Documented Uses

• Used as synthetic strobilurin agricultural fungicide; [Merck Index] Used to control powdery mildew in greenhouse ornamental crops; [Reference #2]
• The product is applied as a spray (backpack sprayers or overhead booms) to control powdery mildew on the following greenhouse-grown ornamental crops: ageratum, dahlias, dianthus, dusty miller, gazania, geraniums, marigolds, pansies, portulaca, snapdragons, spirea, spengril, verbena, vinca, zinnia, poinsettias, roses, cut flowers, oak trees, and dogwood trees.
• Prepn: TA Andrea, PHT Liang, EP 502,740; eidem, US 5,393,734 (1992, 1995, both to DuPont)
• Chemicals that kill or inhibit the growth of fungi in agricultural applications, on wood, plastics, or other materials, in swimming pools, etc.
• In a metabolism study, kresoxim-methyl was admin to rats as single gavage doses or 50 or 500 mg/kg or 15-day repeated doses of 50 mg/kg, or as a single iv dose of 5 mg/kg/day. Radiolabeled test compound was included in one 500 mg/kg dose group to facilitate metabolite identification. Biliary metabolites were assessed in rats with cannulated bile ducts given an oral dose of 50 or 500 mg/kg/day. Orally admin test compound was widely distributed & quickly eliminated. Results indicated there was no bioaccumulation. In
• A total of 32 different metabolites were identified in the urine, feces, bile, plasma, liver, & kidneys of rats. There were some sex, dose, route, & label-dependent differences in the metabolite profiles.
