Roundup contains glyphosate. It is much less persistent than clopyralid.

Stinger is taken in by the leaves. It works its way down to the roots. I
only sprayed leaves, as directed.


I should have made it clear that glyphosate is absorbed only through
leaves and not through roots, but from the Dow information on clopyralid:

" Clopyralid is absorbed by the foliage and roots of plants..."

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.


At $80 a quart* [enough for spraying four acres of crops], and available
only by mail, there aren't going to be any other users in the town.


I suppose that anything that works well isn't going to be cheap. Still,
that quart should last you a good few years!
