We report on a search for charge-1/3 third-generation leptoquarks (LQ) produced in pp collisions at {radical}(s)=1.96 TeV using the D0 detector at Fermilab. Third-generation leptoquarks are assumed to be produced in pairs and to decay to a tau neutrino and a b quark with branching fraction B. We place upper limits on {sigma}(pp{yields}LQLQ)B{sup 2} as a function of the leptoquark mass M{sub LQ}. Assuming B=1, we exclude at the 95% confidence level third-generation scalar leptoquarks with M{sub LQ}<229 GeV.
