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 …

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, …

Evaluation of Very-Long-Chain Fatty Acid-Inhibiting Herbicides in Arkansas Rice Production
… pethoxamid, pyroxasulfone, acetochlor, and S-metolachlor were evaluated for rice tolerance and control of commonly problematic weeds in Arkansas rice at various rates and application timings. Pyroxasulfone and S-metolachlor were deemed unfit for use in rice production because of negative …

Dissecting phenotypic inheritance of very-long-chain fatty acid inhibitor resistance in waterhemp (Amaranthus tuberculatus) using a novel greenhouse assay: 'PRIM'
… literature review of the Group 15 herbicides, S-metolachlor, and pyroxasulfone. Their developmental history, mode of action, selectivity in weedy plants, edaphic impacts, and agronomic importance in row crop cultivation are discussed. Herbicide resistance in waterhemp, including its agronomic …

Distribution and Control of Herbicide-Resistant Italian Ryegrass (Lolium perenne L. ssp. multiflorum Lam. Husnot) in Arkansas
… the residual herbicides flumioxazin plus S-metolachlor, S-metolachlor, clomazone, and pyroxasulfone applied immediately following fall tillage reduced Italian ryegrass biomass by 83 to 95% at 200 days after treatment.</p>

Managing Cereal Rye Living Mulch in Snap Beans with Chemical Mowing and Preemergence Herbicides
… Cereal rye tolerated the low-label rate of S-metolachlor, dimethenamid-p, pendimethalin, and EPTC applied preemergence. These results will inform the methodologies of future studies examining cereal rye living mulch use in vegetable systems.

Soybean Response and Weed Control With Flumioxazin, and Sorption, Degradation, and Weed Control With Isoxaflutole
… of isoxaflutole rates were tank-mixed with S-metolachlor/atrazine to compare velvetleaf density, weed control, corn injury, and corn yield. Herbicide applications were made at three different timings: early preplant, preplant incorporated, and preemergence. The environmental fate of …

Synthese von planar chiralen Imidazoliumsalzen, ihren Metall-Carbenkomplexen und deren Verwendung in der asymmetrischen Katalyse
… including the preparation of the herbicide (S)-metolachlor, which is obtained through an asymmetric hydrogenation reaction mediated by a ferrocenyldiphosphane. [2.2]Paracyclophanes constitute another important class of planar chiral substances, which are also established as ligands in asymmetric …

New Herbicide Strategies for Weed Management in Pumpkin and Soybean and Potato Vine Desiccation
… injury (34 to 39%) 14 days after planting. S-metolachlor controlled weeds similar to acetochlor without significant injury. Palmer amaranth has developed resistance to six different herbicide modes of action. The weed grows rapidly and is best controlled <10 cm in height. To control glyphosate …

Evaluation of Weed Management and the Agronomic Utility of Cotton Grown on a 15-Inch Row Configuration and the Biology and Ecology of Doveweed
… or pyrithiobac applied preemergence (PRE), S-metolachlor or pyrithiobac mixed with glufosinate applied MPOST, or trifloxysulfuron applied late postemergence (LPOST) to 11-leaf cotton. In 2005, glufosinate alone applied EPOST and MPOST did not adequately control annual grasses and Amaranthus …

Herbicide safeners: upregulating detoxification mechanisms for selective weed management in grain sorghum (Sorghum bicolor L. Moench)
… to compare the effects of pyroxasulfone to S-metolachlor (Dual Magnum®; a different VLCFA inhibitor) applied PRE in grain sorghum, with or without fluxofenim. Results indicated that pyroxasulfone provides greater weed control compared to S-metolachlor. However, as weed control increases, crop …
