how to remove reflection of the floor

in New Users
I just creat a new primitive plane and use it for a floor but when i do the rendering the floor act like a mirror. How to remove this reflection ?

The primitive has by default a 3Delight surface, and the default settings "react" like shiny plastic when in Iray. So unless you want to apply an Iray surface shader, you could just go into the Surface tab, look for the "glossy" slider and dial that back to zero, or close to zero.
BeeMKay thank you !
