Resumo: | The influence of four planting dates (Oct. 20, 1987; Nov. 17, 1987; Dec. 21, 1987 and Jan. 14, 1988), three seeding rates (32, 54 and 75 seeds/m) and five insecticides (carbofuran 50 G, furathiocarb 666 TS, carbofuran 350 TS, thiodicarb 350 TS e deltamethrin 25 CE) was evaluated on insect damage and grain yield of the upland rice cultivar IAC-47. In overall, the percentage of dead culms caused by Deois flavopicta, Elasmopalpus lignosellus and underground termites ranged from 5.4% to 24.3% and grain production was between 500 and 2,317 kg/ha. Planting in November appeared to be the most efficient procedure to reduce insect damage and attain maximum grain yield. Gain obtained from insecticide applications was greater when rice was planted in October, but it was considerably reduced in November. Association between carbofuran 50 G and the highest seeding rate was very important in reducing D. flavopicta populations for the earliest planting season. |

A porcentagem de colmos mortos por Deois flavopicta, Elasmopalpus lignosellus e cupins rizófilos nos plantios variou de 5,4% a 24,3% e a produção de grãos de 500 a 2.317 kg/ha. O plantio em 17.11.87 foi a principal medida para reduzir o dano das pragas e obter máximo rendimento de grãos (2.317 kg/ha). A vantagem do uso de inseticidas no plantio de 20.10.87 foi muito grande, mas diminuiu consideravelmente no plantio de 17.11.87. Associação do carbofuran 50 G com a maior densidade de semeadura foi muito importante para reduzir as populações de D. flavopicta no primeiro plantio.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFerreira, EvaneCzepak, Cecília1997-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4678Pesquisa Agropecuaria Brasileira; v.32, n.5, maio 1997; 471-480Pesquisa Agropecuária Brasileira; v.32, n.5, maio 1997; 471-4801678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4678/7358info:eu-repo/semantics/openAccess2015-03-17T19:46:25Zoai:ojs.seer.sct.embrapa.br:article/4678Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2015-03-17T19:46:25Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
