Hi there, folks. Recently I saw a discussion -- may have been on this
list; may not have -- about the herbicide called clopyralid.

http://en.wikipedia.org/wiki/Clopyralid

Apparently it persists for a long time in soils, unlike a lot of other
herbicides, and has caused problems for many large composting operations
in the States. It's especially nasty for Asteraceae, Fabaceae, and
Solanaceae, three of my favourite plant families.

Anyway, my question is this: do you think that leaves raked from a lawn
that you suspect has been treated with clopyralid (it was given a
weed-and-feed spray in early summer) would cause any problems in compost
or sheet mulch? There are so many leaves in my townhouse complex, and
it'd be a shame to not use them.

Thanks in advance,
Paul d'Aoust
