We present data for the QCD {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 {beta}=6/{ital g}{sup 2}=6.0 perturbative scaling has not yet set in, whereas at {beta}=6.8 it clearly has. Since the matching is done for the integral of the {beta} function this scaling is expected above {beta}=6.0.
