| 摘 要： | 近年来垂柳锈病在内蒙古地区危害日趋严重。病原菌的性孢子、锈孢子(0、Ⅰ)阶段发生在紫堇(Corydalis bungeana Turz.)叶、茎、果上;夏孢子、冬孢子(Ⅱ、Ⅲ)阶段发生在垂柳(Salix babylonica L.)上。取垂柳病叶上越冬后的冬孢子堆,待其萌发后接种,只有紫堇感病,产生与自然状态下相同的典型症状,首次发现紫堇是垂柳锈病病菌的转主寄主。采用25％粉锈宁800倍液、及其与25％多菌灵混合液对垂柳锈病的防治效果较好。用2.4—DJ酯800、1000倍液防治转主寄主紫堇效果较为理想。

| Abstract: | The rust of weeping willow has been serious gradually since current years in the Inneer Mongolia. Its spermagonium and aecial state occur on leaves, stems and fruits of Corydal is edulis and theuredial and telial states grow on the leaves of weeping willow. Inoculation with basidiospores produced from the teliospores overwintered were made on 8 different plants, but noly C. bungeana showed the typical systems on leaves after inoculation. The best chemical for controlling the disease dimefon, triadirriefon with carbendazim mixture, 2.4-D. |
