You can use Eraser foaming Weed Killer or Eraser 41% to spot treat for Johnsongrass in your Bermuda lawn. Be careful to apply on days that are not windy because Eraser is a non-selective herbicide that will kill any plants that it contacts. We would also recommend using a pre-emergent herbicide in the Spring to prevent germination of this weed. Pre-emergent herbicides containing the active ingredient Pendimethalin, such as Prodiamine 65 WDG would be a good choice.
