Surge Broadleaf Herbicide for Turf, manufactured by PBI Gordon, is a selective, post-emergent herbicide with 4 active ingredients for fast-acting, broad spectrum weed control. Surge can be used to treat annual, biennial, and perennial broadleaf weeds. 

Surge Broadleaf Herbicide is similar to other 3 way herbicides, but also has the addition of sulfentrazone, a powerful herbicide that will inhibit an enzyme (Protox) used for chlorophyll production. This causes plant cell membranes of weeds to rupture. After application, weed injury can be seen within just hours.

Surge Broadleaf Herbicide can be used to selectively kill weeds in both cool-season and warm-season grasses and is rainfast within 6 hours. Surge will help you get rapid and effective results against even the toughest of weeds, such as dandelion, spurge, white clover, and dollarweed.

Tools Needed

To use Surge Broadleaf Herbicide, you will need either a handheld sprayer, a hose end sprayer, a backpack sprayer, or a spray rig for large volume applications.

How to Use

• Step 1: Determine how much Surge Broadleaf Herbicide For Turf you will need by measuring the square footage of the treatment area. Do this by measuring the length and width in feet, and then multiplying them together (length x width = square feet). To find acreage, take your square feet and divide by 43,560. Your mix rate will vary depending on the type of turf you are treating on and the targeted weed type. For acreage application on cool season turf, you will mix between 3.25 to 4 pints of Surge Broadleaf Herbicide for Turf per 10 to 220 gallons of water per acre. For small application rate of cool-seasoned turf, use 1.2 to 1.5 oz. of product per 0.23 to 5.0 gallons of water per 1,000 sq. ft. For acreage application on warm-seasoned turf, apply 2.75 to 3.25 pints of product per 10 to 220 gallons of water per acre. Smaller applications on warm-seasoned turf, use 1.0 to 1.2 oz. of product per 0.23 to 5.0 gallons of water per 1,000 sq. ft. 
• Step 2: To mix, fill your sprayer halfway with water. Add the required amount of Surge Herbicide based on your treatment area. Then fill the sprayer the rest of the way with water, and then shake to ensure an even mix. If adding liquid fertilizer, mix your Surge solution first before adding fertilizer.
• Step 3: Surge can be applied as either a spot application or a broadcast spray. Spray the weed with a fan spray setting, holding the nozzle stationary over the weed to ensure even coverage. Spray weeds to wet, not runoff. Reapplication may be necessary after 30 days for hard to control weeds.
