Question about Allelopathy

A Question from a Forest Makeover Participant: I've read and witnessed that tree of heaven (Ailanthus altissima) is allelopathic. I'm getting quite a pile of sawdust and planer shavings from it and I'm not sure, is it ok for composting and garden paths or is the wood toxic to other plants?

First, some background on allelopathy (from wikipedia). "Allelopathy is a biological phenomenon by which an organism produces one or more biochemicals that influence the growth, survival, and reproduction of other organisms. These biochemicals are known as allelochemicals and can have beneficial (positive allelopathy) or detrimental (negative allelopathy) effects on the target organisms. "

In researching this question, I came across a very interesting article. http://arnoldia.arboretum.harvard.edu/pdf/articles/473.pdf

After reading this article, I would tend to think that the shavings and sawdust from ailanthus harvested and sawed during the growing season (when there's a lot of sap and most likely ailanthone present in that sap) could be toxic or injurious to other plants growing in the area. So I would probably avoid using it as a mulch in the garden. However, there may be some benefit to using it on a trail or pathway where you wanted to keep the weeds down, and there aren't any plants you'd especially like to keep nearby.
