Resumo: The persistence of linuron in the soil was investigated under field conditions in three types of soil during the years 1983/84, 1984/85 and 1985/86 on soybeans (Glycine max Merrill). Soil samples were taken periodically from the field experiments to determine herbicide activity. The bioassay methodology conducted under controlled conditions of a phytotron was utilized. The results indicated that linuron bioactivity, in doses equivalent to 1.75 kg/ha persists in the soil, at a depth of 0 cm to 10 cm, three weeks after its application in pre-emergence. For periods superior to four weeks, bioactivity disappeared. Lower doses of the product tend to persist for shorter periods.

Dos experimentos de campo foram retiradas, periodicamente, amostras de solo para determinação da atividade do herbicida. Empregou-se a metodologia de bioensaios conduzidos em condições controladas fornecidas por um fitotron. Os resultados demonstraram que, em doses de 1,75 kg/ha, o linuron permanece com bioatividade no solo, à profundidade de 0 cm a 10 cm, três semanas após a sua aplicação em pré-emergência. Para um período superior a quatro semanas, o solo não apresentou mais persistência do produto. Doses mais baixas do produto tendem a apresentar períodos menores de persistência. Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBlanco, Hélio GarciaOliveira, Domingos de AzevedoMatallo, Marcus Barifouse2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/13763Pesquisa Agropecuaria Brasileira; v.23, n.1, jan. 1988; 19-25Pesquisa Agropecuária Brasileira; v.23, n.1, jan. 1988; 19-251678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/13763/7808info:eu-repo/semantics/openAccess2014-09-05T14:20:18Zoai:ojs.seer.sct.embrapa.br:article/13763Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-09-05T14:20:18Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
