The yeast Debaryomyces hansenii reduced the incidence of Penicillium digitatum and P. italicum decay of oranges. A water suspension of the yeast cells applied to wounds on the surface of the fruit prior to inoculation with spore suspensions of pathogens reduced disease by 80-90%. The efficacy of the antagonist in the reduction of green and blue mould was affected by the concn of both the yeast cells and spore suspension. No reduction of disease was exhibited by an autoclaved preparation of yeast cells or by a yeast culture filtrate. D. hansenii did not inhibit the growth of the pathogens on PDA. The antagonist grew readily on injured citrus fruit leachate and multiplied rapidly on wound sites.
