Pre-emergent crab grass inhibitor/Episode ATH-523
I just sent this request to ATOH and thought I might also get a response in this forum.
Question:'Ask This Old House' Episode ATH-523
I was just watching an episode of 'Ask This Old House' (airtime 21-Sep-2009 7:30-8:00 pm DIY Channel Episode ATH-523).
Roger Cook described a product but I only heard its name which sounded like Tupacent <sp?>. Apparently this product can be used in the spring to inhibit crabgrass but it doesn't affect grass seed germination? I can't seem to find anymore info on it. Can you confirm the spelling of this product and/or provide more information?
Great show BTW!
Thanks in advance,
