  We present results from a deep search for radio emission from the X-ray
pulsar systems GX 1+4, GS 0834-430 and 4U 0115+63 which have variously been
suggested to possess radio jets and to be good candidates for propellor
ejection mechanisms. None of these sources is detected at their optical
positions, to 3 sigma limits of a few hundred micro-Jy. This places upper
limits on their radio luminosities and thus on the internal energy and numbers
of any relativistic electrons which are three to four orders of magnitude below
those of radio-bright X-ray binaries such as SS 433 and Cyg X-3. Spectral and
structural information on the proposed `radio lobes' of GX 1+4 make their
association with the source unlikely. The lack of detected radio emission from
any X-ray pulsar system is discussed statistically, and it is found that X-ray
pulsations and radio emission from X-ray binaries are strongly anti-correlated.
