In the mid 1980's I was a speaker at a conference at Purdue. At this
conference a speaker made a presentation about all the chemical treatments
that could be used to control root worms in corn and how effective they
were. At the end of his talk he said almost as an after thought that if
you had a rotation of other crops with corn that root worms were not a
factor in the production of corn. In other words crop diversity would solve
the the problem. So if corn was grown in a rotation we would not need the
chemicals or the Bt corn in the first place. Seems to me like a common
contemporary problem-ignoring ecological principals. How do we deal with
this? We create chemicals and plants that can get around the problem that
was created by mismanagement in the first place and we call this new
technology. Maybe we should approach the problem as a management problem
but we always seems to want the next silver bullet to bail us out of a
problem that could be dealt with in a much easier fashion.
