I have had a few comments about the foreign grasses that are appearing in the West course greens which I did mention a couple of posts ago. It is a perennial problem at this time of year when the Bent greens are at their weakest after a long hard summer and the invading grasses are at their healthiest and therefore more prominent. This is particularly the case with the encroaching Couchgrass which is at its worst at this time. Its a bit like "groundhog day" as this problem is raised at this time every year and a quick perusal of old Course Committee minutes demonstrates this. I actually have a copy of minutes from 1980 (March 1980 by coincidence) that mention the encroachment of Couchgrass and even contains a recommendation to convert all greens to 328!! In years gone by the method used at CTHGC was to fumigate and either re-turf or re-sow the entire green and this would require a temporary green to be in play for anywhere up to 16 weeks. Fumigation is not available now so either a total kill spraying program or re-construction would need to take place, meaning even a longer period of interruption to play. I have adopted a containment strategy on the West greens as there is no one product that can selectively remove Couchgrass, in particular, from Bent greens without causing damage. As mentioned a couple of posts ago the Bent greens are under enough stress and the addition of weed control products would only put more pressure on them. A lot of encroachment information was covered in posts last year and you can quite easily refer back to them for more information.
