David from Phoenix, Arizona writes
To provide some background, I live in Phoenix, Arizona and have crushed granite gravel as a ground cover in both front and back yards. I have a 1-gallon battery operated sprayer. I performed a test with water to determine the area the 1-gallon sprayer will dispense. I was only able to cover a 10 x 22 area or 220 square feet before the water ran out. With that said, how much Dimension product should I use per 1-gallon? If my calculations are correct, I should be using .08 to .1 ounce of product. Also, what, if any, is the harm if I used more than the recommended amount?
In Arizona, you would generally make two applications of Dimension 2EW Herbicide 5 to 10 weeks apart. We would recommend the Program 2 or 3 rates of 1 oz per 1,000 sq ft and then 1.5 oz per 1,000 sq ft, or 2 applications of 1 oz per 1,000 sq ft each, according to the product label. Be sure that you immediately water-in the application with a high volume of water any time there is a barrier like gravel over the ground. This will help get more of the active ingredient down to the soil so that it is not just absorbed into the rocks before it can reach the dirt. (Since this product is still intended to be used around turfgrass and ornamentals, you may not get the same results on a stone area.) At the 1 oz,1000 sq ft rate, you would use 0.22 oz of Dimension 2EW in 1 gallon in your sprayer to cover 220 sq ft.
