This time of year, because plant growth has started to slow down, some weedkillers are not so effective. I would tend to take a belt and braces approach and spray - wait a couple of weeks for it to take effect then dig out the roots and apply the manure after. Depending on what weeds you have unless the roots are removed they will still pop up next year saying "thank you" for the manure. I have been using roundup this year and it has been a help but the brambles survived it and while it "discouraged" the bindweed - it did not kill it all.
Good luck!

Cover the ground with cardboard, then spread the manure, then cover with weed membrane. The cardboard blocks out the light but will slowly rot down. Remove the fabric in spring and the worms should have pulled a lot of the manure down into the soil.
