Figure 5 in Confirmation and differential metabolism associated with quinclorac resistance in smooth crabgrass (Digitorio ischoemum)

Figure 5. Amount of quinclorac (mg g−1 plant, mean ± SE) detected by liquid chromatography–diode array detector (DAD) in extracts of plants (aerial parts) from susceptible (SMT2) and two resistant (MSU1 and MSU2) Digitorio ischoemum populations, with previous application of 2 kg malathion ha−1 followed by 0.84 kg quinclorac ha−1 (QM), 0.84 kg quinclorac ha−1 (Q1X), no application of quinclorac or malathion (Q0X), and application of 2 kg malathion ha−1 alone (M), evaluated at 72 and 168 h after treatment (HAT). Means within an evaluation time and treatment with the same capital letter are not significantly different at the 5% level as determined by Fisher's protected least significant difference (LSD) test; means for the same population and evaluation time with the same letter are not significantly different at the 5% level as determined by the LSD test.
