| 摘 要： | 目的]筛选能有效防治中海拔地区烟草赤星病病害发生及危害的药剂。方法]设计6个不同施药处理与不施药空白对照,采用随机区组方法进行小区试验。结果]各药剂处理均对赤星病的发生和危害有一定的抑制作用,以戴琼脂帽Ⅱ（含10%宝利安0.1 g）效果最好,产量和产值较大,其次是戴琼脂帽Ⅰ（含10%宝利安0.3 g）和戴琼脂帽Ⅲ（含40%菌核净0.6 g）。且各施药处理对烟株农艺性状影响不大。结论]烟株打顶后戴含有10%宝利安0.1 g、10%宝利安0.3 g或含40%菌核净0.6 g的琼脂帽能有效抑制赤星病的发生和危害,提高收益,可进行一定面积的推广。

| Abstract: | Objective] The aim was to select the medicament what could effectively prevent and control the occurrence and damage of Alternaria alternate in middle elevation areas.Method] Six different pesticide treatments and non-pesticide blank control were designed,moreover,the method of randomized block was adopted to carry out plot experiment.Result] Every pesticide treatment had certain inhibiting effect on the occurrence and damage of Alternaria alternate,especially for agar cap Ⅱ(including 10% Bao Lee 0.1 g),the effects were best,moreover,acre yield and output value were larger,followed by agar cap Ⅰ(including 10% Bao Lee 0.3 g)and agar cap Ⅲ(including 40% dimethachlon 0.6 g).In addition,every pesticide treatment had little effect on tobacco agronomic traits.Conclusion] After topping,tobacco plants containing agar cap with 10% Bao Lee 0.1 g,10% Bao Lee 0.3 g or 40% dimethachlon 0.6 g could effectively prevent and control the occurrence and damage of Alternaria alternate,moreover,the yield could be improved,thus,the method can be popularized. |
