Tools Needed
You will need either a handheld sprayer, backpack sprayer, or a hose end sprayer. For most general applications, a handheld or backpack sprayer is recommended.
This product will need to be applied with an oil concentrate such as a nonionic surfactant.
How to Use
- Step 1: Determine how much Ferti-lome Over the Top ll Grass Killer to use by measuring the treatment area square footage. To find the square footage, measure it in feet and then multiply the length and width together (length X width = square footage). For spot treatments and hose end sprayer applications, apply 1 fl. oz. of Ferti-lome Over the Top ll Grass Killer with 1 fl. oz. of oil concentrate per gallon of water per 1,800 sq. ft. For example, if you have a treatment area of 5,400 sq. ft., divide this by the standard treatment area square footage (1,800) to determine you will need 3 fl. oz. of product and surfactant to apply for the total treatment area (treatment area / 1,800 sq. ft. = 3 oz. of product and surfactant to use).
- Step 2: To mix, you will first fill your selected sprayer halfway with the appropriate amount of water, then add the measured amount of Ferti-lome Over the Top ll Grass Killer and surfactant, and add the remaining amount of water inside the sprayer. Secure the sprayer lid, then shake thoroughly until the spray mixture is evenly mixed.
- Step 3: Go to the application area and pump the handle of the sprayer to pressurize. For hose-end sprayers, adjust the sprayer settings until the sprayer can be applied at a low-pressure volume. With your selected sprayer, apply a coarse spray pattern evenly to the targeted area and weed surfaces until wet. Avoid spraying to the point of runoff. Depending on the location and foliage, a second application can be applied, but the time it can be applied will vary.
