摘　　要：为了探究龙胆草根腐病的化学防治措施,筛选出龙胆草根腐病的有效防治药剂,本试验在绿色植物生长调节剂GGR的基础上,进一步搭配使用精甲·恶霉灵、宁南霉素、哈茨木霉菌、枯草·地衣芽孢杆菌以及乙蒜素共5款杀菌剂,通过大田试验验证不同药剂组合对龙胆草根腐病的防治效果。结果表明:GGR单独使用及与供试的5种药剂搭配使用对龙胆草的根腐病均具有一定的防治效果,其中,GGR+2×10^(10) CFU·g^(-1)枯草·地衣芽孢杆菌和GGR+3×10^(8) CFU·g^(-1)哈茨木霉菌两个药剂组合的综合效果最好,病害防效分别可达到49.55%和45.23%,单独使用GGR防效也可达到18.85%。GGR与5款杀菌剂均可作为防治龙胆草根腐病的参考用药,GGR+2×10^(10) CFU·g^(-1)枯草·地衣芽孢杆菌和GGR+3×10^(8) CFU·g^(-1)哈茨木霉菌可作为防治龙胆草根腐病的首选药剂搭配组合。In order to explore the chemical control measures of gentian root rot and screen out the effective control agents for the prevention of gentian root rot,based on the green plant growth regulator GGR,this experiment further used five fungicides,including Jingjia·oxamyl,ningnanmycin,Trichoderma harzianum,Bacillus subtilis·licheniformis and allicin.Field experiments were conducted to verify the control effects of different chemical combinations on gentiana root rot.The field experiment showed that GGR alone and in combination with the five tested chemicals had certain control effects on the root rot of gentian grass.Among them,the combination of GGR+2×10^(10) CFU·g^(-1) Bacillus subtilis and GGR+3×10^(8) CFU·g^(-1) Trichoderma harzianum had the best comprehensive control effects,which could reach 49.55%and 45.23%respectively,the control effect of GGR alone can also reach 18.85%.GGR and five fungicides can be used as reference drugs for the prevention and control of gentian root rot.GGR+2×10^(10) CFU·g^(-1) Bacillus subtilis·licheniformis and GGR+3×10^(8) CFU·g^(-1) Trichoderma harzianum can be used as the first choice for the prevention and control of gentian root rot.
