We study the third-harmonic generation by structured light in subwavelength silicon nanoparticles which support both electric and magnetic multipolar Mie resonances. By tailoring vectorial structure of pumping light, we may control strength polarization composition excited harmonic fields. In this way, generate nonlinear fields with radial or azimuthal polarizations addressing selectively a different type resonances, also enhancing suppressing optically induced response.
