【摘要】 绿竹叶锈病为绿竹Dendrocalamopsisoldhami上的一种新病害。该病的严重发生给绿竹生产造成了很大的危害。对绿竹叶锈病的发病规律和病原等方面进行了较详细的研究,确定病原为担子菌亚门冬孢菌纲锈菌目半知锈菌类夏孢锈菌属竹夏孢锈菌Uredoignava。在此基础上对绿竹叶锈病进行了防治药剂筛选和田间防治试验。试验结果表明,粉锈宁和克菌宁2种药剂对该锈菌夏孢子的萌发抑制效果较好,抑制率分别达到70 01%和66 45%。图2表2参5更多还原

【Abstract】 The leaf rust of Dendrocalamopsis oldhami is a new bamboo disease which has badly harmed the growth and quality of D. oldhami. The careful study of etiology and pathogeny of this disease showed that the pathogeny of it was Uredo ignava which belonged to Basidiomycotina Teliomycetes Uredinales. On the basis of the study, the selection of control chemicals and field control tests was conducted. The tests showed that the fungicides of Triadimefon and Kejunning could satisfactorily control the germination of the urediniospore of Uredo ignava, their effective rates being 70.01% and 66.45% respectively.更多还原
