Pumas fans are being urged to stay silent when the All Blacks take their kicks on Sunday.
The two teams will do battle in Argentina this weekend.
Rugby Without Borders spokesman Alejandro Sangenis says before the game, the captain of the Pumas will ask supporters not to whistle or boo.
"Rugby fans need to go back to their old values, Argentines were called the 'white knights' of rugby, and we would like to go back to that, to the real spirit of rugby.''
Alejandro Sangenis says there was a lot of whistling when the Pumas played the Springboks in Mendoza.
