Established St. Augustinegrass and Centipedegrass: This product may be applied during both dormant and growing seasons.

This product controls Spurweed, Florida Betony, Annual Bluegrass and many other problem weeds in St. Augustinegrass and Centipedegrass turfs. This product will control both emerged weeds and weeds from seeds. 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, rainfallor watering is necessary within 7 to 10 days after treatment.

Spurweed: Control of Spurweed can best be obtained by applying when Spurweed has newly emerged(December and January.)

Florida Betony: This weed emerges in the Fall. Apply this product in mid to late October followed by a second application in mid to late February.

Dichondra, Moneywort: Apply this product in early April followed by a second applicationin July. Note: Applications for Spurweed or Florida Betony generally will give control or suppression of the other listed weeds. However, as a general rule, this product will give best control when applied to young tender weeds or just prior to weed emergence.

    2 of 5 Stars  Trying to kill Pennywort
    By Gary in Oak Ridge, TN on May 30, 2012
    Verified Purchase

    I sprayed the Atrazine as directed and it didnt kill the Pennywort. I waited a week and a half and sprayed some areas again and also some new areas. After another 2 weeks and a couple of rains I noticed some of the Pennywort was dead, but much of the grass around the sprayed areas was dead as well. In general, it killed more grass than Pennywort.

    I mix a bottle of this with Tenacity on my St. Augustine Floratam lawn. The combination works great but it may be all Tenacity. BTW, Tenacity is awesome on Floratam lwans.

    1 of 5 Stars  Atrazine
    By John in Florida on December 29, 2014
    Verified Purchase

    Doesn't seem to be working so well. Thought it worked on st. Augustine grass. weeds are still there and don't seem to be dying

    Expert Response  Expert response:
    It will be tough to use almost any post-emergent herbicide this time of year. Atrazine will provide the best control when weeds are young or just prior to weed emergence. If the weeds are not actively growing, then you will see limited results.

    5 of 5 Stars  Really a weed killer
    By Andres in Gainesville on February 4, 2015
    Verified Purchase

    After fighting with a pest control service for months without results, and my front grass getting worse, I decide to try Atrazine which they said they wouldn't apply. It worked nicely and even in the winter months I cant see any sign of getting back in the weeds. I took my pest control in my own hands and I hope to use many more products as time goes by.

QCan 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.
