Figure 4.

ACCase activities in four populations of D. ciliaris var. chrysoblephara after metamifop treatment. ACCase activities were determined using the ammonium molybdate spectrophotometric method. ACCase activities in resistant populations were less inhibited than in sensitive populations and also recovered to the same or even higher levels compared to untreated plants. Vertical bars indicate standard errors. Different lowercase letters indicate statistically significant differences (P < 0.05) based on Tukey’s tests.
