I've been doing a grow in on an athletic field seeded w/Riviera Bermudagrass 38 days ago in Missouri. Been hitting it with ammonium sulfate weekly and most of it is growing in great aside from the weeds and few small bare areas I overseeded 6 days ago which has yet to pop. I've been holding off on a broadleaf treatment for at least another month. I would like to start going after my crab with Drive in the next few days and and take care of the nutsedge at the same time with Manage and also throw in some cheleated Fe. Personally I never have mixed the two together I'd just hate to set back any of my new seed. Any feedback would be great.
