Figure 2 in Glufosinate enhances the activity of protoporphyrinogen oxidase inhibitors

Figure 2. Enhanced herbicidal activity with glufosinate and saflufenacil. Dose response for glufosinate (A) and saflufenacil (B) in Amaranthus palmeri. Isobole analysis for the combination between the two herbicides in different proportions (C). The graph shows the proportion of each herbicide to achieve 50% reduction in dry biomass (ED50). If no synergism had been observed for the two compounds, data points were expected to fall into the red dashed line (additive effect).The concave shape of the isobole curve indicates high levels of synergism between the two herbicides. Error bars represent the standard deviations of the means.
