SELE??O DE PLANTAS QUANTIFICADORAS DE HERBICIDAS RESIDUAIS

摘要

The determination of the concentration of compounds in the soil through plants quantifiers show as the main advantage to detect only biologically active residues, no need for expensive instruments and previous extraction of residues from the soil. Thus, this work aims to select indicator plants the presence of residual herbicides for use in bioassays. The experimental design used was the completely randomized, using the bifactorial arrangement 8x6, with five repetitions. The factor A consisted of the crops and factor B consisted of the preemergence herbicides application. The results show that the sensibility in the detection of herbicide in soil depends on the crop used. The sensibility of species Lactuca sativa L. and Raphanus sativus var. sativus L. don’t permit conditions to quantify the presence of herbicides atrazine, cloransulam, imazaquin, metribuzin and S-metolachlor. Raphanus sativus var. oleiferus Metzger is potencial quantified of imazaquin and S-metolachlor. Plants of Curcubita pepo L. are promising in the bioevaluation of metribuzin. The specie Cucumis sativus L. is potential bioindicator of cloransulan and imazaquin. Avena sativa is potential to quantify imazaquin and metribuzin. Hordeum vulgare L. can quantify metribuzin and Triticum aestivum L. is promising in the detection of atrazine bioavailability
