Resumo
The objective of this study was to evaluate the herbicide bentazon for weed control in a consortium containing corn, palisadegrass (Brachiaria brizantha cv. Marandu), and Macrotyloma axillare cv. Java, and eucalyptus, in an agrosilvopastoral system. Experimental design was completely randomized with four replicates, and treatments were arranged in split plots. The plots were crop arrangements and
subplots were the bentazon doses (0, 0.36 and 0.72 kg a.i. ha-1). Crop arrangements containing eucalyptus, corn, and palisadegrass showed the lowest dry mass of weeds, while corn monoculture, without herbicide application, showed highest incidence of weeds. All crop arrangements contained dicot weeds, but monocot weeds were only observed in treatments that contained java, and in corn monoculture. All plots treated with bentazon showed high corn grains yields, and corn monoculture produced the highest. Based on the results of this study, the application of bentazon and the use of palisadegrass may decrease weed pressure. Aiming corn yield in agrosilvopastoral
system, weed control can be with 0.36 kg a.i. ha-1 of bentazon.
