荔枝針點病之病原菌為Colletotrichum siamense，可危害荔枝葉片與葉柄，造成黑色針點狀病斑。本研究由雲林古坑「糯米糍」及「桂味」荔枝品種之針點病病斑上分離得Colletotrichum spp.，經形態觀察及分子類緣關係鑑定確認為C. siamense。
The causal agent of lychee pepper spot disease is Colletotrichum siamense. The symptom shows black needle-like spots on leaf, fruit, petiole and pedicle. In this study, many isolates of Colletotrichum spp. were isolated from needle-like spots on lychee 'Gue Wei' and 'No Mi Ci' and all of them were identified as C. siamense based on morphology and molecular phylogenetic analysis. In our previous study, the pathogenicity of C. siamense on lychee has been validated on lychee 'No Mi Ci'. In this study, pathogenicity test was conducted on lychee 'TN 7' to confirm that the pathogen causes symptoms on other variety in addition to 'No Mi Ci'.
