| 中文摘要: |
| 毛葡萄穗轴溃疡病主要危害果穗穗轴, 引起果穗枯死和果实大量脱落, 造成果实产量降低。本研究对该病的病原菌进行分离、致病性测定, 并通过形态学特征、ITS rDNA和EF-1α基因序列分析将该病的主要病原鉴定为小新壳梭孢菌(Neofusicoccum parvum)。通过抑制菌丝生长法在室内初步筛选防治该病的药剂, 试验结果表明, 在测试的26种药剂中, 30%氟硅唑微乳剂、64%噁霜·锰锌可湿性粉剂、70%戊唑·丙森锌可湿性粉剂、70%代森锰锌可湿性粉剂、22.2%抑霉唑乳油、70%丙森锌可湿性粉剂及60%唑醚·代森联水分散粒剂等7种药剂对该病病原的抑制作用较强, 抑菌率均达100%, 可作为备选药剂进行田间防治试验。 |
| 英文摘要: |
| Panicle canker pathogen damaged the panicle of Vitis heyneana, caused a large number of fruits drop and reduced the yield seriously. The pathogen was isolated and its pathogenicity was tested. Based on morphological characteristics, ITS rDNA and EF-1α gene sequences analysis, the pathogen was identified as Neofusicoccum parvum. Inhibitory activity analysis of 26 kinds of fungicides demonstrated that 7 kinds of fungicides including flusilazole 30% ME, oxadixyl·mancozeb 64% WP, tebuconazole·propineb 70% WP, mancozeb 70% WP, imazalil 22.2% EC, propineb 70% WP and pyraclostrobin·metiram 60% WG showed high inhibitory rates of 100% on N. parvum. Thus, these 7 kinds of fungicides can be recommended as alternative agents for field testing. |
