Product Information
Hi-Yield Atrazine Weed Killer
Hi-Yield Atrazine Weed Killer is a selective herbicide containing 4.00% atrazine. It is designed for use in established St. Augustinegrass and Centipedegrass lawns to control listed broadleaf and grassy weeds.
This product is a good option for warm-season lawns dealing with weeds such as dollarweed, henbit, chickweed, clover, sandspur, spurge, annual bluegrass, and other listed problem weeds. It works on both emerged weeds and weeds from seed, making it useful for seasonal lawn weed control programs.
Why Choose Hi-Yield Atrazine Weed Killer?
Controls listed weeds in St. Augustinegrass and Centipedegrass
Helps manage both emerged weeds and weeds from seed
Useful for common lawn weeds like dollarweed, henbit, chickweed, and clover
Can be applied during dormant or growing seasons on approved turf
Good fit for warm-season lawn weed control programs
Best Fit for St. Augustine and Centipede Lawns
Hi-Yield Atrazine is made specifically for approved warm-season turf. It is especially helpful when weeds are showing up throughout St. Augustinegrass or Centipedegrass and a selective lawn herbicide is needed instead of a non-selective weed killer.
For best results, apply when weeds are small or actively growing. Treat evenly across the target area and avoid over-applying, especially on stressed turf or areas outside the approved use sites.
How It Works
Atrazine helps control listed weeds through both post-emergent and pre-emergent activity. This means it can help manage weeds that are already visible while also reducing new weed growth from seed in treated areas.
Good Lawn Care Practices
Strong turf helps reduce future weed pressure. Pair herbicide treatments with proper mowing height, watering, fertilization, and lawn maintenance so the grass can fill in thin areas where weeds often take hold.
Important Turf Note
Use Hi-Yield Atrazine only on approved turfgrass. It is not intended for every lawn type, so confirm the grass is established St. Augustinegrass or Centipedegrass before treating.
