  Upcoming neutrino telescopes promise a new window onto the interactions of
neutrinos with matter at ultrahigh energies ($E_\nu = 10^7$-$10^{10}$ GeV), and
the possibility to detect deviations from the Standard Model predictions. In
this paper, we update previous predictions for the enhancement of the
neutrino-nucleon cross-section for motivated leptoquark models and show the
latest neutrino physics bound, as well as analyse the latest LHC pair
production and Drell-Yan data, and flavour constraints (some of which were
previously missed). We find that, despite the next generation of neutrino
experiments probing the highest energies, they will not be enough to be
competitive with collider searches.
