Established St. Augustinegrass and Centipedegrass:
This may be applied during both dormant and growing seasons. Best results are usually obtained when applied in early Spring or dormant periods when weeds are small or have not emerged. Do not apply more than two treatments per year. This controls Spurweed, Florida Betony, Annual Bluegrass and many other problem weeds in St. Augustinegrass and Centipedegrass turfs. This 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.
WARNING: This product can expose you to chemicals including Atrazine, which is known to the State of California to cause birth defects or other reproductive harm. For more information go to https://www.P65Warnings.ca.gov -

Atrazine

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:
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.
