Resumo: In order to determine the efficiency of herbicide mixtures against annual weeds and their phytotoxic effects in cotton (Gossypium hirsutum L. r. latifolium Hutch.) a field trial was placed in 1979 at Surubim, State of Pernambuco, Brazil. The results showed that the mixtures test [trifluralin ppi (pre planting incorporated) + diuron pre (pre-emergence); trifluralin ppi + fluometuron pre; pendimenthalin + diuron pre; pendimethalin + fluometuron pre; alachlor + diuron pre; alachlor + fluometuron pre] showed to be selective to cotton plants, effective against annual weeds for a period of approximately 60 days, and none of the herbicide mixtures affected the yield and fiber qualities of cotton. The predominant weed species were: Ageratum conyzoides L, Boerhavia diffusa L., Acanthospermum hispidum DC., Cenchrus echinatus L., Digitaria sanguinalis Willd. and Rhynchelitrum roseum (Ness) Stapf et Hubb.

Os resultados indicaram que as misturas testadas (trifluralin ppi + diuron pré; trifluralin ppi + fluometuron pré; pendimethalin + diuron pré; pendimethalin + fluometuron pré; alachlor + diuron pré e alachlor + fluometuron em pré-emergência) mostraram-se, indistintamente, seletivas às plantas do algodoeiro, apresentaram um eficiente controle de ervas daninhas anuais por um período de 60 dias após a germinação do algodão e não interferiram no rendimento nem na qualidade da fibra do algodão produzido. As ervas daninhas predominantes foram: Ageratum conyzoides L., Boerhavia difusa L., Acanthospermum hispidum DC., Cenchrus echinatus L., Digitaria sanguinalis Willd e Rhynchelitrum roseum (Ness) Stapf et Hubb.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraAzevêdo, Demóstenes Marcos Pedrosa deBeltrão, Napoleão Esberard de MacêdoNóbrega, Laudemiro Baldoíno da2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14866Pesquisa Agropecuaria Brasileira; v.22, n.8, ago. 1987; 797-802Pesquisa Agropecuária Brasileira; v.22, n.8, ago. 1987; 797-8021678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14866/8571info:eu-repo/semantics/openAccess2014-10-08T19:20:43Zoai:ojs.seer.sct.embrapa.br:article/14866Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-08T19:20:43Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
