Figure 1 in Confirmation and differential metabolism associated with quinclorac resistance in smooth crabgrass (Digitorio ischoemum)

Figure 1. Visual control of susceptible and resistant Digitorio ischoemum crabgrass at 28 d after treatment. The crabgrass was at the three-leaf stage of growth when herbicide was applied. Control was visually assessed on a 0%–100% scale (0% = no plant death; 100% = complete plant death). The data were normalized relative to the nontreated control. Error bars show the standard error of the mean. R, resistant; S, susceptible.
