Fluid fungicidal compsns. contain, by wt., (a) 20-40% iprodione (I; 1-isopropylcarbamoyl- 3-(3,5-dichlorophenyl)hydantoin) as active component; (b) an oil-in-water emulsion contg. 50-160%, on (I), of an oil with HLB 8-12, pref. 10-11; (c) 0.1-2% ethoxy-lated fatty alcohol or nonionic emulsifier and (d) opt. 0.5-2.5% neutral, hydrophilic silica. Pref. the oil can dissolved 1-5g (I) per l at room temp. and may be a mineral or vegetable oil; esp. it has viscosity 20-30 cSt. The most pref. emulsifier is derived from 13C alcohols condensed with 9-10 moles ethylene oxide and the silica is esp. hydrated pptd. silica of BET surface 200-300 sq. m. per g. - (I) is esp. useful for controlling Botrytis Cinerea, particularly on vines. These formations are more effective than conventional wettable powders and are easier to handle (no formation of dust) and are less easily washed off by rain.
