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 Additives on Weed Control of Difluosulfamide for Oat Fields
摘要
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.关键词
