Pre-emergent herbicides are not recommended to be used in a hose end sprayer because those sprayers are not accurate enough to apply the correct amount of SpeedZone Southern Herbicide. You will need to use a hand pump sprayer and uniformly spray the product over the specified area. To decide how much water you want to use, you should mark a 1,000 sq ft area, fill your sprayer with water ONLY, and start walking and spraying just as if you were doing the actual application of herbicide. When you are done walking and spraying the 1,000 sq ft area note how much water it took you to spray that area, and that is the amount you will want to mix of product with for each 1,000 sq ft area that needs to be treated. You will need to make sure treated areas are irrigated with at least 1/2 inch of water (either by rainfall or by sprinkler) following the application.
