Physical treatments combined with C. membranifaciens could be an alternative to fungicides use in postharvest treatment for the control of the green mold on orange

In order to control the green mold on orange, the effect of physical postharvest treatments, using hot water brushing (HWB) and ultraviolet C irradiation (UVC), alone or in combination with antagonistic yeast (Candida membranifaciens CMAA-1112 (*)) was studied. The mechanisms involved in the biocontrol and the effects of these treatments on postharvest quality of fruit were also investigated. The results showed that HWB at 55 ?C for 30 s and UVC at 2 kJ m?2 stand-alone were capable of reducing the decay progress in around 70%. Candida membranifaciens CMAA-1112 was effective in reducing the disease severity, and the main mechanism of control was by inducing systemic resistance on fruit peel. The combination of physical treatments and C. membranifaciens presented an additive effect increasing the efficacy in controlling the disease, and extended the fruit shef-life. Our data suggest that the integration of physical treatments combined with C. membranifaciens could be an alternative to fungicides use in postharvest treatment for the control of the green mold on orange.
