由Phomopsis mangiferae 引起之檬果採收後病害發生調查及防治藥劑篩選

Abstract

＂Phomopsis mangiferae＂係引起台灣檬果果實果腐病及蒂腐病病原菌之一，本研究針對該病原菌進行其在田間引起病害之發生率調查及其防治藥劑篩選評估。由2009–2011年間在台南市玉井及官田地區之愛文檬果果實採後病害調查資料顯示，官田地區檬果果實發生採後果腐或蒂腐病之平均罹病率有51.5%，皆由＂P. mangiferae＂所引起，明顯高於玉井地區之11.9%。由此得知，官田地區的果腐病或蒂腐病之主要病原菌為＂P. mangiferae＂。 Phomopsis mangiferae is one of pathogens causing stem-end rot or fruit rot disease of mango in Taiwan. The objectives of this study were to survey and screen fungicides for mango postharvest diseases caused by P. mangiferae. A field survey was performed at Yujing and Guntian Townships in Tainan City during 2009-2011.
