And Roundup is different? I don't think my ounce of clopyralid mixed into
the township's compost heap will make much difference. It is pretty crappy
compost with road gravel. I don't know who takes it for what use. We don't.

Don. www.donwiss.com (e-mail link at home page bottom).

Roundup contains glyphosate. It is much less persistent than clopyralid.
Also, clopyralid is absorbed through he plant's roots. Glyphosate is
absorbed through leaves, so it doesn't matter if there is any in the
compost.

If yours is the only clopyralid mixed in the township's compost then it
won't matter. But if you are using it, maybe quite a few others are too,
and that might make a difference.
