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

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