Weeds Controlled or Suppressed:

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.
