|Foreign Couch sprayed out.|
At this stage we have only treated patches in the middle of the greens as treating the encroaching Couch on the edges would require the greens to be closed to play as above. This was mentioned at the Course Information session earlier this year when I advised that the greens would need to be closed, as to achieve a result with the weedkiller you would require at least 3 applications, and the chance of this chemical being "tracked" on to the green is a danger. The 3 applications need to be 7 - 10 days apart to achieve a result and the greens would then need to have the entire perimeter sod cut out and the turf replaced and such a process is impossible whilst play continues. We tried to perform this operation on greens 11,16 and 17 on the River course in 2007 with only 1 spray and leaving the greens in play. Almost all the foreign Couch returned to these areas within 12 months.
