John from Mundelein, Illinois writes

Will Tenacity Herbicide eradicate black medic and quackgrass?

Answer:

No, Tenacity is not labeled to treat black medic or quackgrass per the product label. The common recommendation is to kill the quackgrass with a glyphosate product like Roundup QuikPRO and then reseed after 2 weeks.  For Black Medic, if you have cool season turf then we would recommend Hi-Yield Triclopyr Ester, if you have a warm season grass then we would recommend a product such as Surge Broadleaf Herbicide. Please be sure to review the product labels for your turfgrass and mix rates.
