kg bw), or by inhalation (LC50 > 2.1 mg/litre air). It was not irritating to the skin or eyes."}]
