If the parameter tan{beta} of the minimal supersymmetric model is large, then b and {tau} Yukawa interactions are important. These can significantly modify the masses and decays of sparticles. We describe new calculations which allow a reliable exploration of large tan{beta} values, and discuss implications for collider experiments. For large values of tan{beta} , charginos and neutralinos may dominantly decay to {tau} leptons or b quarks. The usual cross sections for multilepton signatures may be greatly reduced, but supersymmetry may be detectable via new signals involving {tau} {close_quote}s or b {close_quote}s in the final state. {copyright} {ital 1997} {ital The American Physical Society}
