Step by Step Instructions

How to Use

  • Turn on water and extend hose to farthest area of the measured area to be treated.
  • Spray evenly over the entire measured area. Stop by sliding thumb activation switch backward to OFF position.
  • Turn off the water and then relieve water pressure by sliding thumb switch to ON position until water slows to a drip. Then, slide switch back to OFF position.
  • Disconnect sprayer from hose.

When and Where to Use

Where Not to Use

  • For the safety of our customers and the environment,
  • Do not use this product to control weeds in vegetable gardens, flower beds, around shrubs, or near ornamental plants.

Where to Use

  • The advanced formula is intended for use only on residential lawns including Kentucky bluegrass, perennial ryegrass, fescues, common bermudagrass, hybrid bermudagrass, bahiagrass, bentgrass, buffalograss, centipedegrass, zoysiagrass, and St. Augustinegrass (except Floratam).

When to Apply

  • For the best weed killing results, spray when broadleaf weeds are young and actively growing, and air temperatures are not expected to exceed 90°F for 6 hours.
  • Although this herbicide can be applied in the spring, summer, or fall, summer applications tend to be less effective.
  • Under adequate soil moisture conditions, spring and fall treatments tend to offer best results.

How Often to Apply

  • Despite the power of this herbicide, certain persistent weeds may require a repeat application no sooner than 30 days after initial application.
  • To ensure the longevity of your lawn, limit treatments (including spot treatments) to 2 per year.

Special Instructions

Protect the desirable plants in your yard by avoiding a fine mist spray, as this can drift and raises the risk for injury to surrounding species.

Watering Tips

  • Enhance the effectiveness of this product by applying to lawns with adequate soil moisture and favorable growing conditions.
  • If your lawn is a bit thirsty, schedule a time to water at least 1 day before and after the application to maximize effectiveness.

  • You may apply plant food and soil one week following the herbicide application.
