    八达岭林场黄栌枯萎病防效研究

    Control effect of Verticillium wilt on Cotinus coggygria inBadaling Forest Farm of Beijing

      摘要
    • 摘要:
      目的 研究不同药剂组合和施药技术对八达岭林场黄栌枯萎病林间控制效果，探讨黄栌枯萎病有效防控措施，旨在保障北京地区黄栌健康和红叶景观安全。
      方法 选择枯草芽孢杆菌、50%嘧菌酯、156 g/L丙环唑、50%多菌灵和45%咪鲜胺等5种药剂，采用灌根、树干注射和两者相结合的施药方式，共设置12个处理，对八达岭林场黄栌枯萎病开展林间防治试验。
      结果 通过比较各处理在2021—2022年间黄栌枯萎病病情指数，得出当年防治效果最好的施药组合是灌根丙环唑结合树干注射多菌灵与嘧菌酯复配，校正病情指数为5，防治效果达到88%。并且，该组合中有26.67%植株保持健康，健康植株数量最多。第2年5月病情指数最低的施药组合是灌根枯草芽孢杆菌结合树干注射多菌灵与嘧菌酯复配，表现出较好的治疗效果，健康植株数量最多，且往年重度发病样树均转为无病或轻度发病，病情指数仅有3.33。其他施药方式和药剂组合均在不同程度上缓解黄栌枯萎病的发生，但是不同处理的防治效果统计学上存在显著差异（P < 0.05）。
      结论 本研究结果表明灌根丙环唑和树干注射多菌灵与嘧菌酯复配组合防治效果最佳，灌根枯草芽孢杆菌结合树干注射多菌灵与嘧菌酯复配组合在感病治疗及防治效果方面均表现良好，两者均可作为黄栌枯萎病的防治方案。

       

      Abstract:
      Objective This paper studies the control effect of Verticillium wilt of smoke tree (Cotinus coggygria) in Badaling Forest Farm of Beijing by studying the effect of different combinations of chemicals and application techniques, explores effective methods for the prevention and control of Verticillium wilt to ensure the health of C. coggygria and the safety of red leaf landscape in Beijing.
      Method We selected five fungicides including Bacillus subtilis, 50% azoxystrobin, 156 g/L propiconazole, 50% carbendazim and 45% prochloraz and set up 12 treatments to control Verticillium wilt in Badaling Forest Farm by injecting root and trunk or a combination of both.
      Result Analysis of the 2021 control data showed that the combination treatment 12 (root irrigation of propiconazole combined with trunk injection of carbendazim and azoxystrobin) was most effective, with a corrective disease index of only 5, significantly different from control (P < 0.05) and a corrective control effect of 88%. By comparing the disease indices of each treatment for the period of 2021−2022, it was found that the most effective control combination for that year was root injection of propiconazole combined with trunk injection of carbendazim and azoxystrobin, with a corrected disease index of 5 and control effectiveness was 88%. Moreover, 26.67% of trees in this combination treatment remained healthy and had the highest number of healthy trees. The combination with the lowest disease index in May of the following year was a combination of Bacillus subtilis with root irrigation combined with trunk injections of carbendazim and azoxystrobin, which showed a good treatment efficacy with the highest number of healthy trees, and the severely diseased sample trees from previous years all turned to be healthy or lightly diseased. And the combination had a disease index of only 3.33.
      Conclusion This study suggests that the combination of propiconazole in root irrigation and trunk injections of carbendazim and azoxystrobin is most effective, and that the combination of Bacillus subtilis in root irrigation and trunk injection of carbendazim and azoxystrobin performs well in terms of disease treatment and control, both of which can be used as control options for Verticillium wilt.
