| 摘 要： | 当前小麦阔叶除草剂品种繁多,各种除草剂防除麦田阔叶杂草效果差异较大。氯氟吡氧乙酸等几种麦田阔叶除草剂药效试验表明:200.0g/L氯氟吡氧乙酸在施药后30d,鲜质量防效和株防效分别达到78.4%和83.0%,持效期长,杀草彻底;56%二甲四氯钠+75%苯磺隆不同用药量和用水量以56%二甲四氯钠30.0g/667m2+75%苯磺隆1.5g/667m2对水30.0kg/667m2防效最高。建议:在以猪殃殃、婆婆纳等恶性杂草为主的麦田选用200.0g/L氯氟吡氧乙酸;在以播娘蒿、荠菜、遏蓝菜等杂草为主麦田,选用56%二甲四氯钠+75%苯磺隆。另外为避免杂草产生抗药性,56%二甲四氯钠+75%苯磺隆、22%唑草酮+14%苯磺隆、40%唑草酮+10%苯磺隆可交互使用。

| Abstract: | Broadleaf herbicide in wheat field has several kinds in recently,but the control result was difference among them.The results showed that the emergence and weight defend could get 78.4% and 83.0% with 200.0 g/L fluroxypyr's effect level after 30 days,control period and efficacy of broadleaf herbicide were long and good.The treatment method from 1st to 3nd in which the best efficacy was the 1st.We proposed that 200.0 g/L fluroxypyr may control cleavers and the genus veronica,56% MCPA-Na and 75% tribeur may c... |
