I have a small amount of horsenettle and a 32oz spray bottle. Wondering how long the Q4 will stay potent once mixed bc I only need a small amount. Will the Q4 kill this weed and not my fescue?
Q4 Plus Turf Herbicide does include deadnettle on the manufacturer's product label, but does not include horsenettle, therefore we cannot confirm it would control it. You could consider a product like EndRun Herbicide, which does include horsenettle and many other broadleaf weeds on the manufacturer's product label, and can be safely applied to fully established fescue lawns if used as directed.
Once diluted, these concentrated herbicides should always be used or discarded within 24 hours of mixing.
