On a light clay soil, rich in OM, methabenzthiazuron at 4 kg/ha controlled Alopecurus myosuroides well in winter wheat and the control was maintained by sequential applications of chlortoluron at 1.375 kg/ha or isoproturon at 1.125. With single applications isoproturon at 2.25 kg/ha or 2 kg + dinoterb dimethyl amine at 1.81 kg/ha or + ioxynil-sodium at 0.415 kg + mecoprop-sodium at 0.974 kg/ha gave outstandingly good control of A. myosuroides. Best control of Galium aparine was obtained with metoxuron w.p. at 5 kg/ha and this led to the highest wheat yields.
