Abstract

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.
