Efficacy of selected herbicides in the desiccation of three plant species for soil cover
DOI: 10.7824/rbh.v1i1.316
An experiment was carried out with the objective of evaluating the efficiency of selected herbicides in the desiccation of three plant species in Dourados (MS), Brazil, in 1995/96. A randomized block design was used in three plant species: black oat (Avena strigosa ), millet (Pennisetum typhoydes) and Brachiaria plantaginea, with four herbicides in three rates: paraquat (0.30, 0.40 and 0.60 kg/ha), glyphosate (0.72, 1.08 and 1,44 kg/ha), sulfosate (0.96, 1.44 and 1.92 kg/ha) and glyphosate+2,4-D (0.54+0.67, 0.54+1.0 and 0.54+1.34 kg/ha). The herbicides glyphosate, sulfosate and the mixture glyphosate+2,4-D were efficient to desiccate the three species in all doses. The plants of millet and Brachiaria plantaginea showed a re-growth after 36 days of the application of paraquat.
