中文摘要 | 本計畫旨在調查北部地區長壽花病害種類、病徵及發生時期,並篩選防治藥劑, 供栽培業者參考。北部地區長壽花病害調查結果發現灰黴病菌(Botrytis cinerea)可 感染葉、花梗及花;炭疽病(Anthracnose)造成葉片壞疽斑點;白粉病(Powdery mildew) 感染葉片及莖;腐霉菌(Pythium spp.)主要發生於苗期,感染根系造成根腐病(Root rot);此外,還有造成莖及葉片表面瘡痂症狀、葉面凸起木栓化等之葉斑病 (Stemphylium leaf spot)病徵。藥劑篩選結果23%亞托敏水懸劑稀釋2,000 倍、24.9% 待克利乳劑稀釋3,000 倍、42.2%腈硫醌水懸劑稀釋1,200 倍可完全抑制長壽花炭疽病 菌生長;而80%鋅錳乃浦可濕性粉劑稀釋500 倍及75%四氯異苯腈水分散性粒劑稀釋 600 倍可抑制葉斑病菌生長。 |
英文摘要 | The study was conducted to investigate the major kalanchoe diseases in Northern Taiwan, and try to test the effects of several fungicides on the related pathogens. We found five kalanchoe diseases caused by fungi. These are gray mold disease of flowers, stalks and leaf, caused by Botrytis cinerea, anthracnose caused by Colletotrichum gloeosporioides, powdery mildew on leaf and stem caused by Sphaerotheca fuliginea, root rot caused by Pythium spp. and the leaf spot caused by Stemphylium spp. The fungicide test showed that 23% Azoxystrobin SC 2000×, 24.9% Difenoconazole EC 3000× and 42.2% Dithianon SC 1200× can inhibit the mycelial growth of Colletotrichum gloeosporioides. Where as 80% Mancozeb WP 500× and 75% Chlorothalonil WG 600× can inhibit the mycelial growth of Stemphylium spp. |
