Resumo: From a commercial granular insecticide applicator for soil application, it was made some adaptations to apply granular insecticides directly into the plant whorl to control the fall armyworm (Spodoptera frugiperda Smith). The machine was adapted in a cultivator so the application of nitrogen on band on the soil surface, the cultivation, and the control of the insect could be done simultaneously. Using the adapted machine, several insecticides were tested on corn and sorghum crops. With the exception of deltamethrin (5.3 grams of active ingredient/ha) and carbofuran (0.44 kg/ha) which were not efficient in controlling the insect, the other insecticides presented a percentage of control varying from 81.2 to 100%. Among them, methomyl, diazinon, forate, chlorpyriphos ethyl, fonofos, quinalphos, carbaryl and acephate were tested. Considering the advantages of granular insecticides (less hazardous to applicator, minimum drift and no water necessity) and the efficiency results obtained, it can be concluded that: the granular applicator, with the described adaptations, can be used to control fall armyworm on com and sorghum with the additional advantage of being used integrated to the operations of nitrogen application and cultivation for weeds.

Esta máquina foi adaptada em um cultivador-adubador, permitindo realizar, simultaneamente, as operações de cultivo mecânico, adubação nitrogenada em cobertura e aplicação de inseticida granulado. Utilizando esta adaptação, foi avaliada uma série de inseticidas na cultura tanto do milho quanto do sorgo. À exceção dos inseticidas deltamethrin (5,3 gramas do princípio ativo/ha) e carbofuran (0,44 kg/ha) que, nas dosagens utilizadas, não deram controle satisfatório do inseto, os demais inseticidas apresentaram uma percentagem de controle variando de 81,2 a 100%. Entre estes, foram testados o methomyl, diazinon, forate, chlorpyrifos ethil, fonofos, quinalfos, carbaril e acephate. Considerando as vantagens apresentadas pelos inseticidas granulados (menor risco de intoxicação, menor probabilidade de provocar desequilíbrio biológico e dispensa de água) e os resultados da eficiência obtidos, pode-se concluir que a granuladeira acrescida das adaptações realizadas pode ser usada para o controle mecanizado da lagarta-do-cartucho em milho e sorgo, com uma vantagem adicional de poder ser integrada às operações de cultivo mecânico e adubação nitrogenada em cobertura.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCruz, IvanSantos, Jamilton P.Waquil, José M.Bahia, Francisco G.T.F.C.2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15304Pesquisa Agropecuaria Brasileira; v.18, n.6, jun. 1983; 575-581Pesquisa Agropecuária Brasileira; v.18, n.6, jun. 1983; 575-5811678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15304/9146info:eu-repo/semantics/openAccess2014-04-16T18:59:25Zoai:ojs.seer.sct.embrapa.br:article/15304Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T18:59:25Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
