I just finished reading that as well. Thanks for the help. I guess I was looking for "spot spraying" to hit me in the face.The label states 0.75 to 1.5 fluid ounces in 0.5 to 6 gallons of water per 1000 square feet. It goes on to mention spot treatment is defined as a treatment area no greater than 1000 square feet per acre.
If it were me, I would go 1 ounce of product to 2 gallons of water for spot treatment.
Thanks Riggle, yeah if you do that let us know your results.Justwanna,
myself I prefer to add a gallon of water to the sprayer. Spray a concrete driveway wet and measure how much area 1 gallon covers in sqft. Then add herbicide according to the square feet covered per gallon. Write it on the sprayer in marker. I normally cover 2,000 to 3,000 sqft per gallon. (Use the same pressure and walking speed.)
For ease of measurement, then make a reverse fill chart. Suppose 1 ounce herbicide requires a half-gallon, 2 ounces a full gallon and 3 ounces 1.5 gallons. Use the chart; add herbicide; add water to match herbicide. Print fill chart using Excel spreadsheet. Cover with clear tape--but good luck keeping it dry.
Use same idea with a backpack sprayer.
Maybe I can test this plan again tomorrow before it snows. Let everyone know what sqft I get from my sprayers.
