Resumo: | The soil persistence of ametryne, atrazine, simazine and diuron (2.8 kg/ha of each product), was investigated. They were applied in the month of September, during three years, under field conditions of day soil sugar-cane crop at Limeira, SP, Brazil. Analyses of soil samples, collected at 0 cm to 10cm and 10 cm to 30 cm depth, 30, 60, 90, 120, 150 and 160 days after the herbicide applications showed through oat bioassays in phytotron conditions that at 0 cm to 10 cm of depth the soil did not present residual bioactivity of ametryne, 90 days after its application; for atrazine, simazine and diuron, this phenomenon happened after 60 days. Soil samples of 10 cm to 30 cm of depth did not show presence of herbicides. |

Amostras de solo, coletadas à profundidade de 0 cm a 10 cm e 10 cm a 30 cm, em épocas correspondentes a 30, 60, 90, 120, 150 e 180 dias após a aplicação dos produtos, foram submetidas a bioensaios conduzidos em um fitotron para determinação da persistência dos produtos. Os resultados demonstraram que para as condições climáticas de primavera, ametryne não mais apresenta bioatividade residual no solo para plantas sensíveis, na camada de 0 cm a 10 cm, 90 dias após a sua aplicação; no que se refere aos herbicidas atrazine, simazine, e diuron essa situação foi alcançada já aos 60 dias. Nenhum herbicida provocou efeitos cumulativos no solo no período estudado, nem foi percolado para a camada de 10 cm a 30 cm de profundidade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBlanco, Hélio GarciaOliveira, Domingos de Azevedo2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/16318Pesquisa Agropecuaria Brasileira; v.24, n.9, set. 1989; 1161-1168Pesquisa Agropecuária Brasileira; v.24, n.9, set. 1989; 1161-11681678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/16318/10529info:eu-repo/semantics/openAccess2014-08-28T20:08:00Zoai:ojs.seer.sct.embrapa.br:article/16318Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-28T20:08Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
