PROCOPIO, S.O. et al. Potential of plant species for remediation of trifloxysulfuron-sodium. Planta daninha [online]. 2005, vol.23, n.1, pp. 9-16. ISSN 0100-8358.  http://dx.doi.org/10.1590/S0100-83582005000100002.

This work aimed to evaluate the efficiency of vegetable species in the remediation of the herbicide trifloxysulfuron-sodium in soils using the common bean (Phaseolus vulgaris) as a bio indicator. The treatments were composed by the combination of the species Calopogonium mucunoides,Crotalaria juncea, Crotalaria spectabilis, Vicia sativa, Cajanus cajan, Canavalia ensiformis, Medicago sativa, Dolichus lab lab, Penisetum glaucum, Stylosantes guianensis, Mucuna deeringiana, Mucuna cinereum, Mucuna aterrima, Raphanus sativus and Lupinus albus, sown in vases the day following application of the herbicide at three doses (0.00; 3.75; and 15.00 g ha-1.) Eighty days after sowing, the plants were cut and the shoot discarded, followed by bean ("Perola" cultivar) sowing. At 45 days post emergence, bean height and shoot dry matter were evaluated. Greater efficiency in trifloxysulfuron-sodium decontamination in soil was obtained with the species M. aterrima and C. ensiformis.
