The effect of ammonium molybdate (NH 4 Mo) as an additive to improve biocontrol efficacy of antagonistic yeasts Rhodotorula glutinis and Trichosporon sp. against blue mold and Alternaria rot of pear fruits caused by Penicillium expansum and Alternaria alternata , respectively, was evaluated. Biocontrol activity of R. glutinis was enhanced in combination with NH 4 Mo, whereas the efficacy of Trichosporon sp. was not improved. Combining R. glutinis with 1 mmol l −1 NH 4 Mo provided a more effective control on P. expansum and A. alternata than applying the yeast or NH 4 Mo alone. Addition of 1 mmol l −1 NH 4 Mo significantly affected the growth of R. glutinis and Trichosporon sp. in nutrient yeast dextrose broth medium, but did not affect the growth of R. glutinis and Trichosporon sp. in pear wounds. Thus, it appears that the use of NH 4 Mo is a useful approach to improve the efficacy of R. glutinis for postharvest disease control. Copyright © 2005 Society of Chemical Industry
