摘要
[目的]探讨42.4%唑醚·氟酰胺悬浮剂对番茄叶霉病的田间防治效果.[方法]以10%苯醚甲环唑水分散粒剂和70%甲基硫茵灵可湿性粉剂为对照药剂,采用小区试验研究42.4%唑醚·氟酰胺悬浮剂对番茄叶霉病的防治效果.[结果]42.4%唑醚·氟酰胺悬浮剂在剂量为150.0~225.0 g a.j./hm2时,对番茄叶霉病的防治效果为83.37% ~ 91.63%,与10%苯醚甲环唑水分散粒剂120.0ga.i./hm2对番茄叶霉病的防治效果无显著差异,但显著高于70%甲基硫菌灵可湿性粉剂562.5 g a.i./hm2的防治效果.[结论]42.4%唑醚·氟酰胺悬浮剂可广泛用于番茄叶霉病的防治.
Abstract
[Objective] The control effect of pyraclostrobin + fluxapyroxad 42.4% SC against tomato leaf mould was discussed.[Method] Taking difenoconazole 10% WG and thiophanate-methyl70% WP as control agents,the control effect of pyraclostrobin + fluxapyroxad 42.4%SC against tomato leaf mold was studied by the method of plot experiment.[Result] The control effect of pyraclostrobin + fluxapyroxad 42.4% SC applied at the doses of 150.0-255.0 g a.i./hm2 against tomato leaf mould in the field was 83.37%-91.63%.The control efficiency was equal to 10% difenoconazole WG at the dose of 120.0 g a.i./hm2,but was more significant than that of thiophanate-methyl 70% WP at the dose of 562.5 g a.i./hm2.[Conclusion] Pyraclostrobin + fluxapyroxad 42.4% SC can be widely used for control of tomato leaf mould.
