That is Poa annua. It is hard to control in the grasses that you have listed in the fact that all of those are cool season grasses. Most herbicides are going to kill the grass as well as that weed. We use to say in turf school that one year of seed equalled seven years of weeds. It is tough to control. Alot of golf courses fought to keep it out of the greens and just ended up converting the greens to it instead of trying to kill it. Get in touch with your local golf course superintendent to find out your options in your area. I am sure he/she has and does deal with it.
