Resumo: The objective of this work was to evaluate the degradability of paclobutrazol in soil. Soil samples were collected in orchards of two main mango production regions for exportation, at Petrolina, PE and Lins, SP, Brazil. Blended bacteria cultures, isolated from the soil samples, were assessed in liquid culture medium enriched with paclobutrazol, to verify its degradative capability. Quantification of growth regulator residues by high performance liquid chromatography was performed 15 days after application of the compound, and showed that the paclobutrazol is slowly degraded and presents half-life of 95 days.

Os solos foram coletados em regiões representativas de plantios comerciais de manga para exportação, em Petrolina, PE e em Lins, SP. Culturas bacterianas mistas, isoladas destas amostras de solo foram avaliadas quanto à sua capacidade degradativa em meio de cultura líquido suplementado com paclobutrazol. A determinação dos resíduos do regulador de crescimento, realizada a partir do 15o dia de incubação e quantificada por meio de cromatografia líquida de alta eficiência demonstrou que o paclobutrazol é lentamente degradado e apresenta meia-vida de 95 dias.–Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSilva, Célia Maria Maganhotto de SouzaFay, Elisabeth FrancisconiVieira, Rosana Faria2003-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6693Pesquisa Agropecuaria Brasileira; v.38, n.10, out. 2003; 1223-1227Pesquisa Agropecuária Brasileira; v.38, n.10, out. 2003; 1223-12271678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6693/3750info:eu-repo/semantics/openAccess2010-08-19T19:03:30Zoai:ojs.seer.sct.embrapa.br:article/6693Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-19T19:03:30Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
