AB Dibromodimethylhydantoin impregnated in paper wrappers and sodium metabisulfite and dibromotetrachloroethane impregnated in both paper or sawdust were tested for their effect on Botrytis decay of stored Emperor grapes. Standard sulfur dioxide fumigation was also evaluated in one of the experiments with impregnated tissue wraps. Dibromotetrachloroethane proved to be the most effective material in reducing fungus sporulation and in eliminating contact decay in wrapped grapes. Its fungistatic action was found to be additive to that of sulfur dioxide. Best control of Botrytis was obtained by impregnating sawdust with dibromotetrachloroethane. No adverse effects of this material on appearance or palatability of grapes were observed in any of these experiments. Low residues of dibromotetrach-loroethane were found on grapes after a 4l-day storage. Some dissipation of this chemical appeared to occur after exposing treated fruit to the air.
