Resumo: The use of herbicides has grown progressively. At the same time there has been a great concern about the environment in order to prevent negative environmental impacts. The lixiviation of residues of herbicides is the main cause of the contamination of subsuperficial water. This paper focuses on the lixiviation of the herbicides imazamox and imazethapyr by means of bioessay. Several kinds of soil were placed into PVC tubes in a vertical position. After applying the herbicides, 60 mm of water was put inside the tubes and the leached material of each column was collected. In each column, sorghum was sowed. Afterwards, by means of regression equation, the relationship between dry matter of the aerial part and depth was evaluated. The lixiviation of imazamox was smaller than that of imazethapyr in the different soils. KEY-WORDS: Imazamox; AC 299.263; imazethapyr; lixiviation; bioessay.

O uso de herbicidas nos cultivos agrícolas tem aumentado progressivamente. Concomitantemente, houve também uma crescente preocupação com o meio ambiente, no sentido de prevenir ou mitigar impactos ambientais negativos. A contaminação de águas subsuperficiais por agrotóxicos decorre, principalmente, da lixiviação de seus resíduos. Neste trabalho foi estudada a lixiviação dos herbicidas imazamox e imazethapyr por meio de bioensaio. Diversos tipos de solo foram colocados em tubos de PVC em posição vertical. Após a aplicação dos hermicidas, estes foram atingidos por uma lâmina d’água de 60 mm. Coletou-se o lixiviado de cada coluna, que foi transferido para um vaso correspondente, contendo areia lavada. As colunas de solo foram colocadas em posição horizontal e semeou-se sorgo ao longo da coluna. Posteriormente, relacionou-se, por meio de equações de regressão, a produção de matéria seca da parte aérea em função da profundidade. Nos vasos contendo lixiviado também semeou-se sorgo e, aos 17 dias, colheu-se o material, que foi então analisado estatisticamente. Nas doses testadas, o imazamox mostrou-se menos lixiviável que o imazethapyr, nos diversos solos estudados.
