用 3%敌萎丹悬浮种衣剂按 1kg麦种拌药剂 1～ 3g有效成分对小麦出苗无影响 ,且对冬前分蘖和生长有促进作用。对小麦纹枯病的控制效果较为理想 ,表现为冬前效果显著 ,对病株率的防效 6 0 %～ 80 % ,从而有效地抑制了冬前发病高峰。敌萎丹处理区的病情指数显著低于对照区 ,亦显著低于对照药剂 15 %三唑酮可湿性粉剂 ,且最终产量较对照增加 2 7 34%～ 5 0 77%。 With 3% enemy Dan suspended seed coating agent 1kg wheat seed mixed with 1 ~ 3g active ingredient has no effect on the emergence of wheat, and tillering and growth before winter have a promoting effect. The control effect on wheat sheath blight is ideal, which shows that the effect before winter is significant, and the control effect on diseased plants is between 60% and 80%, thereby effectively suppressing the peak incidence before winter. The index of disease in the treatment of dizandan was significantly lower than that in the control area and significantly lower than the control agent 15% triadimefon WP, and the final yield was increased by 27.47% to 50.77% compared with the control.
