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?
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.
