Abstract: 【Objective】 The aim of present study is to screen out herbicide which might have better control effect on grass weeds such as avena fatua and setaria viridis of spring wheat field in order to provide guidance for scientific, safe and efficient use of the herbicides.【Method】 Randomized block design was used to research the number and the fresh weight of weeds at fixed spots, and the effect of herbicides on weeds and safety to spring wheat was evaluated.【Result】 After thirty days, the plant control effect and fresh weight control effect of 7.5% pyroxsulam WG 8.44, 11.25, 14.06 g/hm2, 30% mesosulfuron - methyl OD 45.00, 67.50, 90.00 g/hm2 and 70% flucarbazone WG 18.90, 25.20, 31.50 g/hm2 was 93.65%-100.00% and 97.55%-100.00% on grass weeds in spring wheat field, respectively. The plant control effect and fresh weight control effect of 69 g/L fenoxaprop-p-ethyl EW 82.80 g/hm2, 15% clodinafop - propargyl WP 67.50 g/hm2, 5% traxos EC 60.00 g/hm2and 3.6% mesosulfuron - methyl·iodosulfuron - methyl - sodium WG 10.80 g/hm2was 92.62%-97.88% and 95.66%-98.41% on grass weeds in spring wheat field, respectively. There was no significant difference between plant control effect and fresh weight e control effect of each treatment. All the treatments did not negatively influence the growth and development of the spring wheat.【Conclusion】 7.5% pyroxsulam WG 8.44, 11.25 g/hm2, 30% mesosulfuron - methyl OD 45.00, 67.50 g/hm2, 70% flucarbazone WG, 25.20 g/hm2, 69 g/L fenoxaprop-p-ethyl EW 82.80 g/hm2, 15% clodinafop - propargyl WP 67.50 g/hm2, 5% traxos EC 60.00 g/hm2and 3.6% mesosulfuron - methyl·iodosulfuron - methyl - sodium WG 10.80 g/hm2can effectively control grass weeds such as avena fatua and setaria viridis of spring wheat field. They are safe for the growth of spring wheat and can be used in field alternation reasonably.

摘要: 【目的】 筛选对春小麦田野燕麦、狗尾草等禾本科杂草具有较好防效的除草剂,为安全高效应用除草剂提供依据。【方法】 通过田间药效试验,采用随机区组的方法,定点取样调查各处理小区的杂草株数、鲜质量,评价供试药剂对春麦田杂草的防除效果及对春小麦的安全性。【结果】 药后30 d,7.5%啶磺草胺WG 8.44、11.25和14.06 g/hm2、30%甲基二磺隆OD 45.00、67.50和90.00 g/hm2和70%氟唑磺隆WG 18.90、25.20和31.50 g/hm2对春麦田禾本科杂草的株防效和鲜质量防效分别为93.65%~100.00%和97.55%~100.00%。69 g/L精噁唑禾草灵EW 82.80 g/hm2、15%炔草酯WP 67.50 g/hm2、5%唑啉·炔草酯EC 60.00 g/hm2和3.6%二磺·甲碘隆WG 10.80 g/hm2对春麦田禾本科杂草的株防效和鲜质量防效分别为92.62%~97.88%和95.66%~98.41%,各处理株防效和鲜质量防效之间均无显著性差异。各药剂处理对春小麦生长发育无异常影响,无药害。【结论】 7.5%啶磺草胺WG 8.44、11.25 g/hm2,30%甲基二磺隆OD 45.00、67.50 g/hm2,70%氟唑磺隆WG 18.90、25.20 g/hm2,69 g/L精噁唑禾草灵EW 82.80 g/hm2、15%炔草酯WP 67.50 g/hm2、5%唑啉·炔草酯EC 60.00 g/hm2和3.6%二磺·甲碘隆WG 10.80 g/hm2可有效防除春麦田野燕麦、狗尾草等禾本科杂草,且对春小麦生长安全,可在大田合理轮换使用。
