Abstract Background The corn intercropping with Brachiaria ruziziensis has rapidly raised in South and Center-West of Brazil. However, the uncertainty about forage interference on corn yield has led growers to use herbicides to suppress ruzigrass. Objective Our objective was to evaluate sub-doses herbicides applied in different stages of ruzigrass to suppress the growth in an intercropping system with corn. Methods A greenhouse experiment was carried out to evaluate the forage intoxication by herbicides to select the best treatments. Subsequently, a […]
