Current scenarios for the evolution of binaries predict that only 1% or less of the single radio pulsars in the galactic disk have been recycled in a binary. The fraction of such pulsars amongst the detected single radio pulsars is smaller than this. For magnetic field strengths [FORMULA] G the period vs. magnetic field diagram shows no evidence for injection of pulsars at [FORMULA] s. For magnetic field strengths [FORMULA] G recycled single pulsars cannot be discriminated from ordinary pulsars, i.e. there is no reason to assume that they are recycled.
