It is now easy to see the areas treated with weed killer on the River greens where the surrounding "green" couch has encroached into the putting surface.
The photo below shows the progress of spraying the “green” couch out of the 328 greens. It is easy to see that the 328 has melted out very quickly and the “green” couch is still quite strong. This is the reason that you need at least 3 app
lications of weed killer to hopefully get a full kill and even after 3 sprays this is not always guaranteed. At this stage there has only been some minor tracking of the weed killer away from the treated area with the 10th River green the worst, even though it only had 2 relatively small patches sprayed!
