I think you are right: Understanding and making use of the principle
at work (evolution) is more important than identifying the specific
mechanisms & organisms that made your potatoes resistant (and both
microorganisms and the genetics of the potatoes are probably at work
But Larry is right too regarding the need to be aware of which
microorganisms are beneficial for pest and disease protection and so
am I regarding the need to understand the conditions under which
each one thrives.

One).- No one can (or should) patent natural biological processes (or
for that matter, living organisms - and that is exactly why those
whose chief concern is personal rather than public's benefit shifted
their efforts to GM crops - so they can patent them; disregarding
their effects on the environment, public health and non-GM farmers).
Two).- My chief concern is simply: Change the basis of the nation's
dominant agricultural production system and therefore, the way
agriculture in general is practiced.
In order to accomplish that goal, we need to develop a standards
based approach. Your faith was generated &/or reinforced by your
understanding of the biological principals that in turn,
demonstrated the validity of that faith and approach.
Where I am, few farmers share your knowledge so we have our work cut
out for us when organizing evaluation and demonstration projects.
Most importantly, resources for sustainable rural development
projects of this type depend on our being able to present principles
backed by data derived from replicable experiments carried out by
accredited universities and research institutions somewhere in the
Based on those historical events, we can obtain financing from
sources that provide a results dependant pay back scheme (IOW, the
risks are shared). Obviously, solutions that generate positive
results in one place and time may not be applicable to another, but
a knowledge base that helps our understanding of those differences
and permits us to foresee prepare for pests, disease and
deficiencies and will develop with time.
As you can see, this is not a trivial goal and frankly, I am
somewhat disappointed in the lack of response from those involved in
the academic and governmental research loop.
I am also unaware if my principal post appeared on sanet (if it was,
I never received it - Lawrence got a copy off-list - and even the
self bcc didn't come back - it may be my ISP or gmx).

Thanks John. As always, your valuable and relevant input is highly
I'm sure you agree that the meaning of "getting rich" depends on
one's health, values, family and contribution to (and role in)
