Tools Needed

You will need a garden hose to attach it too. 

How to Use

  • Step 1: Determine how much Fertilome Weed-Out Lawn Weed Killer RTS to use by measuring the square footage of the treatment area. Find the square footage by measuring the treatment area's length and width in feet, then multiplying them together (length X width = square footage). For the southern (warm season) grasses, apply the entire contents of this container (32 fluid ounces) on 8,000 square feet of turf [4 fl. oz. per 1,000 sq. ft.]. For the northern (cool season) grasses, apply the entire contents of the container (32 fluid ounces) on 6,000 square feet of turf [5.3 fl. oz. per 1,000 sq. ft.].
  • Step 2: Shake well before using. Connect the sprayer to the hose. Turn on the water from the garden hose. 
  • Step 3: To begin spraying, point the nozzle in the direction you want to spray. Bend the small plastic tab back and turn the knob clockwise to ON position. Spray evenly to the area to be treated. Refer to the sight gauge clear view strip (graduated scale) on the side of the container to determine the amount of product sprayed.
  • Step 4: To stop spraying, turn the knob counter-clockwise to OFF position. Turn off the water. Relieve water pressure by [bending the plastic tab back and] turning the knob to ON position until the water slows to a drip. Then turn the knob back to OFF position. Disconnect the sprayer from the hose.

Where to Use

Fertilome Weed-Out Lawn Weed Killer RTS can be used in residential and ornamental lawns. Established turf of northern (cool season) and southern (warm season) grasses may be treated.

The northern (cool-season) turfgrasses include Kentucky bluegrass, perennial ryegrass, and the fescues. 

The southern (warm season) turfgrasses include St. Augustinegrass, centipedegrass, bentgrass, bahiagrass, and bermudagrass.

When to Use

For best results, spraying should be done when broadleaf weeds are young and actively growing. Older weeds will be harder to kill. Spray at any time during the growing season when weeds are actively growing, although the spray works faster with temperatures above 70 degrees Fahrenheit. 

To avoid damage, do not apply to St. Augustinegrass or centipedegrass while emerging from winter dormancy.

Damage may also occur on these grasses if temperatures drop below 45 degrees Fahrenheit within 72 hours of application. 

Avoid spraying St. Augustinegrass when temperatures are above 90 degrees Fahrenheit and under conditions of high humidity

Safety Information

Do not allow people or pets to enter the treated area until the sprays have dried.

Special Considerations

This product may be injurious to St. Augustinegrass, bentgrass and centipedegrass under conditions of high temperature and moisture.
