Stimulated scattering of radio emission by ultrarelativistic electron-positron plasma filling a pulsar magnetosphere is considered. In the presence of background radiation, the scattering from a beam into the background dominates over scattering into the beam. It is shown that this process may be important at frequencies ≤ 100 MHz and may give rise to low-frequency turnovers in pulsar spectra.
