摘要
探讨了2,4-D丁酯、扑草净、单嘧磺隆对谷子田杂草的防除效果,田间试验结果表明:扑草净质量浓度为1200g/hm2的防效超过80%,为防除马齿苋的最佳除草剂处理;扑草净质量浓度为1200g/hm2和单嘧磺隆质量浓度为600g/hm2的防效超过80%,为防除反枝苋的最佳除草剂。
This paper observed the weed control efficacy of 2,4-D,prometryne and monosulfuron in millet.The experiments indicated that at the mass concentration of 1 200 g/hm2,the control efficacy of prometryn is beyond 80%,it is the best treatment to control portulaca oleracea L.The control efficacy of prometryn(1 200 g/hm2) and monosulfuron(600 g/hm2) is beyond 80%,it is the best treatment to control Amaranthus retroflexus L.
