| 摘 要： | 石斛锈病为齿瓣石斛（Dendrobium devonianum Paxt．）上的一种新病害。通过对锈病病斑的形状、颜色和冬孢子的外观形态进行观察，确定病原为担子菌门冬孢菌纲锈菌目柄锈菌属真菌。对锈病进行田间药剂防治试验，结果表明，43％戊唑醇SC、10％苯醚甲环唑WG、15％三唑酮WP三种药剂对该病防治效果较好，相对防效分别达到81．14％、76．36％和76．33％。

| Abstract: | Dendrobium Rust is a new kind of disease found on Dendrobium devonianum Paxt. Through observation of the rust spots of shape, color and the shape of teliospore, this paper determined that diseaseresistance was basidiomycotina teliomycetes Uredinales Puccinia fungus Persoon. Four fungicides were used to test the control efficacy to Dendrobium rust in the field. The results showed that Tebuconazole 43% SC, followed by 10% Difenoconazole WG ,15% Triadimefon WP, performed the best in controlling Dendrobium Rust. The control effect reached 81.14%, 76.36% and 76.33% respectively. |
