| Abstract | Sequential application of flumicloracpentil for Euphorbia heterophylla control in soybeans. Wild poinsettia (Euphorbia heterophylla) is one the most important weeds in soybean fields in the state of Parana, not only for its dissemination, but also due to its natural difficulty of controlling features by herbicides and to occurrence of resistant biotypes. Facing those problems, an evaluation of the field and greenhouse trials was carried out in order to check the efficacy of postemergence sequential application of flumiclorac pentil to control this weed. Sequential applications of flumicloracpentil were more efficient than a single application, promoting, at least, 86% of weed control on the 24 th day after the second application of the sequential treatments. All the evaluated combinations of flumiclorac rates once sprayed at two true leaves stage, promoted adequate control of E. heterophylla. Comparing the greenhouse and the field results, it was concluded that, under field conditions, the canopy provided by the crop helps to improve the weed final control. |
