摘要
[目的]生产上缺乏防治人参根腐病的有效药剂,为有效防治人参根腐病提供理论依据。[方法]采用生长速率法测定了24种杀菌剂及7种药剂的34种配比对人参根腐病菌的毒力,并进行田间防效试验。[结果]8%井冈·32%蜡芽菌WP、50%多菌灵WP抑菌效果较好,其EC90值分别为0.56、6.65 mg/L。具有增效作用的药剂配比有5个,2亿/g木霉菌WG+97.8%多菌灵TC 2∶3配比增效作用最为明显,其共毒系数为822.26。50%多菌灵WP和2亿/g木霉菌WG+97.8%多菌灵TC 2∶3配比在田间表现出较好的防效,防效均在65%以上。[结论]筛选出防治人参根腐病菌的有效药剂及配比,为更有针对性地防治人参根腐病奠定基础。
Based on lack of effective fungicides to control ginseng root rot caused by Fusarium solani in ginseng production, the aim of this research is to provide a theoretical basis for controlling ginseng root rot. [Methods] Toxicities of 24 fungicides and 34 proportions of 7 fungicides against E solani were tested by mycelium growth rate method in laboratory, and field trials against E solani were also conducted. [Results] Validamycinbacillus cereus 8%＇32% WP, carbendazim 50% WP had better toxicity, the ECgo values were 0.56 and 6.65 mg/L, respectively. Five proportions had synergistic action, the most obvious synergistic action was trichoderma 2 billion/g WG＋carbendazim 97.8% TC 2 ： 3, the CTC were 822.26. Carbendazim 50% WP and lrichoderma 2 billion/g WG＋carbendazim 97.8% TC 2 ： 3 had better field control effects with more than 65%. [Conclusions] Effective fungicides and proportions were screened out, which laid a foundation for better controlling ginseng root rot.
