Figure 4. Specific glutathione S-transferase activity changes toward 1 in Confirmation and differential metabolism associated with quinclorac resistance in smooth crabgrass (Digitorio ischoemum)

Figure 4. Specific glutathione S-transferase activity changes toward 1-chloro-2,4- dinitrobenzene in Digitorio ischoemum tissues after (A) 0.84 kg quinclorac ha−1 or (B) 7.56 kg quinclorac ha−1. Data were expressed as a percentage change of the nontreated. Values are presented as mean ± SE. Error bars indicate the standard error of the mean. R, resistant; S, susceptible.
