| Summary: | © 2015 Society of Chemical Industry. BACKGROUND: This study investigated both the in vitro and in vivo biofumigant ability of the endophytic fungus Muscodor suthepensis CMU-Cib462 to control Penicillium digitatum, the main cause of tangerine fruit rot. RESULTS: Volatile compounds from M. suthepensis inhibited mycelial growth of the pathogen. The most abundant compound was 2-methylpropanoic acid, followed by 3-methylbutan-1-ol. They showed median effective doses (ED 50 ) on P. digitatum growth of 74.91 ± 0.73 and 250.29 ± 0.29 μL L -1 airspace respectively. Rye grain was found to be a suitable solid medium for M. suthepensis inoculum production. The results indicated that mycofumigation with a 30 g rye grain culture of M. suthepensis for 12 h controlled tangerine fruit rot. The percentage weight loss and soluble solids concentration of fumigated tangerines were similar to those of non-infected and non-fumigated fruits. CONCLUSION: Muscodor suthepensis has potential as a biofumigant for controlling postharvest disease of tangerine fruit. |
