Resumo: The behaviour of the insecticide carbaryl was studied during eight weeks by means of radiometric techniques in samples of Brunizem and Dark-Red Latosol soils from Paraná, Brazil. Groups of oxidized, sterilized and untreated soils with and without glucose additions were incubated with 14C-carbaryl and analyzed. In both soils, results showed an increase in the degradation rate of carbaryl in oxidized samples whereas adding glucose did not influence its degradation rate. Three metabolites having Rf 0.23, 0.40 and 0.70 were detected.

Grupos de solos autoclavados, oxidados e sem tratamento prévio, com e sem adição de glicose, foram incubados com carbaril-14C e analisados durante oito semanas. Constatou-se que a oxidação proporcionou, em ambos os solos, um incremento acentuado na degradação desse defensivo agrícola, ao passo que a adição de glicose teve pouca influência nos processos degradativos. Foram detectados três metabólitos com Rf 0,23,0,40 e 0,70.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraHirata, RodobikoRüegg, Elza Flores2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15698Pesquisa Agropecuaria Brasileira; v.20, n.6, jun. 1985; 621-629Pesquisa Agropecuária Brasileira; v.20, n.6, jun. 1985; 621-6291678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15698/9708info:eu-repo/semantics/openAccess2014-04-17T11:54:13Zoai:ojs.seer.sct.embrapa.br:article/15698Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-17T11:54:13Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
