| 中文摘要: |
| 通过鉴定发现引起甘肃省康乃馨锈病的病原为石竹单胞柄锈菌（Uromyces dianthi Niessl.）；分别采用孢子萌发法和田间喷雾法、灌根法对防治康乃馨锈病的药剂进行了室内筛选和田间药效试验。结果表明，12.5%烯唑醇可湿性粉剂、25%嘧菌酯悬浮剂等7种药剂对康乃馨锈病夏孢子的萌发抑制率均超过50%；对筛选出的7种药剂进一步进行田间药效试验，发现采用喷雾法时12.5%烯唑醇可湿性粉剂、25%嘧菌酯悬浮剂和10%苯醚甲环唑水分散粒剂三种药剂的防效高于其他几种药剂，分别达70.2%、68.3%和65.0%，而灌根法对康乃馨锈病的防效并不理想，最高防效仅为8.1%。 |
| 英文摘要: |
| The pathogen of carnation rust in Gansu Province was identified to be puccinia single cell (Uromyces dianthi Niessl.); Laboratory experiments and field tests were conducted to screen effective fungicides against carnation rust by spore germination, field spraying, and irrigation root methods. Laboratory experiments showed that 12.5% diniconazole WP, 25% azoxystrobin SC and other 5 kinds of fungicides could inhibit the urediospores germination by over 50%. Field tests indicated that control efficacy of 12.5% diniconazole WP, 25% azoxystrobin SC and 10% difenoconazole WG was higher than that of other fungicides by spraying method, with efficiency of 70.2%, 68.3 % and 65.0%, respectively. However, control effect by irrigation root methods was poor, with a maximal efficiency of 8.1%. |
