| 摘 要： | 【目的】评价植物源天然产物3-丙酮基-3-羟基羟吲哚（3-acetonyl-3-hydroxyoxindole,AHO）对田间番茄斑萎病毒属病毒病的防控效果,为AHO开发成为新的抗病毒剂提供科学依据。【方法】选取5%AHO水剂和生产中常用的7种抗病毒剂（超敏蛋白、氨基寡糖素、盐酸吗啉胍、吗呱乙酸铜、宁南霉素、啸克、苯并噻二唑）在烟株移栽还苗后进行叶面喷施3次,药后调查烟株病毒病发生情况。【结果】供试药剂中除啸克外对大田烟株番茄斑萎病毒属病毒病均有很好的防控效果,连续施用3次后可较好地控制烟田番茄斑萎病毒属病毒病的发生和发展,其中,AHO对番茄斑萎病毒属病毒病的相对防效为79.86%,略低于宁南霉素的相对防效（80.60%）;苯并噻二唑的相对防效最高,达83.75%;氨基寡糖素和吗呱乙酸铜的相对防效相当,分别为71.72%和72.67%;超敏蛋白和盐酸吗啉胍的相对防效稍低,分别为68.55%和67.82%;啸克的相对防效最低,仅为44.78%。【结论】AHO对大田烟株番茄斑萎病毒属病毒病有很好的防控效果,其对番茄斑萎病毒属病毒病的效果优于部分市售药剂,具有开发成为防控番茄斑萎病毒属病毒病抗病毒剂的潜力。

| Abstract: | 【Objective】 The effect of plant- derived natural product 3- acetonyl- 3- hydroxyoxindole（ AHO） on tospovirus diseases was evaluated to provide scientific references for AHO to be developed into an antiviral agent.【Method 】5% AHO as well as seven commonly used antiviral agents such as harpin, amino oligosaccharins, moroxydine hydrochloride/triazole, moroxydine hydrochloride/cupric acetate, Ningnanmycin, XIAOKE and benzothiadiazole was sprayed on the tobacco leaves after the seedlings were transplanted. Then the incidence of tobacco plants was in-vestigated. 【 Result 】 The results showed that except XIAOKE, several other antiviral agents had a good control effect on tospovirus diseases after three-times continuous spraying. AHO had a control effect with the relative control effect of 79.86%, which was a little bit lower than that of ningnanmycin with the relative control effect of 80.60 %. Benzothiadiazole had the highest control effect, whose relative control effect was 83.75%. Amino oligosaccharins and moroxydine hydrochloride/triazole had an equivalent control effect, whose relative control effect was 71.72% and 72.67%respectively. The control effect of harpin and moroxydine hydrochloride/cupric acetate was lower than that of AHO,whose relative control effect was 68.55% and 67.82% respectively. However, the control effect of XIAOKE was the lowest, whose relative control effect was only 44.78%. 【Conclusion 】AHO has a better control effect on tospovirus dis-eases than most commercial pesticides, suggesting that it has the potential to be developed as an antiviral agent a gainst tospovirus diseases in the field. |
