When used properly, Agralawn Crabgrass Killer causes very little reaction or yellowing to St. Augustine or Bahia lawns. Applying during the a.m. hours while morning dew is present works best or you can wet the affected area with a hose, irrigation or spray bottle. Apply only to the affected area, being careful to dust all of the weeds and/or weed grass you want to control. This product will turn from white to a bright yellow when applied to indicate adequate moisture is present. Apply a light to medium coating in even strokes. Noticeable results should be seen in 3 to 5 days. To avoid washing away product, don't apply if rain is forecasted or directly before watering the lawn. Reapply as needed.
