Resumo: The degradation of aldicarb in samples collected from the different horizons of four representative soils in Lavras, MG, Brazil, was investigated under laboratory conditions. Subsamples of each soil were incubated with the chemical during periods varying from 1 to 80 days. Aldicarb and its oxidation products, aldicarb sulphoxide and sulphone, were extracted with acetone and determined, as aldicarb sulphone, by liquidgas chromatography, with a flame photometric detector. The breakdown of aldicarb to noncarbamate products closely followed a firstorder kinetics with halflife values of 66, 155, and 236 days, respectively for A, B and C horizons of the Dark-Red Podozolic; 65, 137 and 281 days for the horizons A, B and BC of the Red-Yellow Latosol; 146 and 183 days for the horizons A and B of the Dusky-Red Latosol and, 113 and 108 days for the horizons A and C of the Low Humic Gley soil.

Subamostras dos solos foram incubadas com o composto durante períodos que variaram de 1 a 80 dias. Os resíduos de aldicarbe e de seus produtos de oxidação (sulfóxido e sulfona de aldicarbe) foram quantificados conjuntamente, na forma de sulfona de aldicarbe, por cromatografia gás líquido. Os valores de meia-vida de degradação para os solos estudados foram: 65, 137 e 281 dias, respectivamente, para os horizontes A, B e BC do solo LVA; 66, 155 e 236 dias, para os horizontes A, B e C do solo PVE; 146 e 183 dias, para os horizontes A e B do solo LR e, 113 e 108 dias para os horizontes A e C do solo GPH.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBarbosa, Tânia Maria LealRigitano, Renê Luís de Oliveira1994-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4137Pesquisa Agropecuaria Brasileira; v.29, n.6, jun. 1994; 955-960Pesquisa Agropecuária Brasileira; v.29, n.6, jun. 1994; 955-9601678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4137/1428info:eu-repo/semantics/openAccess2012-02-13T20:45:05Zoai:ojs.seer.sct.embrapa.br:article/4137Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-02-13T20:45:05Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
