  Previous research has shown that the peak of the quarkonium entropy at the
deconfinement transition would be related to the entropic force which induces
the melting of quarkonium. In this article, we study the effect of backreaction
on the entropic force in a strongly coupled plasma of adjoint matter. The
backreaction covered here comes from the presence of static heavy quarks evenly
distributed over such a plasma. It is found that the inclusion of backreaction
increases the entropic force thus enhancing the quarkonium dissociation, in
accord with the findings of the imaginary potential.
