摘要
通过田间药效试验,评价5%唑啉草乳油(EC)对冬小麦田禾本科杂草的田间防治效果和安全性,确定最佳使用时期、使用方法与用量。结果表明,5%唑啉草酯乳油防除麦田禾本科菵草(Beckmannia syzigachne)和看麦娘(Alopecurus aequalis Sobol.)有较好的效果,以每公顷使用有效成分45.0~60.0 g为宜。施药适期为禾本科杂草3~5叶期效果最佳,喷雾法施药,每公顷对水450 L,可有效防除小麦田杂草。在试验剂量范围内所有参试药剂对小麦生长无不良影响,未发现对周围环境和试验区域内其他有益生物造成不利影响。
Through field efficacy tests,the field control effects and safety of 5% pinoxaden EC on winter wheat field grass weeds were evaluated,the optimal use period,method and dosage for the pesticide were determined.The results showed that the 5% pinoxaden EC had a good effect in controlling Alopecurus aequalis and Beckmannia syzigachne(Steud.)Fern.,and it was advisable to use effective components of 45.0~60.0 g per hectare.The suitable period of application was the best effect in the 3 to 5 leaf stage of grass weeds.Spraying with 450 litres of water per hectare can effectively control weeds in wheat fields.Within the test dose range,all test agents had no adverse effects on wheat growth,and no adverse effects were found on the surrounding environment and other beneficial organisms in the test area.
