In terms of granular products what is your pre-emergent of choice? This is based on overall performance and quality. I know that tupersan is the method of choice if you are also seeding however I've read that it is short-lived. I've heard good things about both dimension and barricade and that they both lasted 3-6 months. The other methods products I haven't heard much about. Comments? BTW, I pulled this list from a google search on pre-emergents so if it looks familiar to you it's because I found it on the internet somewhere.
