Abstract
榴槤為東南亞地區之重要熱帶果樹，其對環境條件敏感，在栽培生長的過程也會遭遇許多病蟲害，國外報導最常見的病害包括葉斑病、炭疽病、白粉病、疫病與枯枝病。本研究首次調查臺灣榴槤葉斑病發生情形並進行病原性測試，調查結果顯示，所調查的葉斑病葉片以Phomopsis 屬的真菌分離率最高，所有調查的榴槤品種均會發生此病害。於2025 年4−11 月份的調查顯示，5 月是病害發生相對高峰期，且上層葉與下層葉葉斑病的罹病率沒有顯著差異，顯示該病害沒有因為植株葉片接受陽光的多寡而有不同，接種結果也顯示有84.2% 的Phomopsis 屬真菌分離株對貓山王榴槤葉片具有病原性，故後續病害防治須將此病原菌納入考量，未來將針對此一類群真菌進行非農藥資材及生物防治試驗，以建立對環境友善的葉斑病病害綜合管理策略。
Durian (Durio zibethinus L.) is an important tropical fruit tree in Southeast Asia and is known for its sensitivity to environmental conditions. During its cultivation and growth, durian is susceptible to a variety of pests and diseases. According to reports from abroad, the most common diseases include leaf spot, anthracnose, powdery mildew, Phytophthora blight, and dieback. This study represents the first investigation of durian leaf spot disease occurrence in Taiwan, along with pathogenicity tests of the associated pathogens. Survey results indicated that Phomopsis species had the highest isolation frequency from symptomatic leaves. All durian cultivars surveyed were found to be affected by this disease. Surveys conducted from April to November 2025 indicated that disease incidence reached a relative peak in May. Furthermore, no significant difference in disease incidence was observed between upper and lower canopy leaves, suggesting that the severity of leaf spot is not influenced by sunlight exposure. Pathogenicity tests showed that 84.2% of the Phomopsis isolates were pathogenic to Musang King durian leaves. Therefore, this fungal group should be taken into serious consideration in future disease management strategies. Moving forward, non－chemical control methods and biological control trials targeting Phomopsis spp. will be conducted, with the aim of developing an environmentally friendly integrated disease management strategy for durian leaf spot disease.
