Is using this product in Iowa any concern? Can only find via internet vs. local stores. Grass is mostly bluegrass.
Trimec Southern Broadleaf Herbicide is labeled to treat for corn speedwell. It has about a 14 day soil residual so there shouldn't be any safety concerns. This is a commercial grade product, and would be considered a step above things you can by on a local level.
