Bioavailability of metolachlor and glyphosate in aerobic and anaerobic soils
Metolachlor and glyphosate are two extensively used herbicides in the USA and throughout the globe. Despite the prevalence of anaerobic wet situations in the soil, the predictive capability for the environmental fate and bioavailability of these herbicides is based primarily on well-drained soil …

Differential tolerance of corn hybrids to metolachlor and its regulation by the safener benoxacor
… tolerance to the chloroacetanilide herbicide metolachlor and the thiocarbamate herbicide EPTC was examined in 11 corn hybrids. Tolerance to one of these herbicides does not imply similar tolerance to the other. Detoxication of these herbicides in plants is mediated via conjugation with …

Investigations on the mechanism of action of the oxime ether safeners for the protection of grain sorghum against metolachlor
… of metabolic enzymes which detoxify herbicides. Metolachlor at 10 μM and seed-applied CGA-133205 had no effect on germination while treatment with seed-applied oxabetrinil significantly reduced germination of grain sorghum. Results from experiments on ¹⁴C-acetate incorporation into lipids …

Mechanisms and control of waterhemp populations resistant to group 15 herbicides
… (CHR and MCR) with the VLCFA inhibitor S-metolachlor was much less than expected in field research. An alternative VLCFA-inhibiting herbicide, acetochlor, remained relatively effective. Additional research was conducted to investigate VLCFA-inhibitor efficacy on each population in the …

Development of sorption technology for the cleanup of pesticide contaminated wastewater
… adsorbent 572 for dicamba as Banvel 4L and metolachlor as Dual 8E under flow through conditions were three times higher than adsorptive capacities of Filtrasorb 400. Better performance of Ambersorb adsorbents under flow through conditions was likely the result of faster mass transfer …

Preemergence activity of chloroacetamide herbicides on a multiple herbicide-resistant population of waterhemp (amaranthus tuberculatus)
… reported with the chloroacetamide herbicide S-metolachlor. Similar observations were made on a separate waterhemp population from Champaign County, IL (CHR) with resistance to HPPD-, ALS-, PSII-, and PPO-inhibitors and 2,4-D. In both cases, another active ingredient from the same class, …
