I finally was able to visit a Tractor Supply store (new to our area) and was all set to buy some Speedzone (previously the strongest herbicide I could find was Ortho Weed-B-Gone). The price for the Speedzone was $18 for a 20 oz. container. I keep looking around and I find a gallon jug of Trimec 899 for $45. After comparing the labels they seem to be almost identical in active ingredients (and made by the same company too) so I finally figured I might as well take the Trimec 899 as it seemed like a much better deal. I would appreciate thoughts/opinions on these two, are they basically same? And what would be mixing rates for spot spraying - 1oz per 1 gallon of water? BTW - my biggest weed problems are dandelions and clover.
