Post-harvest losses due to plant pathogens is a major problem in grapes which causes huge economic losses to the farmers in terms of quality and quantity. Yeast are unicellular organisms which exist on the fructosphere of crops and protects the plant from pathogens. In this study, yeast species has been exploited against Rhizopus
sp. infecting grapes during the post-harvest stage. Thirty-three epiphytic
yeasts on the surface of grapes were isolated from Madurai and Erode districts of Tamil Nadu and tested against Rhizopus
sp. The results revealed that the yeast isolate, YCSL2 exhibited maximum inhibitory effect of 30.33% and 24.44% in dual culture and volatile compounds assay respectively over the control
under in vitro
. Similarly, wound site colonization of yeast against Rhizopus
sp. recorded maximum inhibitory effect of 71.11% against the control under in vivo
. Thus, the yeast species identified in this study can be used for the biological management of post-harvest pathogens in grapes.
