“…These symptoms did not affect soybean yield, indicating the selectivity of the combination. ---------%--------- Furthermore, soil and climate conditions interfere with the effects of diclosulam and other pre-emergents on soybean; for example, high rainfall after application can increase soybean injury (8), which may explain what was observed in the present study. According to Pereira et al (2000) and Osipe et al (2014), the application of diclosulam to soybean was selective, alone or in combination with glyphosate, although some symptoms of injury were observed.…”

“…Moreover, there are reports of multiple resistance to glyphosate and chlorimuron (28), to paraquat (1), and to 2,4-D (27), among others. In this sense, an initial application of systemic herbicides, with sequential application of burndown and/or pre-emergent herbicides has proved to be effective and necessary, especially for large plants with a history of herbicide resistance (8,12). Herbicides such as PROTOX or ALS-inhibiting herbicides can be used in sequential applications (12,26,34).…”

The aim of this study was to evaluate the efficacy of sequentially applied herbicides to control Conyza sumatrensis, one of the most widely distributed weeds worldwide, in soybean pre-sowing burndown. The study was conducted under field conditions in the state of Paraná, Brazil, at 2018-2019 growing season. The experiment consisted of a randomized block design with four replicates, with 12 treatments consisting of different herbicide mixtures applied before sowing. Control of C. sumatrensis, injury to soybean plants, and variables related to agronomic performance were evaluated. The control levels were high for all treatments, except for the one that was free of saflufenacil in either of the two applications. These results highlight the importance of saflufenacil in the control of C. sumatrensis and show promise for the use of saflufenacil/imazethapyr when considering the system and other weeds. All studied treatments were selective to soybean, which showed higher injury values in the presence of diclosulam; however, this did not compromise the agronomic performance of soybean. Highlights • Application of systemic herbicides with sequential application of burndown herbicides, is essential for the control of Conyza sumatrensis (>15 cm height).• Saflufenacil, flumioxazin, and imazethapyr stand out in the control of Conyza sumatrensis.• Protox and ALS inhibitors can replace paraquat in sequential application with equal efficacy in the control of Conyza sumatrensis.

“…As previously mentioned, the effect of diclosulam and other pre-emergent herbicides on seed quality is little investigated. Nevertheless, some studies have reported negative effects on soybean with diclosulam or sulfentrazone application, such as injury, stunted plant growth and even yield loss in certain situations (FORNAZZA et al, 2018;DALAZEN et al, 2020;GAZOLA et al, 2021).…”

Can pre- and/or post-emergent herbicide application affect soybean seed quality?

Soybean cultivation requires herbicide application in the off-season, before emergence for weed desiccation, and after emergence. It is believed that the use of preand post-emergent herbicides combined with preharvest application may negatively affect the quality of soybean seeds. As such, the present study aimed to assess the effect of preand post-emergent herbicides on soybean seed quality. Five field experiments were conducted during the 2018/2019 and 2019/2020 growing seasons to investigate the effects of synthetic auxins and pre-emergents, acetyl-CoA carboxylase (ACCase) inhibitors, broadleaf herbicides, and s-metolachlor or clomazone on the quality of soybean seeds. Dicamba application combined with the pre-emergent herbicides imazethapyr/flumioxazin before soybean planting reduced seed vigor and germination. ACCase inhibitors in association with broadleaf herbicides before planting had no effect on seed quality. Applying s-metolachlor (up to 2,880 g of active ingredient [ai] ha-1) or clomazone (up to 1,800 g ai ha-1) was safe for seed germination, even when used after soybean emergence.

“…By controlling the activity of ALS in weeds, it destroys the normal physiological metabolism of weeds and causes weed death [34]. while florasulam [35], penoxsulam [36], pyroxsulam [37], diclosulam [38], and cloransulam [39] are triazopyrimidine sulfonamide herbicides. Triazopyrimidine compounds have become a research hotspot in the discovery of new ALS preparations.…”

Triazole groups play an important role in the construction of agricultural bioactive molecules, often acting as linking units to organically graft different pharmacophore groups, so as to obtain efficient and broad‐spectrum pesticide molecules. After decades of development, triazole derivatives have made remarkable achievements in the discovery of pesticides, especially the discovery of fungicides. In addition, highly effective triazole insecticides, herbicides, and anti‐plant virus agents have also been found, and commercial triazole pesticides have occupied a large market share. At present, the study of triazole compounds has become one of the important fields in the development of new pesticides. We systematically reviewed the application of triazole derivatives in the discovery of new pesticides since 2010, summarized the antifungal, antibacterial, insecticidal, herbicidal, and anti‐plant virus activities of triazole derivatives, and discussed the structure–activity relationship and mechanism of action in order to provide inspiration and ideas for the discovery of new triazole agrochemicals.
