The preemergent they use, Tupersan (siduron), won't affect turfgrass germination. Scott's has some pretty questionable recommendations when it comes to fertilizing, but even they wouldn't sell a product for use on seeds that prevented them from germinating.

Hi, tiemco. Thats what I thought too. But it seems too good to be true. Well, I'll give it a shot.

Where in CT are you from? I'm in North Glastonbury.

I'm down on the coast, Fairfield. I've used Tupersan, it works, but it only prevents about 6-7 weeds (crabgrass being the most significant), is expensive, and doesn't last very long (about a month). You can probably get away with using it for two months, then by that time you will probably be able to use a post emergent herbicides if necessary, but only if the label says you can. Good luck.
