Evaluation of Very-Long-Chain Fatty Acid-Inhibiting Herbicides in Arkansas Rice Production
… The VLCFA-inhibiting herbicides 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 …

Herbicide safeners: upregulating detoxification mechanisms for selective weed management in grain sorghum (Sorghum bicolor L. Moench)
… grain sorghum when used with the PRE herbicide pyroxasulfone (Zidua®), a VLCFA inhibitor. A greenhouse study was first conducted to understand how pyroxasulfone affects grain sorghum emergence and seedling growth under controlled conditions, and to determine the efficacy of fluxofenim in …

Evaluation of Fenclorim Safener for Use in Rice with Group 15 Herbicides
… has demonstrated the utility of acetochlor and pyroxasulfone to provide in-season weed control for Arkansas rice production, but variable crop tolerance has been observed. Additionally, acetochlor at 1,260 g ai ha-1 elicited less rice injury when seeds were treated with a herbicide safener seed …

The Impact of Herbicide-Resistant Rice and Hybrid Rice Technology on Weedy Rice Evolution
… and RREC, Stuttgart, Arkansas. Application of pyroxasulfone (0.12 kg ha-1) in the fall fb 2,4-D (1.12 kg ha-1) 35 d pre-plant caused minimal (6%) crop injury and did not reduce yield. This treatment resulted in better control of volunteer rice (73%) than pyroxasulfone alone at 0.12 kg ha-1 …

Avoiding Protoporphyrinogen Oxidase Inhibiting Herbicide Selection Pressure on Common Ragweed and Palmer amaranth in Soybean
… near 100%. However, sulfentrazone combined with pyroxasulfone or pendimethalin provided similar control to flumioxazin. Acetochlor and linuron controlled common ragweed <74%, yet controlled Palmer amaranth >96%. Glufosinate applied POST controlled Palmer amaranth and common ragweed 74-100%, …

Characterization and Management of Acetolactate Synthase Inhibiting Herbicide Resistant Mouse-Ear Cress (Arabidopsis thaliana) in Winter Wheat
… with winter wheat. Results indicate flumioxazin, pyroxasulfone, and metribuzin can be used for effective PRE control whereas 2,4-D, dicamba, and metribuzin can be effective post control options. No mouse-ear cress interference with winter wheat was observed at density of more than 300 plants m-2.

Distribution and Control of Herbicide-Resistant Italian Ryegrass (Lolium perenne L. ssp. multiflorum Lam. Husnot) in Arkansas
… 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>

Influence of Cover Crop Termination Timing on its Volunteers and Weed Suppression
… that atrazine, isoxaflutole, metribuzin, and pyroxasulfone resulted in 92-94% control when applied preemergence. Similarly, atrazine and glyphosate provided 99% rapeseed control and glufosinate resulted in 89% control when applied postemergence. Therefore, volunteers can easily be controlled …

Characterization of HPPD-inhibitor resistance in waterhemp (Amaranthus tuberculatus)
… sulfentrazone, flumioxazin, metribuzin, and pyroxasulfone generally provided the highest levels of waterhemp control and greatest reduction in waterhemp density. Chapter 4 also includes a soil-applied mesotrione dose response comparing HPPD inhibitor-resistant waterhemp (MCR) and RxR progeny …

Mechanisms and control of waterhemp populations resistant to group 15 herbicides
… sensitivity to acetochlor, dimethenamid-P, pyroxasulfone, and S-metolachlor under greenhouse conditions. The research presented herein was initiated in 2018 to identify the resistance mechanism(s) within CHR and MCR/SIR to the VLCFA-inhibitor, S-metolachlor. Chapter 1 includes a literature …

Dissecting phenotypic inheritance of very-long-chain fatty acid inhibitor resistance in waterhemp (Amaranthus tuberculatus) using a novel greenhouse assay: 'PRIM'
… 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 importance and …

The Thin Green Line: A Framework for Evaluating the Invasive Potential of Bioenergy Crops
… under greenhouse conditions. The herbicides pyroxasulfone, sethoxydim and nicosulfuron may prove to be useful tools for the control of bioenergy crops if they escape cultivation. The potential for many of these exotic and highly competitive species to become invasive has hindered advancement …

Preemergence activity of chloroacetamide herbicides on a multiple herbicide-resistant population of waterhemp (amaranthus tuberculatus)
… non-encapsulated acetochlor, alachlor, and pyroxasulfone, which provided 75, 67, and 56% control, respectively, 28 days after treatment (DAT). Greenhouse dose-response experiments with S-metolachlor revealed a large difference in herbicide effective dose values between populations with …
