Resumo: | The effect of trifluralin on weeds and its influence on bean production was studied in field trials at the Experimental Station of Ponta Grossa, Paraná, in 1968 and 1969. Several levels of trifluralin were tested, as well as the effects of EPTC and a mixture of trifluralin plus EPTC. A control, cultivated plots, and a trifluralin level combined to one cultivation were also considered for further comparison. Treflan (45% of trifluralin) and Eptam-6E (77% of EPTC) were the available herbicides chosen. The main weeds which occurred in the experimental areas were Brachiaria plantaginea (L.) Hitch., Digitaria sanguinalis (L.) Scop. and Raphanus raphanistrum, L. The results show that trifluralin gave good control effect on grasses but not on broadleaves. Better results were obtained under higher soil humidity conditions. Doses of 0,90, 0,75 and 0,68 l/ha of trifluralin showed good weed control, improving bean yield. Under low soil humidity conditions, higher doses were more efficient. At levels higher than 1,35 l/ha, trifluralin caused stand damage. The application of 0,37 l/ha of trifluralin was the most favorable treatment on an economic basis, when one cultivation was performed during the whole cycle of the culture. Levels of 0,75 and 0,56 l/ha were less efficient than normal cultivation. Eptam-6E, at the dose of 3,08 l/ha, was not an efficient weed control. |

A trifluralina foi testada em diversas doses e seu efeito foi comparado a tratamentos com capinas e sem capinas. Comparou-se também o efeito da trifluralina com o efeito do EPTC, com mistura de trifluralina mais EPTC, e com associação de trifluralina e uma capina. Nestes experimentos foram usados os herbicidas Treflan e Eptam-6E. O Treflan possui cerca de 45% de trifluralina e o Eptam-6E possui cerca de 77% de EPTC. As principais invasoras encontradas na área dos experimentos foram o papuã, Brachiaria plantaginea (Link.) Hitch., o pé-de-galinha, Digitaria sanguinalis (L.) Scop., e o nabo forrageiro, Raphanus raphanistrum, L. Pelas informações obtidas foi constatado que a trifluralina apresentou bons resultados sobre gramíneas, ao passo que sobre invasoras de folha larga foi ineficiente. O efeito deste herbícida sobre as invasoras foi maior com teores mais elevados de umidade do solo. Doses de trifluralina de 0,90, 0,75 e 0,56 l/ha apresentaram bons resultados sobre as invasoras gramíneas, com influència positiva sobre a produção do feijão; quando o solo apresentava baixo teor de umidade, as doses mais altas foram mais eficientes no controle das invasoras. Doses superiores a 1,35 l/ha acarretaram diminuição da população de plantas de feijão. No aspecto econômico, apresentou vantagem a aplicação de 0,37 l/ha de trifluralina, em associação com uma capina durante o ciclo da cultura; doses de 0,75 e 0,56 Ilha foram inferiores à prática de capinas. O herbicida EPTC, na dose em que foi usado, não controlou as invasoras presentes nas parcelas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBuss, Afonso2014-04-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/17531Pesquisa Agropecuaria Brasileira; v.8, n.8, 1973: Série Agronomia; 203-207Pesquisa Agropecuária Brasileira; v.8, n.8, 1973: Série Agronomia; 203-2071678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/17531/11754info:eu-repo/semantics/openAccess2014-04-15T18:50:52Zoai:ojs.seer.sct.embrapa.br:article/17531Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-15T18:50:52Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
