Resumo: | Residues of DOT and endrin in cotton seeds (Gossypium hirsutum L., cultivar IAC-17), oils and meals were determined by gas chromatography in the State of São Paulo, Brazil. Sprayingapplications were made at 76, 56 and 31 days before harvest at the following dosages: 2000 g a.i./ha DDT and 8009 a.i./haendrin, applied as a wettable powder formulation for DDT and as an emulsifiable concentrate for endrin. The persistence of both insecticides in cotton seeds was similar, considering the amount applied and the final residues, which were 0.099 ppm of total DDT residues (sum of p,p'-DDE, o,p'-DDT and p,p'-DDT) and 0.04 ppm of endrin residues. The crude oil has showed higher residue levels: 0.181 ppm and 0.083 ppm for total DDT and endrin, respectively. The meals have showed lower residue levels: 0.025 ppm of total DDT and 0.01 ppm of endrin. The residue levels found in cotton seeds were in accordance with the official tolerances, which are 1.0 ppm for total DDT residues and 0.1 ppm for endrin residues, with a safety interval of 30 days. |

As aplicações foram feitas aos 76, 56 e 31 dias antes da colheita, nas dosagens de 2.000 g i.a. DDT/ha e 800 g i.a. endrin/ha, sendo a formulação do DDT a de pó molhável e a do endrin, concentrado emulsionável. Em caroços, a persistência dos dois inseticidas foi semelhante, considerando a quantidade aplicada e o resíduo final que foi de 0,099 ppm de DDT total (soma de p,p'-DDE, o,p'-DDT e p,p'-DDT) e 0,04 ppm de endrin. O óleo bruto apresentou resíduos mais altos: 0,181 ppm de DDT total e 0,083 ppm de endrin. No farelo, os resíduos foram menores: 0,025 ppm de DDT total e 0,01 ppm de endrin. Os resultados em caroços, respeitado o período de carência de 30 dias, estiveram abaixo dos limites de tolerância (1,0 ppm para DDT total e 0,1 ppm para endrin) estabelecidos pela legislação brasileira.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraNovo, José Poleze SoaresBatista, Gilberto Casadei deLima, Urgel de AlmeidaCia, Edivaldo2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15976Pesquisa Agropecuaria Brasileira; v.17, n.7, jul. 1982; 993-997Pesquisa Agropecuária Brasileira; v.17, n.7, jul. 1982; 993-9971678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAspahttps://seer.sct.embrapa.br/index.php/pab/article/view/15976/10096info:eu-repo/semantics/openAccess2014-04-16T16:21:36Zoai:ojs.seer.sct.embrapa.br:article/15976Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T16:21:36Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
