ENTIRE LAWN TREATMENTS:
This product is intended for use by homeowners on residential lawns including:
- 1. Calculate the total lawn area to be treated. This is done by multiplying the length of the area by the width to obtain total square feet. Prepare only enough spray solution to treat the area calculated.
- 2. Prepare the spray mixture according to the chart below. Carefully measure the proper amount of product to treat 500 sq ft. If more or less than 500 sq ft is to be treated, adjust the amount of product accordingly.
- 3. Shake the spray solution before and during application. Use a spray pattern that gives small droplets without any fine mist.

USE TIPS:
- • Some hard-to-kill weeds may require re-treatment. Wait at least two weeks between applications — some weeds can take that long to die.
- • Spray during growing season when weeds are actively growing.
- • For best results, mow lawn two to three days before treating weeds.
- • To avoid risk of lawn injury, do not spray drought-stressed lawns.
- • Watering immediately after treatment may wash away effectiveness.
- • Wait until newly seeded grass is well established or after the third mowing before applying this product.
- • Treated areas may be reseeded three to four weeks after application.
- • Adjust nozzle to produce a coarse spray. Coarse sprays are less likely to drift. Avoid fine mists.
- • Application to zoysia lawns when they are emerging from dormancy in the spring may cause damage.
- • Overapplication, especially at 90°F or higher, may cause damage.
- • Application to Bermudagrass may cause temporary yellowing when applied at 90°F or higher, but full recovery can be expected.
