Resumo
In the search for natural herbicides for the management of the Cyperus rotundus L. in crops this work evaluated alternative methods to control weed, aiming at sustainability. The experiment was carried out in pots, in a greenhouse at the Experimental Station Lageado, FCA-UNESP-Botucatu, from april to may 2008. The experimental design was entirely randomized, with three repetitions, and treatments consisted of aqueous extract of Stilozobium aterrimum Piper & Tracy, residue of the green manure on the soil surface and incorporated into soil, homeopathic preparations and control treatment with no applications. The aqueous extract of green manure and homeophathic preparation provided both reduction in the development of C. rotundus. The fresh weight of the aerial part of S. aterrimun stimulated the growth of the weed both as cover and incorporated into the soil.
