Summary. Trifluralin (2,6‐dinitro‐ NN ‐dipropyl‐4‐trifluoromethylaniline) pre‐sowing, and carbetamide ( d ‐ N ‐ethyl‐2‐(phenylcarbamoyloxy)propionamide) and asulam ( N ‐(4‐aminobenzenesulphonyl)methylcarbamate) pre‐sowing or post‐emergence were evaluated for the control of Rumex obtusifolius L. in autumn‐sown red clover ( Trifolium pratense L.). All herbicides gave good control of if. obtusifolius from seed. Asulam at 2 or 4 kg/ha gave the best control of R. obtusifolius from rootstocks, followed by trifluralin at 1 kg/ha and carbetamide at 2 kg/ha. Poa annua L. was controlled by trifluralin and carbetamide but not by asulam. The results are interpreted in terms of the mode of action and method of application of the herbicides.
