DOCUMENT TYPE: Patent CA Section: 5 (Agrochemicals) Section cross-reference(s): 28 The hydantoin derivs. I (X and Y = halogen) are prepd. and are used as fungicides. For example, 1-cyanomethyl-3-(3,5-dichlorophenyl)-4-iminoimidazolidin-2-one (II) [21885-74-5] was prepd. by treating iminodiacetonitrile [628-87-5] with 3,5-dichlorophenyl isocyanate [34893-92-0]. II applied at 125 ppm to beans prevented Sclerotinia sclerotiorum infection. .
