If it rained less than 4 hours after applying Tenacity Herbicide, you will need to reapply, but wait until the area has dried. Tenacity Herbicide is labeled for Yellow Nutsedge so it should work if that's what you have, just make sure to follow the label instructions. Sedgehammer Herbicide is definitely a great solution for nutsedge. According to the label you may overseed with annual or perennial ryegrass or bermudagrass, 2 weeks after application. All other seeding can be done 4 weeks after application. If you plan to aerate, you can do it 3-4 weeks after application as well to avoid stressing your grass.
When mentioning Tenacity Herbicide and temperature, we are referring to the temperature at time of application. If it gets above 70 degrees after your application has dried, that is okay.
Tenacity Herbicide is not labeled for Japanese stiltgrass. We generally recommend using Acclaim Extra Selective Herbicide for Japanese stiltgrass. Be sure to check the label to make sure your turfgrass is tolerant.
