Abstract
We present data for the QCD \ensuremath{\beta} function with two flavors of light Wilson fermions. We use the hybrid Monte Carlo algorithm and the method of matching of ratios of products of Wilson loops. At \ensuremath{\beta}=6/${\mathrm{g}}^{2}$=6.0 perturbative scaling has not yet set in, whereas at \ensuremath{\beta}=6.8 it clearly has. Since the matching is done for the integral of the \ensuremath{\beta} function this scaling is expected above \ensuremath{\beta}=6.0. .AE
