摘要

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
50%双氟磺草胺SC75 mL·hm⁻²，药后20、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SC 67.5 mL·hm⁻²+迈飞180 mL·hm⁻²、50%双氟磺草胺SC 60 mL·hm⁻²+迈飞180 mL·hm⁻²、50%双氟磺草胺SC 52.5 mL·hm⁻²+迈飞180 mL·hm⁻²、50%双氟磺草胺SC 37.5 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SC 67.5 mL·hm⁻²+红雨燕180 mL·hm⁻²、50%双氟磺草胺SC 60 mL·hm⁻²+红雨燕180 mL·hm⁻²、50%双氟磺草胺SC 52.5 mL·hm⁻²+红雨燕180 mL·hm⁻²、50%双氟磺草胺SC 37.5 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⁻²量后均可减少50%双氟磺草胺SC 10%～30%的使用量，对燕麦表现安全，增产率在6.86%～10.81%。

Abstract:
Objective
Effect of two additives specially designed for drone herbicide-spraying on weed control using difluosulfamide in oat fields was studied.
Methods
Two plant-safe additives, Maifei (MF) and Red Swift (RS), specially designed to be used on DJI T30 drone for spraying 50% difluosulfamide SC were applied at a rate of 180 mL·hm⁻² to evaluate their effects on reducing the count and fresh weight of weed plants in an oat field.
Results
The weed control effect indicated by the plant count reduction of the 75 mL·hm⁻² herbicide application was 60.38% after 20 d and 60.16% after 40 d, while the fresh weed weight reduction was 81.23% in 40 d. When 50% difluosulfamide SC was applied at a rate of 67.5 mL·hm⁻² along with MF or RS, the reduction on weed plant count of 72.31% for MF or 83.61% for RS, and that on fresh weed weight of 83.26% for MF or 91.43% for RS were achieved in 40 d. Under the application of 60 mL·hm⁻² herbicide with the additive, the weed plant count was reduced 71.78% for the added MF and 78.28% for RS, and the fresh weed weight decreased 81.26% for the added MF and 91.43% for RS. The 52.5 mL·hm⁻² herbicide and additive addition resulted in a weed plant count decline by 70.44% for MF and by 71.05% for RS and a fresh weight decrease by 77.92% for MF and by 87.43% for RS. When a 37.5 mL·hm⁻² herbicide was applied with the additive, the plant counts became 57.64% for MF and 54.98% for RS, and the fresh weight 57.64% for MF and 63.22% for RS lower than without the treatment.
Conclusion
Both MF and RS exerted a significant synergistic effect with the herbicide spray on weed control in the field. Moreover, it appeared that the application of difluosulfamide SC could be reduced by 10-30% while the oat yield increased by 6.86-10.81% through the safe addition of these additives.
