| 摘要: |
| 速保利防治小麦白粉病保护作用显著，施用２５μｇ·ｍＬ-1的药液可使叶片不受白粉菌侵染。该药剂治疗作用良好，各病程施药均可铲除已发生的侵染，５０μｇ·ｍＬ-1的浓度即可达到治疗目的。该药剂有较长的持效期，用药量为种重的０．００５％～０．０１％时持效期为１５ｄ左右，０．０２％～０．０２５％时为２５ｄ，０．０３７５％时为３５ｄ． |

| Effect of Diconzole for Controlling Powdery Mildew(Erysiphe graminis f.sp. tritici) |
|
|
| Abstract: |
| The results of experiment with pot wheat seedling indicated that Dinicozonle had protective and curative activities against Erysiphe grarninis,application with 25
μｇ·ｍＬ-1 may prevent the infection by the pathogen;application with 50 μｇ·ｍＬ-1 may
eradicated the pathogen in defferent courses of disease from the infected wheat leaves.
The duration of effectiveness of seeds treated with 0.005%一0.01%,0.02%一0.0025%
and 0.0375%,was 15d.25d and 35d.respactively.The Dinicozonle inhibited the spores
germination,haustrum and secondary hyhae formation,and induced resistance from
wheat to Erysiphe graminis. |
