Control of Conyza spp. with sequential application of glufosinate in soybean pre-sowing

Abstract: Conyza spp. is among the main weeds reported worldwide. Due to its aggressiveness, such as high seed production and dispersion, and the growing reports of biotypes resistant to glyphosate, paraquat, and other herbicides, different control practices are required. Thus, this study aimed to evaluate the efficacy of herbicides with sequential application of glufosinate in soybean pre-sowing for control of Conyza spp. with indicative of resistant to paraquat. The study was carried out in the field, at Assis Chateau… Show more

“…Em vez disso, baixas taxas de translocação resultam de a ausência de um transportador ativo eficiente. Albrecht et al (2020) aplicaram o tratamento glyphosate + 2,4-D (1500 + 670 g i.a. ha -1 ), com sequencial de amônio glufosinato (400 g i.a.…”

“…A proibição do uso do paraquat apenas reforça a necessidade da caracterização e delineamento de novos manejos. Neste sentido, pode ser ressaltado o glufosinate (Tahmasebi et al, 2018;Albrecht et al, 2020c;Cantu et al, 2021;Albrecht et al, 2021), o que foi observado neste estudo, principalmente, por exemplo, nas associações com saflufenacil. A aplicação de glufosinate + saflufenacil também é destacada em outros trabalhos como eficaz no controle da buva (Waggoner et al, 2011;Zobiole et al, 2018).…”

“…The ban on paraquat reinforces the need for the characterization and configuration of new management. Therefore, glufosinate has been highlighted (Eubank et al, 2008;Frene et al, 2018;Tahmasebi et al, 2018;Albrecht et al, 2020c;Cantu et al, 2021). Saflufenacil can also be used as an alternative for the control of Conyza spp.…”

“…In addition, pre-emergent protoxinhibiting herbicides, such as flumioxazin and sulfentrazone (Zimmer et al, 2018). Furthermore, some commercial premixes are already available to the producer or soon available, such as sulfentrazone/diuron, imazethapyr/ flumioxazin, saflufenacil/imazethapyr, among others (Albrecht et al, 2020c). Moreover, non-chemical measures, such as cover crops and straw formation, should be highlighted for the management of Conyza spp.…”
