Prnum Pesticide(MFG) Commodity (Crop Group) Category (Code) EPA Status 14033 + METAMITRON ADAMA,BAYER BEET (GARDEN) (01AB = ROOT VEGETABLES SUBGROUPS) UNDER EVALUATION (06) Reasons for need: WEEDS. Pigweed species (AMAXX), common lambsquarters (CHEAL), other weed species. CHEAL needs PRE control options, AMAPA control demonstrated in sugar beet. There are few beet herbicides, they have narrow spectrums of control, and are often used at low rates, which can limit performance:06/25; NJ: Limited herbicide options for effective residual weed control in table beets grown in the Northeast region, with increasing presence of challenging herbicide-resistant (pigweed, ragweed) or troublesome (lambsquarters) weed species:09/25; OR:provides new herbicide option for beets and alternative to old chemistries currently used. It will also be a tool to control and mange herbicide-resistant weeds:08/26; Efficacy/Crop Safety (E/CS) Data Required: E/CS Research Comments: Comments: XH198 dmp only was converted to this new pr# 14033. Metamitron 24c labels exist for preemergence use in sugarbeets in parts of CO, ID, NE, OR and WY; EPA CAUTION:08/25; during the 2025 FUW, Adama supports as Potential: E/CS Before Approval for Residue:09/25/sb; Status changed to E/CS DATA ON-GOING 03/26/ds; Status updated to "Under Evaluation", preliminary E/CS data should be available before the FUW 06/26/ds; EPA Green:08/26; Field Res.Dir (FRD) Field ID# Field Data Track# Raw Data Data to MFG Performance Results & Comments Besancon, Thierry 26-NJP04 Brandenberger, L. 04-OK-DMP RECD 700.pdf 11.4 LB AI/A PRE; RELATIVELY SAFE, EQUAL TO PYRAZON; EQUAL CONTROL OF WEEDS (PIGWEED, GOOSEGRASS, CARPETWEED AND HENBIT), LOWER YIELD. Brandenberger, L. 04-OK-DMP RECD 738.pdf 1.4 AND 4.3 LB AI/A POST; RELATIVELY SAFE, EQUAL TO PHENMEDIPHAM; GENERALLY EQUAL CONTROL OF WEEDS (PIGWEED, GOOSEGRASS, CARPETWEED AND HENBIT) Besancon, Thierry 24-NJ-DMP RECD 5937.pdf 07/25 Metamitron (as a component of Terero) was PRE and/or POST to ‘Ruby Queen’ beets growing in a Honeoye loam. Metamitron was applied PRE at 1.46, 2.2, or 2.92 lb ai/a with and without s-metolachlor. Each metamitron PRE treatment was followed with a postemergence grower standard. Sequential metamitron treatments included 1.0 lb ai/a applied PRE with or without s-metolachlor followed by metamitron POST at 1.0 lb ai/a. Metamitron POST did not injure beets. Stunting from metamitron applied PRE without s-metolachlor ranged from 0 to 9% three weeks after planting (WAP). The addition of s-metolachlor with the higher rates of metamitron significantly increased crop injury 3WAP to 24 and 28%. All herbicide treatments provided excellent levels of weed cover reduction and yields were not statistically different across herbicide treatments. Sosnoskie, Lynn 23-NY-DMP RECD 5937.pdf 07/25 Metamitron (as a component of Terero) was PRE and/or POST to ‘Ruby Queen’ beets growing in a Honeoye loam. Metamitron was applied PRE at 1.46, 2.2, or 2.92 lb ai/a with and without s-metolachlor. Each metamitron PRE treatment was followed with a postemergence grower standard. Sequential metamitron treatments included 1.0 lb ai/a applied PRE with or without s-metolachlor followed by metamitron POST at 1.0 lb ai/a. Metamitron POST did not injure beets. Stunting from metamitron applied PRE without s-metolachlor ranged from 0 to 19% three weeks after planting (WAP). The addition of s-metolachlor with the two lower rates of metamitron significantly increased crop injury 3WAP, but was still only 16% or less. All herbicide treatments provided excellent levels of weed cover reduction and yields were generally equal across herbicide treatments. Miranda, Joshua 26-MIP06 RECD 6133.pdf 08/26 Metamitron (as Goltix 700SC) was applied PRE, POST, or sequentially PRE followed by POST at rates up to 2.92 lb ai/a (64 fl oz/a) to ‘Bohan’ garden beets growing in a Marlette fine sandy loam. Metamitron caused only minor, transient crop injury (0 to 5%) with no stand or yield reduction, performing comparably in crop safety and yield to the Dual Magnum + Nortron standard (which caused up to 8% early injury) and the weed-free control. All metamitron programs provided excellent pigweed and common lambsquarter control (~99%, outperforming Dual Magnum + Nortron's 90–96% control), though programs with sequential POST applications maintained better late-season foxtail control (77–88%) than PRE alone (63%), whereas Dual Magnum + Nortron provided the highest overall foxtail control at 96%. Becerra-Alvarez, Aaron 26-ORP20 RECD 6139.pdf 09/26 In a Corvallis, OR field trial, pre-emergence (PRE) and sequential post-emergence (POST with 1% v/v COC, applied 7–14 days apart) treatments of Goltix 700 SC (metamitron) at rates from 20.6 to 64 fl oz/A demonstrated crop safety with minimal injury (0–2 scale) and superior weed control (73–93% at 40 DAT) compared to the non-treated control (0%) and standard Dual Magnum + Nortron PRE treatment (55%), resulting in higher marketable beet yields up to 16 tons/A versus the standard's 7.5 tons/A. Yadav, Ram 26-OHP08 RECD 6141.pdf 09/26 Goltix 700 SC (metamitron) was applied PRE, POST, or sequentially as 1 PRE followed by 2 POST applications to garden beets between 20.6 and 64 fl oz/A and compared to Dual II Magnum + Nortron SC applied PRE at 16 + 60 fl oz/A. Metamitron treatments caused minimal to no crop injury with no reductions in beet stand, height, or yield, significantly outperforming the standard treatment, which caused severe crop injury, reduced stand counts, and lower marketable yield. While all metamitron programs provided poor control of annual grasses and common lambsquarter seedlings compared to the standard, sequential 1 PRE followed by 2 POST applications achieved good overall broadleaf weed control comparable to the standard. This sequential regime outperformed the moderate control from 3 POST applications, which exhibited poor control of emerging common purslane and redroot pigweed seedlings, and the poor broadleaf control from a single PRE application.
