Resumo: | The availability of herbicides registered for upland rice is still limited, increasing the management difficulty level for weeds under this crop system. The objective of this study was to evaluate the effect of the ALS inhibitors herbicides application, at different periods, on upland rice (cv. Cambará). The experimental design was randomized blocks with four replications, in a 5x3 factorial scheme, consisting of the herbicide treatments penoxsulam (36 g ha-1), bispiribaque-sodium (50 g ha-1), pirazossulfurom-ethyl (20 g ha-1), 2,4-D (670 g ha-1), and a control, and three application periods: 15, 30, and 45 days after emergence (DAE). Plant phytotoxicity, height, and dry biomass were evaluated at 7, 14, and 28 days after application (DAA), and also the number of panicles m-2, number of grains panicle-1, and yield. It was observed plant phytotoxicity and height decreasing only when applying bispiribaque-sodium, at 15 and 30 DAE. The plant dry biomass was not affected by herbicide application. The number of grains panicle-1 decreased only for pirazossulfurom-ethyl, at 45 DAE. Yield decreased with the pirazossulfurom-ethyl and penoxsulam application, at 45 DAE. Generally the best herbicide application period was 30 DAE. |

Plant phytotoxicity, height, and dry biomass were evaluated at 7, 14, and 28 days after application (DAA), and also the number of panicles m-2, number of grains panicle-1, and yield. It was observed plant phytotoxicity and height decreasing only when applying bispiribaque-sodium, at 15 and 30 DAE. The plant dry biomass was not affected by herbicide application. The number of grains panicle-1 decreased only for pirazossulfurom-ethyl, at 45 DAE. Yield decreased with the pirazossulfurom-ethyl and penoxsulam application, at 45 DAE. Generally the best herbicide application period was 30 DAE. A disponibilidade de herbicidas registrados para o arroz de terras altas ainda é limitada, elevando o grau de dificuldade do manejo de plantas daninhas, neste sistema de cultivo. Objetivou-se, com este trabalho, verificar o efeito da aplicação de herbicidas inibidores de ALS, em diferentes épocas, na cultura do arroz de terras altas (cv. Cambará). O delineamento experimental foi o de blocos ao acaso, com quatro repetições, em esquema fatorial 5x3, constituído pelos tratamentos herbicidas penoxsulam (36 g ha-1), bispiribaque-sódico (50 g ha-1), pirazossulfurom-etílico (20 g ha-1), 2,4-D (670 g ha-1) e uma testemunha, e três épocas de aplicação: 15, 30 e 45 dias após a emergência (DAE). Foram avaliadas a fitointoxicação, altura e fitomassa seca das plantas, aos 7, 14 e 28 dias após a aplicação (DAA), número de panículas m-2, número de grãos panícula-1 e produtividade. Observou-se fitotoxicidade à cultura e redução na altura das plantas apenas com a aplicação de bispiribaque-sódico, aos 15 e 30 DAE. A fitomassa seca das plantas não foi influenciada pela aplicação dos herbicidas. Houve redução no número de grãos panícula-1 apenas para pirazossulfurom-etílico, aos 45 DAE. A produtividade foi reduzida com a aplicação de penoxsulam e pirazossulfurom-etílico, aos 45 DAE. De maneira geral, a melhor época de aplicação dos herbicidas foi 30 DAE.Escola de Agronomia - Universidade Federal de Goiás2011-09-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufg.br/pat/article/view/11584Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 41, n. 3, Jul./Sep. 2011; 408-414Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 41, n. 3, jul./set. 2011; 408-414Pesquisa Agropecuária Tropical; v. 41, n. 3, jul./set. 2011; 408-4141983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/11584/9649Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessPetter, Fabiano AndréZuffo, Alan MárioPacheco, Leandro Pereira2020-07-09T19:17:27Zoai:ojs.revistas.ufg.br:article/11584Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:50.302929Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
