Will Q4 Plus harm Panicum (switchgrass) species?

Wild onions and some other weeds are invading a large bed of Panicum virgatum. If I apply Q4 Plus is there any risk of damage to the switchgrass plants? Thanks!

Answer:

Q4 Plus Turf Herbicide should only be applied to lawns that are established and listed on the label. Avoid applications around plants including switchgrass plants due to possible injury.
