Paspalum control

The collars at Bernardo Heights CC are sea spray paspalum and have been creeping into the greens at a reasonable pace.  In the last six weeks, we've edged the the collars three times and filled the gap with a little sand.  This process uses a walking edger, the same type a homeowner could use to edge their sidewalks.  In some locations, the paspalum is already 10 inches into the green and well rooted.  We recently applied a herbicide to control this encroachment and the results were very good.  Sometimes when you see something that looks dead, it is, and we did it on purpose.

Abel, our spray tech, applied the herbicide with a paint roller for an exact application.  The bentgrass was unharmed and we found our new control strategy.  The brown areas will fill in with healthy bent grass and we may topdress and seed to move along the recovery process.
