40%噻唑锌悬浮剂防治生姜细菌性叶枯病的田间防治效果评价
|
摘要
[目的]为了明确40%噻唑锌SC对生姜细菌性叶枯病的防治效果,为其在生姜上的推广和应用提供理论依据。[方法]采用喷雾法于发病初期进行田间试验。[结果]40%噻唑锌SC的3个剂量500、430、375 g a.i./hm2第3次药后7 d和第4次药后7 d的防治效果均高于90%,且对生姜没有药害。[结论] 40%噻唑锌SC对生姜安全,对生姜细菌性叶枯病具有很好的防效,建议使用剂量为375～430 g a.i./hm2。
[Aims] This study aims to determine the efficacy of zinc-thiazole 40% SC against bacterial leaf blight of ginger caused by Xanthomonas zingibericola n.sp.to provide a basis for disease control in ginger production.[Methods] Zinc-thiazole 40% SC was sprayed in ginger fields when ginger plants exhibited the early symptoms of bacterial leaf blight.[Results] The control efficacy of zinc-thiazole 40% SC were measured and compared at different dose of 500,430 and 375 g a.i./ha.The results showed that all treatments of zinc-thiazole 40% SC at these three doses displayed more than 90% control and no damage was observed to ginger plants.[Conclusions] The zinc-thiazole 40%SC is safe to use for ginger production,and it is effective in controlling bacterial leaf blight of ginger.The field recommended dose of zinc-thiazole 40% SC is 375-430 g a.i./ha.
