Resumo: | Three field experiments were conducted including several insecticides with different formulations, dosages and application methods to control the lesser cornstalk borer (Elasmopalpus lignosellus) on maize (Zea mays L.). In relation to the application methods, insecticides were applied in furrow at planting time as seed coating and as spray after plant emergence. Evaluations were based on the number of emerged plants (initial stand), number of surviving plants (final stand), number of attacked plants, and yield. The number of attacked plants was surveyed in alternated days. Insecticides applied as planting time gave good protection of the seed and/or seedlings against soil pests. Aldrin in seed coating and endrin in furrow were among the best insecticides in relation to the number of emerged plants. However, they did not have any effect on the lesser cornstalk borer. For this insect the best insecticides were thiodicarb (035, 1 and 2.25 liters of active ingredient per 100kg of seeds), carbofuran in seed coating and granular application and methomyl in granular application. Plots treated with thiodicarb and carbofuran yielded 60% more than the untreated ones. The insecticides in spray application were not efficient in controlling the pest on maize. |

Foram utilizados produtos aplicados no solo ao plantio, misturados à semente de milho (Zea mays L.) para plantio imediato, e na parte aérea, com jatos dirigidos para o colo da mesma no início do ataque. As avaliações foram baseadas no número de plantas emergidas, de plantas atacadas, de plantas sobreviventes e na produção. As plantas atacadas foram contadas em dias alternados, e eliminadas. Os produtos aplicados no plantio proporcionaram boa proteção às sementes e/ou plantas recém-germinadas, do ataque de pragas do solo. Aldrin misturado à semente e endrin pó seco aplicado no sulco ofereceram bom efeito quanto ao número de plantas emergidas, mas nenhum efeito no controle da lagarta-elasmo. Para tal, os melhores inseticidas foram thiodicarb (0,75, 1 e 2,25 litros do i.a./100 kg de sementes), carbofuran granulado e liquido misturado à semente, e methomyl granulado. Parcelas tratadas com thiodicarb e carbofuran produziram em média, 60% a mais do que as testemunhas. Os inseticidas foliares aplicados no inicio do ataque, nas dosagens utilizadas, não foram eficientes no controle da lagarta-elasmo, em milho.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCruz, IvanOliveira, Lenita J.Santos, Jamilton P.2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15480Pesquisa Agropecuaria Brasileira; v.18, n.12, dez. 1983; 1293-1301Pesquisa Agropecuária Brasileira; v.18, n.12, dez. 1983; 1293-13011678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15480/9426info:eu-repo/semantics/openAccess2014-04-16T18:50:15Zoai:ojs.seer.sct.embrapa.br:article/15480Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:50:15Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
