Evaluation of the synergy between Schwanniomyces vanrijiae and propolis in the control of Penicillium digitatum on lemons

Abstract Background Green mold disease on citrus caused by Penicillium digitatum is the most serious and destructive disease. It causing 90% of production losses during post-harvest handling. Results In this study, activity seven yeast isolates from lemons against P. , a fungal pathogen that causes green in lemons, was isolated examined. vitro experiments showed isolate three significantly reduced growths were later identified as Schwanniomyces vanrijiae . addition, 3% ethanolic extracts propolis (EEP) strong mycelial growth inhibition with halos 1.4 cm. The use S. treatments to protect lemon fruits has been reported (55%); however, reports describing application EEP are limited (40%). Thus, effectiveness combination an antagonistic mixture for protecting applied alone both vivo conditions. combined + severity incidence (80 93.7%, respectively) much higher efficacy than either treatment alone. Lemon treated increased levels antioxidants, peroxidase (POD), polyphenol oxidase (PPO), phenol untreated control. Conclusion results indicated can strongly compared sole bioagent.
