新型复配剂26%氟噻唑吡乙酮·双炔酰菌胺悬浮剂对番茄晚疫病的田间防效

Field Efficacy of New Mixtures of Oxathiapiprolin·Mandipropamid 26% SC against Tomato Late Blight

[目的]明确26%氟噻唑吡乙酮·双炔酰菌胺悬浮剂对番茄晚疫病的防治效果,为生产上应用提供理论依据。[方法]依照杀菌剂田间药效试验准则进行田间药效试验。[结果]根据2年试验结果,26%氟噻唑吡乙酮·双炔酰菌胺悬浮剂147、168 g a.i./hm22个处理的防效都高于2个对照药剂,其中168 g a.i./hm2处理的防效显著高于2个对照药剂,差异极显著。[结论]26%氟噻唑吡乙酮·双炔酰菌胺悬浮剂对番茄晚疫病具有较好的防治效果,建议使用剂量为147~168 g a.i./hm2。

[Aims] This study aims to clarify the control effect of oxathiapiprolin·mandipropamid 26% SC against tomato late blight, and provide the basis for security application in field. [Methods] The field trials were carried out according to guidelines for the field efficacy trials. [Results] According to the test results of two years, the control effects of the two treatments(147 and 168 g a.i./ha) of oxathiapiprolin·mandipropamid 26% SC was higher than the two control agents, and the control effect of 168 g a.i./ha treatment was significantly higher than those of the two control agents, and the difference was very significant. [Conclusions] Oxathiapiprolin·mandipropamid 26% SC has good control effect on tomato late blight. The recommended dose was 147-168 g a.i./ha in field.
