Is SedgeHammer Plus Herbicide safe for switchgrass to kill yellow nutsedge? Switchgrass is used for wildlife cover.


SedgeHammer Plus Herbicide is not labeled safe or tolerant on switchgrass. Unfortunately, the best option for treating nutsedge in switchgrass would be use a non selective herbicide such as glyphosate and spot treat the weeds directly. You can harvest the switchgrass high enough to leave actively growing weeds, then apply glyphosate at 1 to 2 quarts per acre..It is important to wait until the switchgrass is dormant so that it is not damaged by the glyphosate. Check with your Extension agent or other experts for information on which herbicides are labeled for use in the state and county where you will be using them.
