摘要
[目的]筛选对烟草叶枯病具有良好防治作用的生物农药。[方法]调查田间烟草叶枯病的发生和农艺性状。[结果] 0.3%四霉素AS 4.5 g a.i./hm^2+3%中生菌素WP 33.75 g a.i./hm^2+5%氨基寡糖素AS 112.5 g a.i./hm^2可有效控制病情蔓延,药后30 d对叶枯病防效达83.00%以上,且能有效促进烟株良好生长。[结论]该药剂组合可用于烟草叶枯病田间防控。
[Aims] The study aims to screen out effective biological fungicides against tobacco leaf blight. [Methods] The disease resistance and agronomic traits were analysised under field condition through random block design. [Results] The results showed that tetramycin 0.3% AS 4.5 g a.i./ha+mesophill 3% WP 33.75 g a.i./ha+amino-oligosaccharide 5% AS112.5 g a.i./ha could effectively control the spread of the leaf blight, the control effect on leaf blight was over 83.00% for 30 d after foliar spray. In addition, it could effectively promote the growth of tobacco plants. [Conclusions] The compound fungicide mentioned above could be used to control tobacco leaf blight.
