Fig. 2. TLC analysis of methanol extractable ¹⁴C. Disappearance of metolachlor over time (a) with curves representing nonlinear regression fits of the first-order equation. Symbols for (a) are • VBS metolachlor and BF metolachlor. Appearance of non-polar and polar metabolites are shown in (b). Symbols for (b) are • VBS non-polar, BF non-polar, VBS polar, and BF polar.
