In case you haven't checked, genetically resistant fruit has the
pesticides built in genetically like permethrin, the neurotoxin that
occurs naturally in chrysanthemum flowers. In fact the genetic
varieties splice genes from plants such as chrysanthemum to the desired
plants.

Not all disease resistant plants are this way. The technology you mentioned
is relatively new. There *are* plants which were simply selected because of
resistance, less or a proactive process than the one you're describing.

But these disease resistant plants have something that the others don't,
a chemical. Call it what you want, but it is either a preventative or
curative chemical. It is part of evolution. Plants which have genes to
produce a chemical that aids survival survive and the chemical with it.

This is not the case for commercially available tree fruits. All varieties
that exhibit resistance to insects, fungi or bacteria have been produced by
standard breeding techniques. If you know of an example that was not
produced by standard breeding please enlighten us.

That is only true in the USA and other countries that are paranoid by
Genetically Engineered fruit. Examples:
