Thanks guys. I've never used bed pre before. I've always gone with good mulch layer and spot spray with gly at the mowing visit.
Our growing season is March-October. The ext office has used snapshot in the past and they must like it. They are requesting 3 apps a year, so I'm assuming that they are getting decent control over a 4 month period. I'm also guessing I need to bid it at the max rate of 4.6 lbs per 1000 and say that in my bid.
