Soil weed comtamination

What types of weeds have you found in purchased topsoil? In mulch?
Nutsedge? Bermuda? Quack grass? Canada thistle?

How can you avoid weed contamination?

Unfortunately, all topsoil (unless bagged) is full of millions of weed seeds. To answer the question, about everything. About all I do, is depend on quinclorac. It takes periodic aps, but is necessary. Of course now, at this time of year, it's not so bad. The grass will grow and harden off, so the results in this short seeding time will be the same as those we meticulously labored over all summer long for new growth (yeah, I put a lawn in in June lol).

I went through 15 yards at my house and it seems Nutsedge and Canada thistle are my worst culprits. I may pick up some Drive this weekend

I guess I should be pleased with my construction yard... no real weed problems in their top soil and no problems in their compost...
