I hope that it will be marketed in the Netherlands for biocontrol
of black cherry (European birdcherry, Prunus serotina) by the end 
of this year. After a few years I expect that the mycoherbicide
will be also used for controlling stump sprouting of other hardwoods.

I propose that you invite me to visit your lab and I wiil perform
a field survey and bring you the purple crusts. I have done this a
few months ago on the Island of Nantucket. Scrub oak is a local
weed problem out there. These oaks are overcrowding heath vegetations.
They are now organizing a big research program on biocontrol in Nantucket.
So I can solve all your stump sprouting problems. You just have to send
me a flight ticket and a good compensation of expenses.
You may also want to request a research note that I have available
on disk.
