Resumo: | In an experiment conducted in 1982 at the Centro Nacional de Pesquisa de Trigo-Empresa Brasileira de Pesquisa Agropecuária (National Wheat Research Center of EMBRAPA), Passo Fundo, RS, Brazil, the action of root diseases, rhizophagus insects, and borers Listronotus bonariensis kuschel, 1955 (Col., Curcullonidae), in reducing emergence and in the death of wheat seedlings and tillers, was determined. Tow wheat cultivars, Nobre and CNT 9, under four soil sanitary conditions, were used. Fungicides provided significant increases as to seedling emergence up to 32 days, test weight, one thousand-grain weight, spikes per m2, spikes per plant, grain yield, and reduced infection level of common root rot. Insecticide application resulted in significant increases in number of spikes per m2, spikes per plant, and grain yield, as compared to the control. Low spike rate observed in the experiment may be attributed to soil borne fungi, rizophagus insects, and borers. |

Utilizaram-se as cultivares de trigo Nobre e CNT 9 sob quatro condições sanitárias de solo. O uso de fungicidas proporcionou incrementos significativos quanto à emergência de plântulas até aos 32 dias, peso do hectolitro, peso de mil grãos, espigas por m2, espigas por planta, rendimento de grãos e reduziu o grau de infecção da podridão comum de raiz. A aplicação de inseticidas resultou em aumentos significativos em relação à testemunha, no número de espigas por m2, espigas por planta e no rendimento de grãos. A baixa densidade de espigas, observada no experimento, pode ser atribuída a fungos de solo e a insetos rizófagos e brocas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFerreira Filho, ArmandoReis, Erlei MeloPorto, Miguel D.M.Gassen, Dirceu Neri2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16116Pesquisa Agropecuaria Brasileira; v.19, n.10, out. 1984; 1219-1226Pesquisa Agropecuária Brasileira; v.19, n.10, out. 1984; 1219-12261678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16116/10274info:eu-repo/semantics/openAccess2014-04-16T19:09:29Zoai:ojs.seer.sct.embrapa.br:article/16116Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T19:09:29Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
