If you do not want to disable tracker forever, only temporarily kill all tracker processes, you can use the tracker-daemon utility.
To list all tracker processes:
tracker daemon -p
To kill all tracker processes:
tracker daemon -k
To (re)start all tracker processes (if you want):
tracker daemon -s
More info on tracker-daemon usage:
tracker daemon --help
