I stopped at a local garden store. I looked at the new Scotts starter fertilizer with weed and crabgrass control, (contains mesotrione). Cost was $69.95 for only 5000 sqft bag--now on sale for only $49.95. Good stuff, I am sure. The woman garden store clerk did not know much about it. Didn't know it was only available from Scotts. Thought it was about the same as the off-brand stuff that only contains prodiamine--these bags claim weed control because they block the seed of a few types of weeds. Exaggerated claim in my opinion.
