[MAIPC] FW: Ailanthus control

[Muth, Norris (MUTH)]

John,
You bring up a great point about the limited spread of Ailanthus wilt
allowing us to recognize what vegetation may follow in it¹s 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:
