Interaction in Model of Herbicide Combination Using Oxyfluorfen to Control Orchard Weeds
Oxyfluorfen을 주재(主材)로 한 과수원(果樹園) 제초제(除草劑) 조합처리(組合處理) 모형(模型)의 상호작용(相互作用) 효과(效果) 해석연구(解析硏究)
Abstract
The study was intended to analyze the interaction effects of paraquat and oxytluorfen as an orchard herbicide-mixture. Data were prepared from the former report of authors. The algebraic expression for the actions of paraquat and oxyfluorfen on the control percentages of peach orchard weeds, and their interactions were determined from the multiple regression polynomial and plotted in three-dimensional graphs. As a result of treatments by combination of paraquat and oxyfluorfen on the field which was dominated by perennial weeds, the most effective interactions were detected at combination rates of
