Documented Uses

• Used as agricultural fungicide; [Merck Index] Used to control blight on tomatoes and potatoes and downy mildew on cucurbit vegetables; [Reference #1]
• For control of diseases caused by oomycete fungi. ... controls early and late blight on tomatoes and potatoes and downy mildew on cucurbit vegetables (crop group 9).
• For control of Oomycete and Plasmodiophora diseases, such as potato and tomato late blight (Phytophthora infestans) and downy mildews (e.g. Pseudoperonospora cubensis of cucumber).
• Preparation: R. Nasu et al., AU 8812883; eidem, US 4995898 (1988, 1991 both to Ishihara Sangyo Kaisha)
• Cyazofamid has limited systemic activity so it is used as a protectant fungicide applied by ground or aerial spray.
• Both the urine and feces were major routes of excretion /in rats/ at the low dose /0.5 mg/kg/ with most of the urinary radioactivity being a metabolite named CCBA (4-(4-chloro-2-cyanoimidazol-5-yl)benzoic acid). ... Irrespective of the dosing regimen, most of the recovered fecal radioactivity was unchanged parent compound; the major fecal metabolites were CCBA and 4-chloro-5-p-tolylimidazole-2-carbonitrile (CCIM) each of which being less than 5% of the administered dose.
