为有效防控水稻纹枯病,开展了嘧菌酯·戊唑醇50%悬浮剂田间试验研究。采用38、75、112g(a.i.)/hm2 3个浓度兑水后进行田间喷雾,施药3次后第7d对水稻纹枯病平均防效分别为75.94%、85.69%、95.47%。经方差分析,供试药剂不同剂量处理间防效相比,差异显著,中剂量处理与对照药剂处理相比差异不显著,各药剂处理与空白对照相比差异均呈极显著。试验证明嘧菌酯·戊唑醇50%悬浮剂对水稻纹枯病具有较好的防治效果,且药后对水稻安全,在发病前施药效果更好,使用剂量以75~112g(a.i.)/hm2为宜。
為有效防控水稻紋枯病,開展瞭嘧菌酯·戊唑醇50%懸浮劑田間試驗研究。採用38、75、112g(a.i.)/hm2 3箇濃度兌水後進行田間噴霧,施藥3次後第7d對水稻紋枯病平均防效分彆為75.94%、85.69%、95.47%。經方差分析,供試藥劑不同劑量處理間防效相比,差異顯著,中劑量處理與對照藥劑處理相比差異不顯著,各藥劑處理與空白對照相比差異均呈極顯著。試驗證明嘧菌酯·戊唑醇50%懸浮劑對水稻紋枯病具有較好的防治效果,且藥後對水稻安全,在髮病前施藥效果更好,使用劑量以75~112g(a.i.)/hm2為宜。

The field experiment of Azoxystrobin.Tebuconazole 50% SC was carried out in order to control rice sheath blight. The concentration of 38, 75 and l12g (a.i.) /hm2 were separately sprayed for three sequent time and the control effect were 75.94%, 85.69% and 95.47%. There was significant difference between the treatment and the blank control. It was showed that 50% Azoxystrobin .Tebuconazole SC was effective in control of rice sheath blight. The recommended concentration is 75-112g (a.i.) /hm2.
