Description Young and energetic pulsars can power strong pulsar wind nebula (PWN), which can be observed from radio to X-ray and beyond. Thanks to the superior sensitivity of the ASKAP EMU survey, we are able to identify new PWNe in the Galactic plane, and use them to guide our search of radio pulsars. This strategy was demonstrated successful by the recent discovery of a high dispersion measure (DM) pulsar powering a bow-shocked PWN with one of the longest tail. Recently, we analysed several EMU fields covering the Galactic plane and identified another four new PWNe candidates. Here we propose to use the Parkes UWL receiver to carry out targeted search of radio pulsars powering these PWNe. Since these system are located in the Galactic plane and can be distant, we expect them to have large DMs. Such high DMs will lead to strong scattering and smearing and make pulsars undetectable in previous pulsar surveys. The wide frequency coverage of UWL, especially the high frequencies, will allow us to avoid these effects and therefore offer us a better chance to find these pulsars.
