| 摘 要： | 拮抗球胞链霉菌AM6代谢产物田间试验结果表明,以含有AM6拮抗物质的液剂喷雾烟草叶片,可有效防治烟草赤星病。其防效随液剂中拮抗物质的含量的增加而升高,以100倍稀释防效最好,田间防效可达80.3%;施用次数2次为佳,平均防效达64.9%,病害发生严重时,可增施1次。同时,试验过程中发现含有AM6拮抗物质的液剂对烟草无明显药害。

| Abstract: | The field experiments showed that spraying the tobacco leaves with AM6 antifungal substance could effectively control the disease of brown spot. The effect of controlling the disease got better as the concentration of antifungal substance was high. The substance diluted 100 times has better controlling effect, the control effeciency is up to 80.3%. When it was applied at twice, the effect was much better, up to 65.1%. If the disease was serious, it was applied again. Meantime, it was not harmful for tobacco plant. |
