    I am licensed and was wondering if you guys have found anything than works well at killing Johnson Grass (Sorghum halepense) without causing harm to established turf fescue lawns?

    If my memory serves me right Johnson grass is an annual, like crabgrass. Dimension pre emerge might help. You might have to experiment with rates and split applications. Mowing at 3-4 inches would help thicken the fescue to crowd it out. Fertilizing heavy when the fescue is growing, spring and fall.
