摘　　要：为评价不同类型病毒抑制剂在不同发病条件下对烟草花叶病的防控效果,选用2种生物制剂(AHO、宁南霉素)和2种化学农药(吗胍.乙酸铜、烯.羟.硫酸铜)进行田间药效试验。大田接种烟草花叶病毒(TMV)的试验表明,AHO和吗胍.乙酸铜对TMV的平均防效较高,分别为41.8%和39.8%,宁南霉素和烯.羟.硫酸铜对TMV的平均防效较低,分别为25.4%和14.5%;在自然发病状态下,AHO对TMV的平均防效为45.5%,宁南霉素的平均防效次之,为36.6%,而烯.羟.硫酸铜和吗胍.乙酸铜的平均防效则分别为28.7%和16.2%。AHO在不同带毒环境下防控烟草花叶病的效果都优于其他3种市售药物,表明其具有开发成为绿色抗烟草花叶病新型农药的潜力。To evaluate the effect of two different types of virus inhibitor on tobacco mosaic virus（TMV） under different conditions,two biological agents（AHO,Ningnanmycin） and two chemical pesticides（Moroxydine blue verdigris,Olefinic hydroxyl copper sulfate）were used to test their control effect on TMV in the field.The results showed that under the challenging inoculation condition,AHO and Moroxydine blue verdigris had better control effects on TMV with the average relative control effects of 41.8% and 39.8%,respectively.The average relative control effects of Ningnanmycin and Olefinic hydroxyl copper sulfate were 25.4% and 14.5%,respectively.In the natural disease state,AHO had an average control efficiency of 45.5% on TMV,followed by Ningnanmycin,whose average control effect was 36.6%.While Olefinic hydroxyl copper sulfate and Moroxydine blue verdigris had a lower average control effect of 28.7% and 16.2%,respectively.AHO had a better effect of prevention and control on TMV than the other three kinds of commercial pesticides under different disease conditions,suggesting that it has a potential to be developed into new green anti-TMV pesticide.
