This study aimed to evaluate the influence of different water depths in the soil on phytoremediation of soil contaminated with picloram by Eleusine coracana plants. The experiment was carried out under greenhouse conditions with samples of Oxisol. The treatments consisted of the combination of four daily levels of water replacement (80, 90, 100 and 110% of evaporated water) and three picloram rates (0, 80 and 160 g ha-1), arranged in a completely randomized design, in a factorial scheme 4 x 3, with four replications. The phytoremediation specie was sowed 48 h after applying the herbicide. At 90 days post emergence, the plants were desiccated and cut and the bioindicator specie (soybean - Monsoy 6101 cultivar) was sowed. The results indicated that the highest evaporated water replacemente depth contributes to the remediation of soil contaminated with picloram, by using Eleusine coracana plants. This phytoremediation improvement only is significant when soil contamination is not over 80 g ha-1.
