Figure 2

Lemna minor response (frond number) following a 7-d exposure to binary mixtures between nicosulfuron and terbuthylazine, according to the dose-level dependent IA model. The left-hand panel shows the agreement between experimental responses and those predicted by the model; the regression equation and corresponding coefficient are given embedded within the graph. The right-hand panel shows the isobologram illustrating the mixtures response surface as predicted by the model under a TU mixture strength scaling; the colour gradient is indicative of the level of effect, the graphical legend referring to frond number.
