Bob: If it's true that the club has found a good control mechanism for nematodes, that's great news not only for Cypress Point, but for all the courses in San Francisco and on the Monterey Peninsula. They have all been rebuilding greens to battle this problem.
I hope it holds up, but keep in mind that nematodes are a cyclical problem ... a new generation attacks every four months, but the turf can sometimes be quite good in between.
