Summary. In field experiments extending over the period 1964–68 wettable powder and water soluble formulations of asulam and M & B 8882 were applied to a range of grass species in summer and autumn. Phleum pratense L., Dactylis glomerata L., Holcus lanatus L., Agrostis tenuis Sibth. and Poa trivialis L. were more susceptible than Lolium perenne L., Festuca pratensis Huds. and Festuca rubra L., although effects were more persistent on H. lanatus than on the other species. Trifolium repens L. (white clover) was more resistant to M & B 8882 than to asulam, particularly in July. The pattern of selectivity was similar with summer and autumn treatment, but effects were slower to develop in the autumn.
