We do have a post-emergent product that can be used in your lawn for clover. Depending on the type of fescue you have, this product can be used at the time of seeding. Drive XLR8 Herbicide is a very good product that is labeled for clover, as well as various other types of broadleaf weeds. It is safe for use in fescue as well. If you are overseeding with fine fescue, it is recommended that you use Drive XLR8 at least 7 days before seeding or 28 days after emergence of the new seed. If you are overseeding with tall fescue, Drive XLR8 can be used at any time. We do recommend using an MSO surfactant with this product as well. Please check the label with regards to this.
A pre-emergent can be used at the same time as a post emergent. Prodiamine 65 WDG is a very good option. It will prevent many broadleaf and grassy weeds from emerging.

In southern states, individuals should be using this product in late February or early to mid March depending on the soil temperature.
We would also recommend checking out our Warm Season Lawn Schedule as well. This gives very good information on when to fertilize, use pre-emergents, etc. in your lawn.
Drive XLR8 Herbicide Crabgrass Killer could be mixed with Resolute 65 WDG as long as you follow the instructions on both product labels. However, if you are already seeing weeds it is too late for any pre-emergent to be effective.
