What can I use to kill buffalograss in a St. Augustine lawn?

Answer:

With Buffalograss being very tolerant to herbicides and St. Augustine/Centipede type lawns are very sensitive to herbicides, we recommend spot treating with a Glyphosate product such as Roundup QuikPRO. Spot treating will allow you focus your application directly to the targeted weeds and not damaging your grass. Roundup QuickPRO is a non-selective systemic herbicide and will only kill the weeds that are sprayed. It does not stay in the soil so any weeds that are beneath soil, will not be affected. Multiple applications may be needed. For further assistance on what the best herbicides are for treating buffalograss in your region, contact your local Master Gardener at the link below.  Master Gardener - http://npic.orst.edu/mgamlr.html
