Tenacity, Tons-Of-Dandelions, and Overseeding?

[kmcdok]

Hi all. I have a lawn that's probably 30%-40% weeds. Literally, there are parts of the yard that are majority weeds - lots of dandelions. Other parts, however, are pretty well established with Bermuda with some chickweed and sporadic other weeds. We have two inside/outside dogs, so I hate to totally kill everything off to dirt/mud. Can I spray Tenacity and seed at the same time on top of what I have? If so, do I use surfactant? I'm a super novice. If it's recommended to go this route, won't a fair amount of the seed just land on the dandelion leaves instead of falling to the dirt? Am I worrying too much and should I just go for it?

Thanks
Ken

Tenacity is NOT for use on Bermuda. There is only one exception to this, and that is for using it when the Bermuda is 100% dormant.
