摘要
通过浸泡法测定了32.5%SC苯醚甲环唑·嘧菌酯对甘蔗凤梨病的防治效果。结果表明,在甘蔗下种期使用32.5%SC苯醚甲环唑·嘧菌酯1 500倍液浸泡蔗种茎5 min,对甘蔗凤梨病有较好的防治效果,防效为68.93%,显著优于25%SC嘧菌酯1 500倍液、50%WP多菌灵1 000倍液的。该药对蔗种安全、高效,是防治甘蔗凤梨病较为理想的新一代农药,使用剂量,以1 500倍为宜。
The control efficacy of 32.5% SC difenoconazole-azoxystrobin on sugarcane pineapple disease was evaluated in the fields. The results showed that the application of 1 500 times solution of 32.5% SC difenoconazole .azoxystrobin at the planting stage obtained a control efficacy of 68.93%, which significantly superior to that of the control agent, 1 000 times solution of 50% WP carbendazim. Our results also suggested that 32.5% SC difenoconazole-azoxystrobin could be used as a new efficient and safe fungicide for controlling sugarcane pineapple disease with the appropriate dose of 1 500 times solution.
