不同除草剂复配异丙隆对小麦田多花黑麦草的田间防治效果OA
Field Efficacy of Co-Formulated Herbicides Containing Isoproturon Against Italian Ryegrass in Wheat Fields
探究小麦田多花黑麦草高效防除方案,筛选优势除草剂单剂及与异丙隆复配的协同增效作用,设置13组处理进行系统评估.结果表明:封闭效果防效最好的是35%砜吡草唑·吡氟酰草胺悬浮剂+50%异丙隆悬浮剂,其次为40%砜吡草唑悬浮剂+50%异丙隆悬浮剂、40%砜吡草唑悬浮剂、35%砜吡草唑·吡氟酰草胺悬浮剂和30%吡氟酰草胺·氟噻草胺悬浮剂+50%异丙隆悬浮剂等药剂,药后第104 d防效分别为99.23%、98.10%、97.30%、96.22%和80.23%;小麦越冬返青后,46.5%五氟·异丙隆悬浮剂+10%唑啉草酯乳油+50%异丙隆悬浮剂防效最好,其次为36%二氯异噁草酮悬浮剂+50%异丙隆悬浮剂和46.5%五氟·异丙隆悬浮剂+10%唑啉草酯乳油等药剂,药后第31d防效分别为98.02%、92.22%和80.73%.综上所述,防治小麦田杂草时,封闭药剂可选用35%砜吡草唑·吡氟酰草胺悬浮剂、40%砜吡草唑悬浮剂和30%吡氟酰草胺·氟噻草胺悬浮剂等药剂复配异丙隆使用,越冬后茎叶处理药剂选用46.5%五氟·异丙隆悬浮剂+10%唑啉草酯乳油、36%二氯异噁草酮悬浮剂药剂复配异丙隆可高效防治多花黑麦草,为小麦田杂草防治提供科学依据.
To explore the effective control strategies for Italian Ryegrass(Lolium multiflorum)in wheat fields,this study screened the dominant single herbicides and evaluated the synergistic of their mixture with isoproturon through a systematic assessment of 13 treatments.The results showed that,for pre-emergence soil treatment,the highest control efficacy was achieved with 35%pyroxasulfone·diflufenican suspension concentrate(SC)+50%isoproturon SC,followed by 40%pyroxasulfone SC+50%isoproturon SC,40%pyroxasulfone SC,35%pyroxasulfone·diflufenican SC,and 30%diflufenican·flufenacet SC+50%isoproturon SC.The control effects at 104 days after application were 99.23%,98.10%,97.30%,96.22%and 80.23%respectively.After wheat overwintering and regreening,the highest post-emergence control efficacy was obtained with 46.5%penoxsulam·isoproturon SC+10%pinoxaden emulsifiable concentrate(EC)+50%isoproturon SC,followed by 36%bixlozone SC+50%isoproturon SC,46.5%penoxsulam·isoproturon SC+10%pinoxaden EC and other agents.The control effects at 31 days after application were 98.02%,92.22%and 80.73%respectively.In summary,for weed controls in wheat fields,pre-emergence treatments can employ herbicides such as 35%pyroxasulfone·diflufenican SC,40%pyroxasulfone SC,and 30%diflufenican·flufenacet SC in mixture with isoproturon.For post-overwintering foliar applications,mixtures of 46.5%penoxsulam·isoproturon SC+10%pinoxaden EC and 36%bixlozone SC with isoproturon can efficiently control Lolium multiflorum.These results provide a scientific basis for weed control in wheat fields.
