Abstract Limits on charged-scalar Yukawa couplings from tau and B decays are discussed. They (and other existing limits) are consistent with ''strong'' couplings (approx. =1 for the third generation) even if the lightest scalar mass is in the range 20approx. <M/sub phi/approx. <100 GeV but saturated in this case. B(B..-->..tau..nu..X) and (for M/sub phi/>m/sub t/)B(T..-->..tau..nu..X) may be then as large as 30% and 70%, respectively. Both for M/sub phi/<m/sub t/ and M/sub phi/>m/sub t/ the potentially possible top-quark signature in pp-bar collisions is (tau+2 jets) final state. The upper limit for tau..--> nu..eta..pi.. is approx. =0.003%.
