摘　　要：采用32．5％阿米妙收悬浮剂4种不同稀释倍数与常规药剂对甘蔗凤梨病进行田闻药效对比试验。结果表明，32．5％N米妙收悬浮剂处理对甘蔗风梨病防效随施用浓度（量）的增加而提高，甘蔗的萌芽率与防效成正相关。32．5％阿米妙收悬浮剂1000倍液、1500倍液对甘蔗凤梨病防效达32．10％39．63％，明显优于常规药剂；32．5％阿米妙收悬浮剂1000倍液、1500倍液及2000倍液处理甘蔗的萌芽率达60-24％以上，高于常规药剂，达到大田生产指标。建议32．5％阿米妙收悬浮剂使用浓度以1000-1500倍液为宜。Four different concentrations of 32.5% Amistar Top SC and conventional fungicide （CK） were used to control sugarcane pineapple disease in field. The results showed that control effect of sugarcane pineapple disease gradually increased with increasing 32.5% Amistar Top SC concentrations, and there was positive correlation between the germination rate and control effect. The control effect of 1000 and 1500 times Amistar Top SC was up to 32.10%-39.63%, significantly higher than that of conventional fungicide. The germination rate of 1000, 1500 and 2000 times Amistar Top SC was up to 60.24%, higher than that of the control. Recommendation on applying concentration of 32.5% Amistar Top SC was as 1000-1500 times in field.
