“…Vetch response was variable in that it had the most sensitivity to herbicide carryover of all the broadleaf plants with all but one herbicide effecting stand establishment in 2016-17; however, it did not exhibit a stand reduction the following year. Some studies have shown hairy vetch to be the most tolerant cover crop to herbicide carryover, whereas other studies showed it to be the most sensitive (Bryan 2014;Hartzler and Anderson 2015;Rogers et al 1986;Stahl 2016;Yu et al 2015). Palhano et al (2018) found clover had reduced biomass in a field study from residual herbicides but emergence reductions were not observed, whereas the opposite occurred in this study.…”

“…Vetch had significant stand reductions for all herbicide treatments, except for prometryn, at 48 to 52 DAP, ranging from 14% to 80% over both locations. The sensitivity of vetch to residual herbicides was not observed in two previous studies that evaluated corn and soybean herbicides (Bradley et al 2016;Yu et al 2015). However, two other studies found significant vetch injury or biomass reductions, indicating that environmental or soil composition factors are likely playing a role in herbicide carryover effecting vetch establishment (Bryan 2014;Palhano et al 2018).…”

“…Producers often use residual herbicides during the growing season to extend the period of weed control and provide another control method to herbicide programs especially to manage herbicide-resistant weeds. However, residual herbicides can prevent the successful establishment of fall-seeded cover crops, thus reducing biomass and subsequent weed suppression and achieving longer-term benefits provided by cover crops (Curran et al 2006;Rogers et al 1986;Yu et al 2015).…”

Cover crop response to residual herbicides in peanut-cotton rotation

Cover crops can provide many benefits to peanut and cotton crops planted in rotation including suppressing weeds, conserving soil moisture after termination, increasing soil organic matter, and reducing soil erosion. However, herbicide carryover can affect cover crop establishment. The objective of this study was to investigate the responses of 6 cover crops (daikon radish, cereal rye, oat, crimson clover, winter wheat, and common vetch) to 12 soil residual herbicides. A multiyear (2016–2018), multilocation study was conducted in Macon and Henry counties, Alabama. Herbicide treatments included S-metolachlor, acetochlor, pyroxasulfone, diclosulam, imazapic, chlorimuron-ethyl, bentazon plus acifluorfen, pyrithiobac-sodium, trifloxysulfuron-sodium, diuron, prometryn, and flumioxazin, each applied at 10% of the full-labeled rate. At 42 to 52 and 145 to 149 d after planting (DAP), cover crop plant heights and stand counts were evaluated, as was biomass at 145 to 149 DAP. Treatments varied from year to year but not locations. In 2016, significant stand reductions (P ≤ 0.10) of 36% to 43% in rye and 44% to 75% in wheat were observed at 48 to 52 DAP for S-metolachlor, acetochlor, pyroxasulfone, imazapic, and bentazon plus acifluorfen compared with nontreated plants. Vetch had stand reductions ranging from 14% to 80% for all treatments 50 DAP except for plants treated with prometryn. S-metolachlor, pyroxasulfone, and acetochlor reduced stands of rye, wheat, and vetch more than any other herbicides. In 2017, at 147 to 149 DAP, clover stands were reduced by 29% with diclosulam and by 38% with trifloxysulfuron-sodium. Similarly, radish stands were reduced by 64% with diclosulam treatment. No significant biomass reductions were observed for any cover crop species either year. Oat showed the most tolerance with no treatments reducing any growth parameters either year. Although initial injury and stunting may occur, biomass at termination of cover crops were not affected by herbicide residues evaluated in this study.

“…MES can persist in the soil up to 32 days after application depending on the environmental conditions and type of soil (Dyson et al 2002). Its residues affect several sensitive crops, such as snap beans, pickling cucumber, cabbage and pepper (Yu et al 2015). Moreover, it was shown that the AMBA had a higher toxicity than the parent compound (Barchanska et al 2014; Bonnet et al 2008).…”

The aim of this study was to monitor the sediment, soil and surface water contamination with selected popular triketone herbicides (mesotrione (MES) and sulcotrione(SUL)), atrazine (ATR) classified as a possible carcinogen and endocrine disrupting chemical, as well as their degradation products, in Silesia (Poland). Seventeen sediment samples, 24 soil samples, and 64 surface water samples collected in 2014 were studied. After solid-liquid extraction (SLE) and solid phase extraction (SPE), analytes were determined by high-performance liquid chromatography (HPLC) with diode array detection (DAD). Ten years after the withdrawal from the use, ATR was not detected in any of the collected samples; however, its degradation products are still present in 41 % of sediment, 71 % of soil, and 8 % of surface water samples. SUL was determined in 85 % of soil samples; its degradation product (2-chloro-4-(methylosulfonyl) benzoic acid (CMBA)) was present in 43 % of soil samples. In 17 % of sediment samples, CMBA was detected. Triketones were detected occasionally in surface water samples. The chemometric analysis (clustering analysis (CA), single-factor analysis of variance (ANOVA), N-Way ANOVA) was applied to find relations between selected soil and sediment parameters and herbicides concentration. In neither of the studied cases a statistically significant relationship between the concentrations of examined herbicides, their degradation products and soil parameters (organic carbon (OC), pH) was observed.Electronic supplementary materialThe online version of this article (doi:10.1007/s11356-016-7798-3) contains supplementary material, which is available to authorized users.

Residual herbicides can cause injury to a future crop. Residual herbicides applied to soybean [Glycine max (L.) Merr.] or winter wheat (Triticum aestivum L.) may impact cover crops seeded in the same growing season. The objective of this study was to determine the effect of residual herbicides on oilseed radish (Raphanus sativus L.) establishment and growth after 10 postemergence (POST) broadleaf herbicides were applied in winter wheat and 12 preemergence (PRE) and 7 POST herbicides were applied in soybean. Oilseed radish injury was assessed 14 and 28 d after emergence (DAE) and stand density and biomass were measured 28 DAE. Residual herbicides used for broadleaf weed control in winter wheat caused less than 5% oilseed radish visible injury and there was no reduction in stand density and biomass. In soybean, imazethapyr applied PRE caused 43% and 48% oilseed radish injury at 14 and 28 DAE, respectively. There was no decrease in oilseed radish stand density and biomass. Imazethapyr applied POST to soybean caused 47% and 59% oilseed radish injury at 14 and 28 DAE, respectively, and decreased oilseed radish biomass by 65%. There was no decrease in oilseed radish stand density. The results from this study conclude that many of the herbicides commonly used in winter wheat and soybean in Ontario do not negatively impact oilseed radish establishment and growth.
