    Q
    Can I use Southern Ag Atrazine Weed Killer to kill weeds growing on desert landscape?
    I have weeds growing on my rocks because I live in Southern Nevada. I want to know if this product will kill all weeds or just the specific kind that grows on St Augustine Grass?
    A

    Southern Ag Atrazine Weed Killer for St. Augustine Grass is only for use in St. Augustine and Centipede grass lawns and not in any landscaped areas.  Surlan is our most popular pre-emergent product for rock landscapes to help prevent weeds from growing.  Depending on the type of weeds you are trying to control in the landscaped area Hi-Yield 2, 4-D Selective Weed Killer would be good for existing broadleaf weeds. Fertilome Over the Top II Weed Killer would be good for grassy weeds.

  • Asked by Ricky from Salado, Tx
    03/16/2021
    Q
    Can I use Atrazine and Barricade a day apart on St. Augustine prior to rain/watering?
    A

    We recommend that you use them one week apart to avoid over-stressing your turf. You should apply the Barricade first as it needs to be watered in. Atrazine is a bit different. Rain or water 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.

    Q
    Can Southern Ag Atrazine Weed Killer for St Augustine Grass be safely used on St. Augustine, Bermuda and Zoysia lawns?
    What pre emergent can be used on all 3 turfgrasses to prevent weeds from germinating?
    A

    Southern Ag Atrazine Weed Killer for St Augustine Grass would only be safe for St. Augustine and Centipede lawns, not for use on Zoysia or Bermuda lawns. 

    Blindside Herbicide WDG would be a selective post emergent labeled for over 70 broadleaf and grassy weeds that is safe for St. Augustine, Zoysia and Bermuda turgrasses. 

    For selective pre emergent herbicides, either Dimension 2EW or Pendulum 2G would provide broad spectrum pre emergent control of listed weeds on the product label.

    View our Pre Emergent Guide for addtional information on selecting a pre emergent. 

    For exact timing recommendations, we suggest contacting your County cooperative extension office for information on estimated timing to apply pre emergents for best results. Post Emergents should be applied anytime the weeds are actively growing when air temperatures are between 65-85 degrees. 

    Please view our Lawn Care Guide for treatment guides based on some of the most common weeds and product recommendations.
