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.

Hi-Yield Atrazine Weed Killer is safe for St. Augustine and Centipede lawns in GA if applied as directed on the product label for listed weeds.  It 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. Please contact your local cooperative extension office for additional products and recommendations for this application.

Hi-Yield Atrazine Weed Killer will suppress crabgrass, but it may not completely control it with one application, it can take multiple treatments. The best time to treat for post-emergent control is when the weeds are young and actively growing, usually when temperatures are between about 55 and 85 degrees. Please refer to the product label for a complete list of plants controlled and for full application directions. You will want to apply spring and fall pre-emergent herbicide applications to prevent many broadleaf and grassy weeds from germinating. Here is a great article on crabgrass treatment and prevention as well as one for centipede turf care.

Hi-Yield Atrazine Weed Killer is not labeled for basketgrass and unfortunately, basketgrass can be difficult to control. The only herbicide recommended is a non selective glyphosate like Roundup Quick Pro to directly spot treat the basketgrass. In lawn areas, treated areas can be resodded or reseeded after 2 weeks. Other methods of control include hand pulling or hand digging the weed and roots. For landscape beds it is suggested to apply 2-3 inch layer of organic mulch over the area and consider planting with a more desirable ground cover such as Asiatic Jasmine or Liriope which overtime can outlive basketgrass. . .

Hi-Yield Atrazine Weed Killer cannot safely be applied to Fescue lawns. Because poa annua and Fescue are so closely related, there are few products that will kill the poa annua without also harming the Fescue. Your options would be to either spot-treat with a Roundup-type product and then reseed with the Fescue in those areas, or you can use a pre-emergent like Prodiamine 65 WDG in the fall to prevent the poa from growing in the first place. Please review our Poa Annua (Annual Bluegrass) Treatment Guide for more information.
