摘要
菊花白锈病是菊花重要的流行性病害,也是世界检疫性病害。针对菊花白锈病选取10种保护性药剂和13种治疗性药剂进行田间试验,筛选出了效果好、成本低的粉锈宁1000倍液和甲壳素+冰醋酸1000倍液作为保护性药剂交替使用,腈菌唑8000倍+代森锰锌1200倍液和黑杀3000倍液作为治疗性药剂交替使用。还针对带菌插穗进行药剂处理,提出先蘸世高4000倍液再蘸生根粉,为从种苗切断传染源提供了依据。这些结果为有效控制菊花白锈病的传播提供了保证。
The chrysanthemum white rust （ CWR ） , caused by Puccinia horiana Henn. , is one of the most important epidemic diseases on Chrysanthemum, and also is a quarantine action pest in the world. The effectiveness of 10 chemical compounds as preventively applications and 13 chemical compounds as curatively applications in the control of CWR were tested. The result showed that triadimefon 1000-fold and Chitin plus acetic acid 1000-fold in preventively applications and Myclobutanil 8000- fold plus Mancozeb 1200-fold and Diniconazole 3000-fold in curatively applications were more effective and with relatively low-cost, which made them alternative in control of CWR. Besides, infected cuttings were treated with chemical compounds, which aimed at cutting off the source of infection from infected cuttings. All these results guaranteed effective control of CWR spreading, and provided a basis for application in production.
