Is there a better product for killing Johnsongrass in pastures?
Unfortunately, Halosulfuron Pro Herbicide is not labeled for Johnsongrass and it has been replaced by ProSedge Herbicide, which is also only labeled for some broadleaf weeds and Nutsedge. Johnsongrass can be a nuisance and hard to get rid of, unfortunately, there is no chemical labeled for it in pastures. You can mow it as low as possible and/or apply a Glyphosate product such as Roundup Pro Concentrate to spot treat but even then you might only get suppression. We would also recommend contacting your local cooperative extension office and speak with a Master Gardener to check if they are aware of a successful product.
