    Q
    Can I apply Hi-Yield Atrazine Weed Killer on dormant Bermudagrass?
    The UGA extenstion states: "Atrazine is labeled for centipedegrass, zoysiagrass, St. Augustinegrass and bermudagrass. Atrazine can be applied to actively growing and dormant centipedegrass or St. Augustinegrass but bermudagrass can be injured if treated while actively growing. " So, can it be used to control actively growing annual bluegrass on a dormant Bermuda grass lawn?
    A

    Hi-Yield Atrazine Weed Killer is not labeled to be used on bermudagrass at all so we cannot recommend it for this use.  We have to go by what is stated on the product label.  Drive XLR8 would be a good product to use for annual bluegrass in bermuda.

    Can you spray the soil with atrazine before installing new St. Augustine sod?

    We wouldn’t recommend using Hi-Yield Atrazine prior to laying St Augustine sod.  The label states that it should only be applied to turf that isn’t under stress, and mentions that it could stunt the growth of or yellow sprigged turf
