Table 2 Shattercane dry weight as a percent of the nontreated control in response to ALS-inhibiting herbicides applied at labeled rates. Low numbers indicate greater reduction in growth. The experimental run x herbicide x population and the herbicide x population interactions were significant (p = 0.001), so data were analyzed by herbicide for each run. Each value represents the mean of four replications. The wild type is a susceptible sorghum line (Ck 60). Means in a row followed by the same letter are not statistically different, p = 0.05
