Bermuda eradication

     The past 3 years we have treated our fairways and tees to stop the spread of Bermuda grass.  We have Bermuda grass all over the golf course.  Our fairways and tees were sodded in Zoysia grass back in the mid 90's.  Bermuda has encroached into the fairways and tees.  In some places it has out competed the Zoysia.  I am using a combination of  herbicides to knock back the Bermuda.  This is a slow process.  We need to treat fairways 3 times one month apart.  The Bermuda will turn brown but will begin to grow out of the effects of the herbicides in about 3-4 weeks that is why we need multiple apps per year.  We can see up to an 80% reduction in a year.  While your playing you will see some brown grass in areas.  That is the Bermuda grass.  Below are a few pictures
