Hi-Yield Atrazine Lawn Weed Killer is for use to kill weeds and weed seeds in Centipede and St Augustine lawns. This product is a concentrate that is diluted with water and applied using various types of sprayers.

How It Works
Atrazine acts as both a post- and pre-emergent weed control, killing both existing weeds and weed seeds in your lawn. This product may be applied during both dormant and growing seasons.  

Extra Tips
  • Do not apply more than two treatments per year
  • Best results are usually obtained when applied in early Spring or dormant periods when weeds are small or have not emerged
  • Rain or water from irrigation within 2 or 3 days of application may decrease the effectiveness on emerged weeds. However, for the control of weeds from seeds, rainfall or watering is necessary within 7 to 10 days after treatment.
