摘要： 为了探索50g/L唑啉草酯防除冬大麦田虉草最佳用量和时期，采用50g/L唑啉草酯EC（爱秀）900~2400mL/hm24个用量进行小区试验，防除冬大麦田虉草。结果表明最佳施药时间为虉草3~4叶期，大麦4~5叶期，此时施药防除效果最好，4个用量防效均达到97%以上。50g/L唑啉草酯EC（爱秀）对麦田虉草具有较好的防治效果，显著优于对照药剂69g/L精噁唑禾草灵EW（大彪马）及人工除草。在大麦4~5叶期，虉草3~4叶期时施药，当用量达到900~1200mL/hm2，防效可达到97%以上。50g/L唑啉草酯EC（爱秀）用于冬大麦田虉草防除没有观察到对田间节肢动物的不良影响，对大麦安全，没有产生药害。

Abstract: The study aim was to explore the optimal dose and application time of pinoxaden in the control of Phalaris arundinacea in barley field. In the plot experiments, four doses (from 900 to 2400 mL/hm2) of pinoxaden (50 g/L) EC was applied for the control of P. arundinacea in barley field. The optimal application time of pinoxaden was 3- 4 leaf stage of P. arundinacea and 4- 5 leaf stage of barley. In this stage of P. arundinacea, the control efficacy of four doses was all more than 97% . The 50 g/L pinoxaden exhibited excellent efficacy to P. arundinacea, and the efficacy was better than that of the 69 g/L fenoxaprop-p-ethyl and manual weeding. In 4-5 leaf stage of barley and 3-4 leaf stage of P. arundinacea, when the pinoxaden was applied at the dose from 900 to 1200 mL/hm2, the efficacy for controlling P. arundinacea could be more than 97%. There was no harmful effect to other arthropods in field, and it was safe to barley.
