Figure 2

Survival (left) and biomass (right) of broom seedlings grown in soil previously treated with herbicides. Treatments were (a, b) metsulfuron, (c, d) terbuthylazine, (e, f) clopyralid, (g, h) hexazinone, (i, j) triclopyr (triangle), terbuthylazine/hexazinone mixture (filled circle) and triclopyr/picloram mixture (squares). Data are expressed as a proportion of untreated control plants, plotted against the time after herbicide application. The symbols show the measurements (triangles for low rates in a-h, filled circles for high rates in a-h). Curves were fitted to the data using the logistic model described in Equation 1.
