“…There are no published studies reporting injury from pyroxasulfone in corn and Sikkema et al (2008) reported that pyroxasulfone was safe to a number of sweet corn hybrids. Oftentimes sweet corn hybrids have less tolerance to herbicides than field corn.…”

Field studies were conducted in Knoxville, TN, over a 2-yr period (2007 and 2008) to determine the field dissipation rate and efficacy of pyroxasulfone, acetochlor, dimethenamid, ands-metolachlor to broadleaf signalgrass. Depending on rainfall patterns, pyroxasulfone at 209 g ai ha−1provided broadleaf signalgrass control of > 75%, which was equal to or superior to acetochlor at 1,740 g ai ha−1, dimethenamid at 1,500 g ai ha−1ands-metolachlor at 1,420 g ai ha−1. Pyroxasulfone provided residual control into the growing season and provides a tool for resistance management of later-emerging weeds. Herbicide dissipation was rapid in all soils (half-life usually < 20 d), although it was slower in a dry year. The order of herbicide dissipation and half-life in days in the 2 yr was acetochlor (3.5, 5 d) > dimethenamid (5, 9 d) >s-metolachlor (8.8, 27 d) > pyroxasulfone (8.2, > 71 d). There was poor correlation between observed weed control at 45 d after treatment and chemically determined herbicide concentrations at that same time, with ∼ 40% difference in 2007 and ∼ 50% difference in 2008.

“…Odero and Wright (2013b) reported no injury to sweet corn with pyroxasulfone applied at up to 1,000 g ha– 1 on fine-textured soil with 80% organic matter. Sikkema et al (2008) reported tolerance of several sweet corn hybrids to pyroxasulfone at 209 and 418 g ha– 1 on fine-textured soils with 3.7% to 9.2% organic matter. The HPPD-inhibitor herbicides mesotrione, topramezone, and tembotrione did not cause sweet corn injury in either growing season.…”

“…In contrast, Odero and Wright (2013b) reported that pyroxasulfone at 214 g ha −1 provided effective weed control in soils with 80% organic matter. Tolerance of sweet corn to pyroxasulfone with minimal transient phytotoxicity has been reported (Odero and Wright 2013b; Sikkema et al 2008). Pyroxasulfone is marketed as a solo product (Anonymous 2021b) or as a premix with herbicides that inhibit protoporphyrinogen oxidase, such as carfentrazone-ethyl or fluthiacet-methyl (Anonymous 2021a).…”

Preemergence and postemergence weed control in sweet corn on organic soils

et al. 2023

View full text Add to dashboard Cite

Alternative weed management programs are needed for sweet corn on organic soils in the Everglades Agricultural Area (EAA) in southern Florida, which is reliant mostly on atrazine and S-metolachlor. Field experiments were conducted in 2021 and 2022 to evaluate the efficacy of pyroxasulfone (183 and 237 g ha-1) alone or as a premix with carfentrazone-ethyl (13 and 17 g ha-1) or fluthiacet-methyl (6 and 7 g ha-1), S-metolachlor (1,790 g ha-1) alone or in combination with atrazine (3,360 g ha-1) applied preemergence (PRE); mesotrione (105 g ha-1), topramezone (25 g ha-1), and tembotrione (92 g ha-1) applied postemergence (POST) alone or in combination with atrazine (560 and 2,240 g ha-1) or bentazon (1,120 g ha-1); and mechanical cultivation alone at the fourth and the fourth followed by the sixth leaf stages of sweet corn. Preemergence-applied herbicides did not provide acceptable fall panicum, common lambsquarters, and common purslane control probably due to lack of incorporation into the soil because of limited rainfall. Postemergence topramezone alone or in combination with atrazine or bentazon resulted in effective fall panicum control (>91%). Topramezone alone provided 83% and 88% common lambsquarters and common purslane control, respectively, whereas addition of atrazine to topramezone resulted in >94% control of both weed species. Mesotrione and tembotrione plus atrazine provided excellent control (>93%) of both broadleaf weed species but poor fall panicum control (<72%). Mechanical cultivation alone did not effectively control any weeds. Overall, topramezone treatment programs resulted in higher sweet corn yield. These results show that combining topramezone, mesotrione, and tembotrione with atrazine improved broadleaf weed control. Fall panicum control was only improved with the combination of topramezone with atrazine showing that atrazine is an important mixture component of these herbicides to provide effective postemergence weed control in sweet corn on organic soils of the EAA.

“…Tolerance to pyroxasulfone has been widely reported in annual crops (Kurtenbach et al 2019;McNaughton et al 2014;Sikkema et al 2008) and in the propagation of sweet potatoes (Ipomea batatas L.) (Smith et al 2019). Hazelnuts displayed a high level of tolerance to pyroxasulfone applied shortly after transplanting.…”

Hazelnut hectarage is expanding in Oregon. Weed competition in young orchards can severely reduce the growth and survival of plants. New orchards replace crops, including grass seed fields, which often are infested with herbicide-resistant weeds, including Italian ryegrass. This research evaluated hazelnut tolerance to pronamide, pyroxasulfone, and S-metolachlor. Three multi-year field experiments were conducted at newly-planted orchards in the Willamette Valley during 2019 and 2020. Treatments compared pyroxasulfone (0.24 kg ai ha-1), pronamide (2.08 kg ai ha-1), and S-metolachlor (1.39 kg ai ha-1) applied at the reference rate, two- and four-fold compared to weed-free check. Treatments were applied within two weeks after the winter transplant and reapplied the following year. Hazelnuts showed a high tolerance to all herbicides tested, with negligible injury noted (<3%). No changes in leaf chlorophyll were noted, averaging 242, 179, and 225 mg m-2 on each study site. Tree growth was similar among treatments as measured by trunk cross-sectional area, canopy volume, and internode length. A separate study evaluated the control of Italian ryegrass. Pronamide and pyroxasulfone provide 100% control of Italian ryegrass, and weed dry weight was reduced by up to 79 % compared to the grower standard. This study documents that hazelnuts are tolerant to pronamide, pyroxasulfone, and S-metolachlor, and that these herbicides can improve weed management in young orchards.
