  • Asked by Bart from Fernandina Beach

    Q
    Can I use Hi-Yield Atrazine Weed Killer to kill bermuda grass in my St Augustine lawn?
    A

    Hi-Yield Atrazine Weed Killer is not labeled to control Bermuda grass in St. Augustine. Unfortunately, because Bermuda and St. Augustine grasses are so closely related, there is nothing that will kill the Bermuda without harming the St. Augustine as well.  It is typically recommended to spot treat the Bermuda with a non-selective glyhposate product and kill it directly, and then replant St. Augustine in those areas if necessary.

    Q
    Will Hi-Yield Atrazine Weed Killer kill Chamber bitter in St. Augustine grass?
    A

    Hi-Yield Atrazine Weed Killer is not specifically labeled for chamberbitter. This is a very stubborn weed. Pre emergent applications with a product like Isoxaben 75 WG have proven to be the most effective way to control this weed. Research from several extension pages do suggest the use of Atrazine for this weed, but we are not able to guarantee its effectiveness. Also keep in mind given how persistent and pesky chamberbitter is, there is no one and done solution to take care of the weed so repeat application may have to take place in order to fully kill the invaders.

  • Asked by Jerry from Davenport Fl

    Q
    Directions say to apply Hi-Yield Atrazine Weed Killer when temp is under 90. What about after application?
    Is it safe to apply if temp goes above 90 say 4 hours after application?
    A

    Hi-Yield Atrazine Weed Killer can be applied early in the morning before temperatures reach 90 degrees if it's expected to get this hot on the day of application.  You just do not want to apply during the time of high temperature because your desirable turfgrass is under more stress in high heat.

  • Asked by John from Mobile, Al
    07/10/2018
    Q
    I have centipede grass but also have rattlesnake weed (Florida Betony) and nothing I've tried kills the weed
    I've tried roundup and another product that I can't remember now what it is but neither of them really worked well. I also have the weed in my flower beds.
    A

    Hi-Yield Atrazine Weed Killer can be used for Florida Betony in centipede lawns.  There is also a great article here by UGA that can help with timing and control methods.  RoundUp is still the best in landscaped/flower beds.
