| 中文摘要: |
| 水稻窄条斑病是浙江杭州地区的新病害, 本研究从症状识别、种子传病及防治药剂测试三方面入手对该病害进行研究。结果表明, 通过对光观察病斑透明度, 观察有无菌脓及喷菌现象可有效地将水稻窄条斑病与水稻细菌性条斑病区分开; 水稻窄条斑病种子可带菌传病, 传病率因品种和种子来源不同而异; 25％丙环唑EC和50%多菌灵WP对水稻窄条斑病均有较好防效, 其中以25％丙环唑EC有效成分用量150 g/ hm2为最佳, 防效达68.73%。 |
| 英文摘要: |
| Narrow brown leaf spot of rice is a new fungal disease in some rice growing areas of China. In order to effectively control the disease, the symptom diagnosis, seed transmission and fungicide control were investigated. The results showed that the disease could differentiate from bacterial leaf streak of rice by observing the symptoms of semi transparent lesions, bacterial ooze and bacterial steaming. Narrow brown leaf spot of rice caused by Cercospora oryzae is seed-borne and seed transmitted disease. The transmission rate varied with different cultivars and origins of rice seeds. 25% propiconazole EC and 50% carbendazim WP had better effect against the disease and spraying 25% propiconazole EC at 150 g/hm2 showed the highest efficacy of 68.73%. |
