Resumo: The chemical control of weeds stands out as an important tool for obtaining high yields in cassava crops. This study aimed at evaluating the selectivity and efficiency of pre-emergent herbicides on cassava (‘Cascuda’ cultivar) crop. The experimental design was randomized blocks, with ten treatments and four replications. The treatments consisted of clomazone (900 g ha-1 and 1,080 g ha-1), flumioxazin (60 g ha-1), sulfentrazone (600 g ha-1), S-metolachlor (1,920 g ha-1), clomazone + flumioxazin (900 + 50 g ha-1), clomazone + sulfentrazone (900 + 500 g ha-1) and clomazone + S-metolachlor (900 + 1,440 g ha-1), as well as a weeded and a non-weeded control. The weed community was composed by 9 families and 12 species, with the Asteraceae and Poaceae families presenting the highest number of species. The pre-emergent herbicides were selective for ‘Cascuda’ cultivar cassava plants. The herbicides were effective in controlling weeds, with flumioxazin (60 g ha-1), sulfentrazone (600 g ha-1), S-metolachlor (1,920 g ha-1) and the mixtures of clomazone + flumioxazin (900 + 50 g ha-1), clomazone + sulfentrazone (900 + 500 g ha-1) and clomazone + S-metolachlor (900 + 1,440 g ha-1) presenting the highest residual effect.

Este estudo objetivou avaliar a seletividade e eficiência de herbicidas, aplicados em pré-emergência, na cultura da mandioca cv. ‘Cascuda’. O delineamento experimental utilizado foi o de blocos ao acaso, com dez tratamentos e quatro repetições. Os tratamentos utilizados foram: clomazone (900 g ha-1 e 1.080 g ha-1), flumioxazin (60 g ha-1), sulfentrazone (600 g ha-1), S-metolachlor (1.920 g ha-1), clomazone + flumioxazin (900 + 50 g ha-1), clomazone + sulfentrazone (900 + 500 g ha-1) e clomazone + S-metolachlor (900 + 1.440 g ha-1), além de uma testemunha sem capina e outra capinada. A comunidade de plantas daninhas foi composta por 9 famílias e 12 espécies, destacando-se as famílias Asteraceae e Poaceae, com o maior número de espécies. Os herbicidas apresentaram-se seletivos às plantas de mandioca cv. ‘Cascuda’, quando aplicados em pré-emergência. Os herbicidas foram eficientes no controle das plantas daninhas, sendo que o flumioxazin (60 g ha-1), sulfentrazone (600 g ha-1), S-metolachlor (1.920 g ha-1) e as misturas clomazone + flumioxazin (900 + 50 g ha-1), clomazone + sulfentrazone (900 + 500 g ha-1) e clomazone + S-metolachlor (900 + 1.440 g ha-1) apresentaram maior efeito residual.Escola de Agronomia - Universidade Federal de Goiás2013-10-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Experimentalapplication/pdfhttps://revistas.ufg.br/pat/article/view/22892Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 43, n. 3, Jul./Sep. 2013; 300-307Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 43, n. 3, jul./set. 2013; 300-307Pesquisa Agropecuária Tropical; v. 43, n. 3, jul./set. 2013; 300-3071983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/22892/15305Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessScariot, Cesar AugustoCosta, Neumárcio Vilanova daBosquese, Everton PauloAndrade, Devair Carlos deSontag, Daniel Adriano2020-07-10T12:41:38Zoai:ojs.revistas.ufg.br:article/22892Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:00.371214Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
