| ABSTRACT: The objective of this work was to evaluate the phytoremediation potential of summer-grown species planted in soils contaminated with the herbicides fomesafen or sulfentrazone. In a greenhouse, doses of fomesafen (0.0, 0.125, 0.25 and 0.5 kg ha-1) and or sulfentrazone (0.0, 0.3, 0.6 and 1.2 kg ha-1), were applied in the pre-emergence of brown hemp, millet, velvet bean and sorghum. On the field, the recommended doses of fomesafen (0.250 kg ha-1) and sulfentrazone (0.600 kg ha-1) were used in the pre-emergence of brown hemp, velvet bean and sorghum, plus a treatment without cultivation. These species, before planting canola (bioindicator species), were submitted to mowing and burndown. In greenhouse trials, velvet bean, millet and sorghum tolerated... |
