摘要
Shaabo, A.， N. Deeb, M. Mufleh, R. Zaydan, A. Haj Hasan, L. Adra, A. Askriyeh和N. Sakkour. 2022。化学和生物防治成分对马铃薯早疫病的防治效果及其对生长和产量的影响植物保护学报，40(4):325-333。https://doi.org/10.22268/AJPP-40.4.325333本研究于2021年春季在叙利亚拉塔基亚农业科学研究中心的Alsonawbar站进行，以评估不同处理对马铃薯早疫病的控制效果，以及它们对植物生长和马铃薯产量和品质的影响。在对照的基础上，选用化学农药Ranman 20% SC(氰唑菊)、Moximate 50% WP (cymoxanil + mancozeb)和3种生物农药枯草芽孢杆菌、球孢白僵菌和黑僵木霉。结果显示，Ranman治疗效果较好，治疗2周后病情严重程度和感染率分别降低20.18%和5.61%，较对照组分别降低25.80%和20.46%。在相同处理下，叶面积和叶面积指数分别达到8438.75 cm2 /株和3.45 cm2 /m2，比对照处理分别增加4827.75 cm2 /株和1.97 m2 /m2。结果表明，枯草芽孢杆菌处理在块茎数量、块茎重量、产量和商品率方面均具有优势，分别达到8.16根/株、93.47 g/根、3126.94 kg/株、95.30%的商品率，分别比对照降低20.09%、30.99%、42.31%、9.72%。此外，化学农药处理的干物质和淀粉含量最高。关键词:茄疫病，马铃薯，化学防治，生物防治，生产
