No annual ryegrass, but this year had quite a bit of pythium in Tucson. I would imagine there was a fair amount in your area as well. I have never used barenburg, or annual ryegrass, but 600 may not have been high enough of a rate this year with the extended summer we had and the rain letting the bermuda to overtake pretty much anything it wanted.
It would be hard to say for sure if it was the seed or not, but I will say I have used seed that was well below what I'd consider acceptable, we made a switch two years ago from that source to a new one and wouldn't go back unless we had to.
