It is shown that spurious solutions are obtained when Runge-Kutta method is directly applied to the delay logistic equations with piecewiso continuous arguments. Runge-Kutta method which does not admit spurious solutions is constructed. The convergent order of this method is investigated. It is shown that this method is locally asymptotically stable and globally asymptotically stable under certain conditions.
