    Notes: 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.Sélectivité des herbicides a base de carbamate de benzène sulfonyle entre différentes espèces de graminées et le trèfle

    Notes: Summary The effect of weather factors before and after spraying on the activity of the herbicides isoproturon and clodinafop-propargyl was assessed in field experiments from 1997 to 2000. The herbicides were sprayed at four rates on eight to 15 occasions between October and April and efficacy was assessed as ED50 for the surviving panicles of Alopecurus myosuroides Huds. The ED50 values (N = normal dose) varied between 0.18 N and 1.16 N for isoproturon and 0.11 N and 1.51 N for clodinafop-propargyl. The effect of weather factors was investigated using multiple regression techniques for 1 to 14 days before and after spraying. These regressions were significant (P 〈 0.001) for each of the individual years. Between 86% and 97% of the total variation in response to both herbicides was accounted for, but the factors were not consistent from year to year. However, when the 3 years were combined for each herbicide the regression was also significant (P 〈 0.001) for isoproturon (78% variation accounted for) and for clodinafop-propargyl (72% variation accounted for). The current blanket advice, that the best control results from applications to small plants, was not always correct.
