Are there any weed killers that aren't endocrine disruptors or carcinogens?

I'm at war with dandelions, but prefer a few dandelions to cancer or reproductive damage, most days.

This question is probably better suited for the Gardening and Landscaping site currently in commitment phase. You might consider committing to it yourself if you're into working in the yard! – Shane May 30 '11 at 0:18

For a completely pesticide-free way to get rid of dandelions, you'll need one of these.

A bit more work, but if you have as many of them as I do, you'll be able to skip the aerator when you're done.

It's hard work, but yanking them is often the better way to go. – Tim Meers May 30 '11 at 0:33
I tend to use a long knife to cut the weeds well below the surface, and pop 'em out that way. :-) – Dean J Jun 1 '11 at 20:54

I was shopping at the local organic supply store the other day, and was advised to try a concentrated vinegar product. Check out this advice -

Couldn't hurt to try! I am going to!

Preen

See why, check out the MSDS sheet. It shown no registered carcinogens.

I don't think you can preen your lawn can you? The OP didn't say it was his lawn so I'm just guessing. – Tim Meers May 29 '11 at 13:27
"Trifluralin -- Herbicide found in: Preen, Preen & Green, Scotts Garden Weed Preventer, Trefanocide, Treficon, and Trust. Kills annual grasses and broadleaf weeds. Highly toxic to fish and other aquatic organisms. It is a possible cause of cancer and a probable cause of endocrine disruption. It has been demonstrated that it causes reproductive effects, kidney damage, liver damage, sensitivity, and irritation." Unfortunately, not quite what I want next to the garden. :-/ – Dean J Jun 1 '11 at 20:53
