  • KILLS 470+ TYPES OF WEEDS: Broadleaf and grassy weeds such as dandelion, chickweed, clover and yellow nutsedge are targeted (see label for full list).
  • RAINPROOF: Rainfall or watering 3 hours after application will not wash away effectiveness.
  • COVERAGE: 32-ounce bottle treats up to 5,000 square feet, helping you treat larger patches with one product.

How to use effectively

  • Apply when temperatures are between 45 and 90 degrees Fahrenheit for best results.
  • Spray until wet to ensure contact with visible weeds while avoiding excess runoff.
  • Do not apply when daytime temperatures exceed 90 degrees to reduce the risk of lawn injury.
  • Read the label fully before use to follow directions and safety guidelines.

Imagine a lawn where crabgrass and similar invaders are managed with a single, ready-to-apply concentrate. You may notice weed activity respond within hours, and you can plan applications around typical lawn care routines. The product is designed to be user-friendly for homeowners who want a practical option for weed control, while still considering the needs of a healthy lawn.
