CONTROL:     BBRLG suggests either cutting and painting or spraying with Brush Off (or equivalent).  Use a more concentrated mix to cut and paint.  To do this, sever the stems close below the leaves close to ground and “paint” the chemical on the severed stem within 15 to 20 seconds.  Follow-up next season too.  You can also use mechanical, hand pulling and don’t forget to re-vegetate once the blackberry is gone.  Hit the plant when it is growing.
