Avoid specific messages like TTY=unknown from logging in /var/log/messages

I am receiving the messages in /var/log/messages and this is populating my /var partition with more space:

“Jun 6 04:02:58 sdp-A sudo: apache : TTY=unknown ; PWD=/var/Tapps/appworks/public ; USER=root ; COMMAND=/bin/rpm -q Tuser”

I want to stop this message from piling up my /var/log/messages , I know logrotate but I am looking for a solution other than logrotate to stop this.
