two or three applications of mesotrione at 0.28 or 0.42 kg·ha −1 a.i. beginning in early June provided inconsistent levels (13%–92%) of CBG control. The 0.42 kg·ha −1 a.i. rate applied three times, however, provided 92% to 100% CBG control in both

Brazil is high with an average K application rate of 189 kg·ha −1 reported by Bernardi et al. (2002) and 166 kg·ha −1 reported by IBGE (2017) but varies considerably: 199–374 kg K/ha, 64–250 kg N/ha, and 196–371 kg P/ha ( Schepers et al., 2015
