Norris,

What if any techniques are available to intentionally spread the wilt from one stand to another?

Thanks,

Rod Walker

John,
You bring up a great point about the limited spread of Ailanthus wilt
allowing us to recognize what vegetation may follow in it?s wake (and
allowing us to preferentially target female clones). In an act of
shameless self-promotion, if people are interested in some research on
weed-replacement and succession in stands of Ailanthus that have been
treated with Verticillium you can find some of our research on that
subject here:
