Existence of color sextet diquark Higgs fields with TeV masses will indicate a fundamentally different direction for unification than conventional grand unified theories. One class of models where they appear naturally is the supersymmetric SU(2){sub L}xSU(2){sub R}xSU(4){sub c} model embedding the seesaw mechanism for neutrino mass with seesaw scale around 10{sup 11} GeV. The diquark Higgs fields in this model couple only to up-type quarks. We discuss phenomenological constraints on these fields and show that they could be detected at LHC via their decay to either tt or single top+jet. We also find that existing Tevatron data gives a lower bound on its mass somewhere in the 400-500 GeV, for reasonable values of its coupling.
