“…Among the pre-emergent herbicides, an effect was observed for the imazethapyr/flumioxazin premix. Marchi et al (2021) worse performance in relation to the control (no herbicide), chlorimuron and sulfentrazone. However, flumioxazin did not influence germination, vigor or other parameters for this cultivar and none of the parameters for TMG7062 IPRO.…”

“…For pre-emergent herbicides, studies have evaluated their effectiveness in weed control (DE SANCTIS et al, 2021;PATEL et al, 2023) and/or selectivity for soybean, as well as their effect on initial growth, yield and other agronomic performance parameters (FORNAZZA et al, 2018;ARSENIJEVIC et al, 2021). Research on the quality of the seeds produced is scarce; however, Marchi et al (2021) found that flumioxazin applied preemergence had a minimal effect on the electrical conductivity of soybean seeds.…”

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.

“…Se han desarrollado varios estudios que abordan el tema del uso de herbicidas como desecantes para diversos cultivos, como soja (Glycine max) (Marchi et al, 2021), frijol común (Phaseolus vulgaris) (Lima et al, 2018), sorgo (Sorghum bicolor) (Barros et al, 2019) y trigo (Triticum) (Souza et al, 2020). Sin embargo, para el cultivo de frijol existen pocos trabajos que puedan orientar a los agricultores en la elección del desecante adecuado, especialmente en la región norte de Brasil.…”

“…En términos generales los valores de emergencia fueron aceptables, con medias superiores al 95 % (Cuadro 4). Según los resultados obtenidos por Marchi et al (2021), el flumioxazin causó reducciones en el vigor de la semilla de soya, pero no afectó significativamente la germinación, ni la calidad general de las semillas. Por su parte, Raisse et al (2020) obtuvieron semillas con germinación superior al 80 % en plantas desecadas con flumioxazin y diquat.…”

“…Glufosinate may or may not have negative effects on seed quality, depending on the application timing and dose (Pereira et al, 2015a;Botelho et al, 2019;Zuffo et al, 2020). Many stressors, such as herbicides that cause changes in soybean physiology, can affect the seed quality (Albrecht et al, 2012;Marchi et al, 2021).…”

Glufosinate and diquat may have different levels of efficacy in the pre-harvest desiccation of soybean (Glycine max (L.) Merr.) plants, and may affect quality of seeds differently, depending on the phenological stage at which they are applied. The objective of this study was to evaluate desiccation with glufosinate and diquat at the phenological stages R6, R7.1, R7.2, and R7.3, and to examine their effects on yield and quality of soybean seeds. The experiment was conducted at two sites in the state of Paraná (PR), Brazil, in the 2020-2021 crop season. A randomized block design was used, treatment groups consisted of application of glufosinate or diquat at R6, R7.1, R7.2, and R7.3, and the control group (without desiccant application). Defoliation, maturity, moisture, yield, and seed quality (vigor and germination) were evaluated. Glufosinate and diquat were effective at desiccation and had a significant effect on defoliation and maturity, with final values ≥ 98.8% and ≥ 99.3% respectively. Treatments can accelerate harvest maturity by approximately 3 d and earlier applications do not necessarily favor this acceleration, most notably in trial 1. However, desiccation at earlier stages reduced seed yield and negatively affected seed quality, with values of only 61.3% and 71.8% of vigor and germination in some situations. The application of glufosinate or diquat was effective in the pre-harvest desiccation of soybean plants, with no differences between the assessed herbicides or phenological stages. The application of glufosinate starting at R7.2 or diquat at R7.3 is ideal to avoid deleterious effects on seed yield. Applications at earlier stages may lead to losses of more than 30% seed yield. The use of diquat or glufosinate before R7.2 may reduce the quality of seeds.
