飞防助剂对双氟磺草胺防除燕麦田杂草的减量增效作用

Effect of flight control additive on reducing and increasing the quantity of difluosulfamide in weed control in oat field

  • 摘要:
    目的 评价2种飞防助剂对50%双氟磺草胺SC防除燕麦田杂草的减量增效作用。
    方法 采用植保无人机大疆T30茎叶喷施除草剂50%双氟磺草胺SC添加助剂防除燕麦田杂草。
    结果 试验结果表明,50%双氟磺草胺SC75 ml·hm−2,药后20 d、40 d对燕麦田杂草的株防效分别为60.38%和60.16%,40 d时对燕麦田杂草的鲜重防效为81.23%;50%双氟磺草胺SC67.5 ml·hm−2+迈飞180 ml·hm−2、50%双氟磺草胺SC60 ml·hm−2+迈飞180 ml·hm−250%、50%双氟磺草胺SC52.5 ml·hm−2+迈飞180 ml·hm−2、50%双氟磺草胺SC37.5 ml·hm−2+迈飞180 ml·hm−2处理药后40 d时对燕麦田杂草的株防效分别为72.31%、71.78%、70.44%、57.64%,对燕麦田杂草的鲜重防效分别为83.26%、81.26%、77.92%、62.54%;50%双氟磺草胺SC67.5 ml·hm−2+红雨燕180 ml·hm−2、50%双氟磺草胺SC60 ml·hm−2+红雨燕180 ml·hm−2、50%双氟磺草胺SC52.5 ml·hm−2+红雨燕180 ml·hm−2、50%双氟磺草胺SC37.5 ml·hm−2+红雨燕180 ml·hm−2处理药后40 d对燕麦田杂草的株防效分别为83.61%、78.28%、71.05%、54.98%,对燕麦田杂草的鲜重防效分别为91.43%、91.43%、87.43%、63.22%;
    结论 迈飞和红雨燕2种飞防助剂对50%双氟磺草胺SC防除燕麦田杂草具有明显的增效作用,两种助剂增效差异不明显。添加助剂180 ml·hm−1量后均可减少50%双氟磺草胺SC10%~30%的使用量,对燕麦表现安全,增产率在6.86%~10.81%。

     

    Abstract:
    Objective To evaluate the effect of two flight control additives on the control of weeds by 50% difluosulfamide SC in oat field.
    Methods Plant protection drone DJI T30 was applied to control weeds in oat field by spraying 50% difluosulfamide SC additive.
    Results The results showed that the plant control effect of 50% difluosulcham SC75ml·hm−2 on weeds in oat field was 60.38% and 60.16% after 20 and 40 days, respectively, and the fresh weight control effect on weeds in oat field was 81.23% at 40 days. 50% difluosulachlor SC67.5ml·hm−2+ Maifei 180 ml·hm−2, 50% difluosulachlor SC60ml·hm−2+ Maifei 180 ml·hm−2250%, 50% difluosulachlor SC52.5ml·hm−2+ Maifei 180 The plant control effects of ml·hm−2 and 50% difluosulchlor SC37.5ml·hm−2+ Maifei 180 ml·hm−2 on weeds in oat field 40d after treatment were 72.31%, 71.78%, 70.44% and 57.64%, respectively. The fresh weight control effects on weeds in oat fields were 83.26%, 81.26%, 77.92% and 62.54%, respectively. 50% difluosulchlor SC67.5ml·hm−2+ Red Swift 180 ml·hm−2, 50% difluosulchlor SC60ml·hm−2+ Red Swift 180 ml·hm−2, 50% difluosulchlor SC52.5ml·hm−2+ Red Swift 180 The plant control effects of ml·hm−1 and 50% difluosulchlor SC37.5ml·hm−2+ Red Swift 180 ml·hm−2 on weeds in oat field 40d after treatment were 83.61%, 78.28%, 71.05% and 54.98%, respectively. The fresh weight control effects on weeds in oat fields were 91.43%, 91.43%, 87.43% and 63.22%, respectively.
    Conclusion The two flight control AIDS Maifei and Hongyanyan have obvious synergistic effect on the control of weeds in oat field by 50% difluosulfamide SC, and the difference of synergistic effect between the two AIDS is not obvious. After adding 180mL/hm2, the amount of difluosulchlor SC10%-30% can be reduced by 50%, which is safe for oats, and the yield increase is 6.86%-10.81%.
