Resumo: The lixiviation of herbicides is the most common cause of contamination of subsuperficial water. The objective of this paper was to study the lixiviation of the herbicides imazamox and imazethapyr by means of bioessay. The herbicides were applied to several types of soil into PVC tubes, followed by the addition of 60 mm of water. In each column of soil, leached material was collected and transferred to vases filled with washed sand. Sorghum was sowed in these vases. After seventeen days, the aerial parts and the roots were collected, dried and submitted to a statistic investigation. The lixiviation of imazamox was smaller than that of imazethapyr. As far as types of soil were concerned, there was no difference among them concerning to dry matter weight of the aerial parts. KEY-WORDS: Imazamox; imazethapyr; lixiviation; bioessay.

A contaminação de águas subsuperficiais por agrotóxicos decorre principalmente da lixiviação de seus resíduos. Neste trabalho, estudou-se a lixiviação dos herbicidas imazamox e imazethapyr por meio de bioensaio. Areia lavada e quatro tipos de solo foram colocados em tubos de PVC em posição vertical que, após a aplicação dos herbicidas, receberam lâmina d’água de 60 mm. O delineamento experimental foi o de blocos ao acaso, com quatro repetições e com os tratamentos dispostos no esquema fatorial 2x5. Em cada coluna de solo, coletou-se a solução lixiviada que foi transferida para vasos contendo areia lavada, especificando-se o tratamento recebido. Nos vasos com a solução lixiviada, semeou-se sorgo; aos 17 dias, coletaram-se as partes aérea e do sistema radicular das plantas de sorgo, que foram secadas e analisadas estatisticamente. Nas doses testadas, o imazamox mostrou-se menos lixiviável que o imazethapyr. Ao estudar a lixiviação nos diversos tipos de solo, não se verificou diferença entre eles no que se refere ao peso da matéria seca da parte aérea das plantas, indicando que os solos não influenciaram no comportamento dos herbicidas estudados.
