| 摘 要： | 通过在灰霉病菌（Botrytis cinerea）分生孢子悬浮液中加入1%酵母浸膏、2.5%葡萄糖和10%胡萝卜汁，接种离体黄瓜子叶，病叶率及发病均匀度较高，确立了一种重复性好、操作简便的测定杀菌剂对灰霉病菌毒力的新方法-黄瓜子叶喷雾法。以该方法、菌丝生长速率法和孢子萌发法分别测定比较了戊唑醇、代森锰锌和异菌脲对灰霉病菌的毒力，发现药剂浓度的对数值与其抑制率的几率值之间有很高的相关性，相关系数均大于0.95。该方法可用于灰霉病菌抗药性监测和杀菌剂敏感性测定。 |

| Abstract: | To seek for a high sensitive and high accuracy method to screen fungicides, in this research, a new test (cucumber cotyledons spray inoculation test) of Botrytis cinerea was established through inoculation on cucumber cotyledons with conidial suspension of B. cinerea amended with 1% yeast extract, 2.5% glucose and 10% carrot juice. The results showed that the test exhibits high disease incidence (100%) and uniform disease severity (>98% ), good repetition and simple operation. Inhibitory activity of tebucon... |
