What's Up With #2 Bleaching Her Hair?

You may notice some grass that looks almost white on number two. This is part of a trial I am conducting to gauge the effectiveness of a specific herbicide on killing goose grass. Following the warm winter our goose grass population seems to be worse than normal. I am looking for an efficient and cost-effective way to control it. If found to be effective, I intend to apply this product while we are closed for aerification. By the time the golf course recovers, the grass should also be green where we apply this product.
