Brazil's Justice Minister Jose Eduardo Cardozo said Friday that the maraca-like instrument is "not adequate" to be used during the warm-up tournament.
The Brazilian version of the vuvuzela, which had been approved by FIFA, made headlines for the wrong reasons last month after fans upset about their team's loss in a test event threw the green-and-yellow objects onto the pitch.
The announcement of the ban comes just a day after a court order temporarily suspended the Brazil vs. England friendly scheduled Sunday at the new Maracana, saying the venue was not safe for fans. The decision was later reversed after the state government appealed.
