“…Furthermore, herbicides can reduce the first pod's height, especially when it triggers high injury levels. For example, fomesafen and cloransulam-methyl were applied on Roundup Ready® soybean at a labeled rate reduced 22% the HFPI (Novakoski et al 2020).…”

“…Other studies evaluated lactofen (an herbicide with the same mode of action as fomesafen) with the aim of reducing growth, with some promising results being observed, with doses close to those recommended for weed control (Novakoski et al, 2020;Martins et al, 2020). Or even the postemergence application of fomesafen (393 g ai ha -1 ), which caused injury to soybean plants, with reduced growth, but ¹ g ae ha -1 for glyphosate and 2,4-D.

The objective was to evaluate the production components of soybean and the physiological quality of seeds according to the application of subdoses of herbicides at the reproductive stage of healthy plants. The treatments consisted of the application of glyphosate (122.5 g acid equivalent [ae] ha -1 ), chlorimuron (1.75 g active ingredient [ai] ha -1 ), 2,4-D (134 g ae ha -1 ), fomesafen (60 g ai ha -1 ), glufosinate (55 g ai ha -1 ), paraquat (35 g ai ha -1 ), and control (no application). The chlorophyll index, agronomic performance, and physiological quality of seeds were evaluated. Glyphosate, chlorimuron, fomesafen, or glufosinate resulted in an increase in soybean plant height. Chlorimuron increased yield compared to the control. Paraquat or glufosinate, despite the injury, did not reduce yield, but the application of these herbicides is not recommended to stimulate plant development, given the potential for injury. The 2,4-D was the only one that caused a reduction in the physiological quality of soybean seeds.

“…Therefore, different concentrations of herbicides may affect aquatic organisms, especially glyphosate (Rzymski et al 2016). From the results of this work, it is possible to perform a screening of which herbicides could be explored in future studies, investigating different dosages, plant lodging levels (Novakoski et al 2020), and which herbicides could be omitted. For example, taking Fig.…”

Heteranthera reniformis (mud plantain) is a weed of aquatic habit, which currently causes losses in the production of ornamental plants and irrigated crops, such as rice, and for which there are no herbicides registered in Brazil with proven control effectiveness. This study evaluated the control effectiveness of individual and multi-mixture herbicides (i.e., glyphosate, 2,4-D, triclopyr, paraquat, oxyfluorfen, sulfentrazone, carfentrazone, diuron and S-metolachor) on post-emergence of mud plantain. An organosilicone spreader adjuvant was also evaluated. Weed injury assessments were carried out over time, at 7, 14, 21, 42, and 60 days after application (DAA) of the herbicides. At the end of the study (60 DAA), the weed dry matter was measured. The progress of weed injury was modeled using a time-trend decomposition procedure based on the LOcally wEighted Scatterplot Smoothing (LOESS) method. Treatments with glyphosate application proved to be more effective in relation to mud plantain injury over time, with a slight emphasis on treatments associated with triclopyr. However, evaluating the dry matter, the treatment with glyphosate alone was more effective; besides, it showed short-range injury variance in the control of H. reniformis. The inclusion of organosilicone adjuvant to some treatments was not quite successful. Regardless of the herbicide used, higher levels of initial injury are a fair predictor of final control effectiveness (i.e., period after the herbicide effect). On the other hand, less initial injury corresponded directly to low control effectiveness. The results suggest that the herbicides, glyphosate, triclopyr, and carfentrazone, are suitable for mud-plantain control.
