Resumo: Nicosulfuron is the commonly used herbicide for the control of annual weeds and broadleaf weed species in maize production. However, little is known about the length of time nicosulfuron can remain in the spray tank prior to application in the field without impacting efficacy. The objective of this study was to evaluate the effect of different storage times of the nicosulfuron spray solution on phytotoxicity, production and physiology of Marandu palisadegrass [Urochloa brizantha (Hochst. ex A. Rich.) R. D. Webster cv. Marandu]. The experiment was analyzed in a 6 × 5 factorial arrangement with a complete randomized design. The treatments were six storage times of the nicosulfuron spray solution (0, 6, 12, 24, 48 and 72 h) applied in the Marandu palisadegrass, and five evaluation periods (0, 7, 14, 21 and 60 days after application). Phytotoxicity by the nicosulfuron in the Marandu palisadegrass had parabolic pattern as a function of the interaction between storage time and evaluation period. The photosynthetic rate decreased as a function of the days after nicosulfuron application and showed a discrete increase as a function of the spray solution storage time. Nicosulfuron solution acidifies with time and the effects on phytotoxicity decreased by 30% after 72 h.

Sin embargo, no se sabe mucho respecto al tiempo que el nicosulfuron puede permanecer en el tanque de pulverización antes de la aplicación en el campo sin afectar la eficacia. El objetivo de este estudio fue evaluar el efecto de los diferentes tiempos de almacenamiento de la solución de pulverización de nicosulfuron sobre la fitotoxicidad, la producción y la fisiología de la hierba Marandu [Urochloa brizantha (Hochst. Ex A. Rich.) R. D. Webster cv. Marandu]. El experimento se analizó en una disposición factorial de 6 × 5 con un diseño aleatorio completo. Los tratamientos fueron seis tiempos de almacenamiento de la solución de pulverización de nicosulfuron (0, 6, 12, 24, 48 y 72 h) aplicada en la hierba Marandu, y cinco períodos de evaluación (0, 7, 14, 21 y 60 días después de la aplicación). La fitotoxicidad por el nicosulfuron en la hierba Marandu tuvo un patrón parabólico en función de la interacción entre el tiempo de almacenamiento y el período de evaluación. La tasa fotosintética disminuyó en función de los días posteriores a la aplicación de nicosulfuron y mostró un aumento discreto en función del tiempo de almacenamiento de la solución de pulverización. La solución de nicosulfuron se acidifica con el tiempo y los efectos sobre la fitotoxicidad disminuyeron en un 30% después de 72 h.O nicosulfuron é o herbicida comumente utilizado para o controle de plantas daninhas anuais e espécies de folhas largas na produção de milho. No entanto, pouco se sabe sobre o período de tempo em que o nicosulfuron pode permanecer no tanque de pulverização antes da aplicação no campo sem afetar a eficácia. O objetivo deste estudo foi avaliar o efeito de diferentes tempos de armazenamento da solução de pulverização do nicosulfuron na fitotoxicidade, produção e fisiologia do capim-marandu [Urochloa brizantha (Hochst. Ex A. Rich.) R. D. Webster cv. Marandu]. O experimento foi analisado em esquema fatorial 6 × 5, com delineamento inteiramente casualizado. Os tratamentos foram seis tempos de armazenamento da solução de pulverização de nicosulfuron (0, 6, 12, 24, 48 e 72 h) aplicada no capim-marandu e cinco períodos de avaliação (0, 7, 14, 21 e 60 dias após a aplicação). A fitotoxicidade pelo nicosulfuron no capim-marandu teve padrão parabólico em função da interação entre o tempo de armazenamento e o período de avaliação. A taxa fotossintética diminuiu em função dos dias após a aplicação do nicosulfuron e teve um discreto aumento em função do tempo de armazenamento da solução de pulverização. A solução de nicosulfuron acidifica com o tempo e os efeitos na fitotoxicidade diminuem em 30% após 72 h.Research, Society and Development2020-06-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/471310.33448/rsd-v9i7.4713Research, Society and Development; Vol. 9 No. 7; e778974713Research, Society and Development; Vol. 9 Núm. 7; e778974713Research, Society and Development; v. 9 n. 7; e7789747132525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/4713/4192Copyright (c) 2020 Leandro Diego Silvainfo:eu-repo/semantics/openAccessSilveira, Raul RibeiroSantos, Márcia VitóriaSantos, José Barbosa dosFerreira, Evander AlvesSilva, Leandro Diego da2020-08-20T18:05:03Zoai:ojs.pkp.sfu.ca:article/4713Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:28:28.410458Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
