It's mid-September southern Oklahoma and would like to apply the second application in midland Bermuda to control Johnson grass.
For best results on seedling Johnsongrass, apply Pastora Herbicide before seedlings reach 12" in height. For best results on rhizome Johnsongrass, apply Pastora Herbicide when Johnsongrass is from 10" to 18" in height. If treating after pasture has been mowed, treat about 10 to 14 days after mowing when Johnsongrass has 6" to 8" of leaf surface for herbicide to contact.
