Will SedgeHammer Plus Herbicide kill woodsorrel in St. Augustine?

Answer:

Sedgehammer + Herbicide is only labeled to control Purple Nutsedge, Yellow Nutsedge, and Kyllinga and would not control woodsorrel. For woodsorrel in St. Augustine lawns, Hi-Yield Atrazine Weed Killer or Fertilome Weed Free Zone would be a better option.  Please note, Fertilome Weed Free Zone is not recommend to be used on Floratam or Bitterblue varieties of St Augustine unless discoloration and temporary injury can be tolerated. Other species of St Augustine would be safe if used at labeled rates.  View our Woodsorrel (Oxalis) Guide for more information.  Applying a pre emergent such as Pendulum 2G in early Spring and late Fall is recommended to prevent weeds from germinating. This will help cut back on the amount of post emergent applications during the actively growing season. View our Warm Season Lawn Care Schedule for more information.
