Application Tips

  • Avoid spray drift and avoid desirable plants.
  • Do not apply when temperatures are above 90 degrees F
  • Apply Southern Ag Atrazine only on healthy turfgrass.
  • Overdosing will cause damage, so do not overlap or use hose-end sprayers.
  • See label for compete instructions and restrictions

Established St. Augustine and Centipede Grass

For best results, apply Southern Ag Atrtazine in early spring or dormant times when weeds are small or haven' t emerged. Irrigation or rain within a couple of days may decrease the effectiveness of Atrazine. However rain or irrigation within 7 days  is necessary for control of weeds from seeds.

Spurweed : Apply in December /January for newly emerged Spurweed for best results.

Florida Betony: Use Atrazine on this weed in the fall (mid to late Oct); follow up with second application in Feb (mid-late Febuary).

Dichondra, Moneywort: Best time to apply this product is in early April and a follow up second application in July.
