Abstract: Biocontrol efficacy of antagonistic yeast Crytococcus laurentii in combination with different concentrations of sodium bicarbonate (SBC) against postharvest diseases caused by Botrytis cinerea and Pythium aphanidermatum in tomato fruit were investigated. The results indicated that combining C. laurentii with SBC provided a more effective control on B. cinerea and P. aphanidermatum than applying the antagonistic yeast or SBC alone, and C. laurentii combined with 5% SBC showed the best effect. Growth of B. cinerea and P. aphanidermatum were inhibited on PDA containing different concentrations of SBC and the inhibitory effect on B. cinerea was stronger than on P. aphanidermatum. Growth of C. laurentii was inhibited by SBC both in the wound of tomato fruit and NYDB broth.
