“…These results of previous studies (Correia et al, 2008;Lopes-Ovejero et al, 2013), and that of the present study, highlight the importance of sequential applications and/or mixtures of herbicides in Benghal dayflower control. In particular, Protox-inhibiting herbicides or glufosinate was effective in controlling Benghal dayflower (Ferreira et al, 2017;Santos Junior et al, 2019). In the present study, sequential application of glufosinate + saflufenacil after the first application of herbicides was effective and a predominant factor in controlling this weed.…”

É notória a eficácia de glufosinate + saflufenacil no controle de plantas daninhas, mas qual o incremento da eficácia de controle da primeira aplicação de herbicidas devido à aplicação sequencial, ou ainda quais seriam as melhores misturas de herbicidas na primeira aplicação com a aplicação sequencial de glufosinate + saflufenacil? Objetivou-se avaliar a eficácia de herbicidas, seguidos ou não da aplicação sequencial de glufosinate + saflufenacil, no controle de Conyza spp. (buva) e Commelina benghalensis (trapoeraba) no período de entressafra, anteriormente à semeadura da soja. O experimento foi conduzido em 2020, em Palotina, Paraná (PR), utilizado delineamento em blocos casualizados, com quatro repetições. Os tratamentos foram dispostos em arranjo fatorial (19 x 2), utilizados 19 níveis para a primeira aplicação, compostos pela aplicação isolada ou em misturas de glyphosate, glufosinate, carfentrazone, saflufenacil, dicamba e 2,4-D. O segundo fator foi representado pela aplicação, ou não, em sequencial de glufosinate + saflufenacil. A aplicação sequencial incrementou a eficácia de todos os tratamentos no controle de trapoeraba, independentemente dos herbicidas utilizados na primeira aplicação. A aplicação de glufosinate + saflufenacil foi eficaz no controle da buva, seja na primeira ou na aplicação sequencial. A aplicação única em manejo de entressafra, antecedendo a soja, não é a indicação mais viável. Destaca-se a importância das misturas de saflufenacil com carfentrazone no controle de trapoeraba, e com dicamba, no controle de buva.

“…Entretanto, em vários estudos os efeitos sinérgicos e aditivos entre o glifosato (inibidor da EPSPS) com o carfentrazone e saflufenacil (inibidores da PROTOX) em diferentes combinações foram comprovada tanto para o controle de monocotiledôneas perenes como Commelina spp. e Digitaria insularis (Ferreira et al, 2017;Presoto et al, 2020), quanto no controle de eudicotiledôneas anuais como Conyza spp., e Ipomoea hederifolia (Dalazen et al, 2015;Agostineto et al, 2016;Silva et al, 2018). Portanto, o uso da mistura glifosato + carfentrazone no controle da monocotiledônea perene M. sobolifera pode também garantir o controle de outras espécies presentes nas áreas agrícolas independentemente da classe ou ciclo biológico, considerando que as doses de controle desta espécie foram similares às demais opções encontradas na literatura.…”

Paraquat: mode of action and historical aspectsParaquat and diquat are bipyridylium herbicides with photosystem I electron diversion mode of action. They have contact action, limited translocation and rapid Abstract: Background: Paraquat is a broad spectrum herbicide used particularly in burndown, in pre-plant of row crops and in the pre-harvest desiccation of some crops. In Brazil, paraquat was re-evaluated by Anvisa, leading to a prohibition of production and sales on September 22, 2020, and used until July 31, 2021. Objective: The objective of this review is to characterize the use of paraquat in Brazil and describe the status in other countries, particularly the agronomic implications of its ban, possible replacements, and scenarios. Review: The use of paraquat is important for weed management in different production systems. Owing to its toxicity, its use has been reevaluated in several countries. For pre-harvest desiccation of soybeans, diquat, glufosinate, and some combinations with Protox inhibitors are highlighted as alternatives to paraquat. For pre-harvest desiccation of common beans, diquat, saflufenacil, and glufosinate could be used; however, only glufosinate could be used for wheat. For managing broadleaves weeds, glufosinate, saflufenacil, carfentrazone, and diquat are effective alternatives. Diquat may be less effective in controlling Conyza spp. resistant to paraquat. For grasses control, glufosinate, in addition to ACCase inhibitors and possible mixtures, may be helpful. Although pre-emergent herbicides are not classified as desiccant herbicides, they contribute to weed management. The adoption of herbicide-tolerant crops, mechanical control, and cover crops can be added as agricultural practices for integrated weed management. Conclusions: Due to the ban on paraquat, challenges arise, and the most often suggested replacements are glufosinate, diquat, and Protox inhibitors; however, grass control will be of greater concern.
