摘　　要：本试验以木霉菌(Trichoderma spp.)为生防筛选材料,针对茄腐皮镰刀菌(Fusarium solani),通过对峙培养、难挥发性代谢产物的拮抗试验以及6种杀菌剂对病原菌的毒力测定,为川芎根腐病的生物和化学防治提供参考的理论依据。明确了菌株T131-21对茄腐皮镰刀菌的拮抗效果最好,抑制率达到60.68%。木霉菌株T131-2的难挥发性代谢产物对茄腐皮镰刀菌的抑制作用最好,抑制率达到63.82%。70%甲基托布津在室内试验效果显著,其次是50%多菌灵,EC50(μg/mL)分别是4.1563和48.2079。Trichoderma spp.was used as screening of biocontrol material and Fusarium solanias target strain in this experiment.Reference theoretical basis on biological and chemical control of root rot on Ligusticum wallichiiwas provided by dual culture,antagonistic tests on nonvolatile metabolites and six kinds of fungicides against the pathogen virulence test.It was clear that strain T131-21 had best antagonistic effect to Fusarium solani,the inhibition rate reached 60.68 ％.Non-volatile metabolites of Trichoderma T131-2 had good inhibition result on Fusarium solani,inhibition rate reached 63.82％,70％ thiophanate had significant effect in laboratory tests,followed by 50 ％ carbendazim,EC50 （μg/mL） were 4.1563 and 48.2079,respectively.
