But don't all the horrors listed in this posting happen in this country too ?

Sure they do, and it's not just with fruiting/edible plants.

For the last few years, here in my little town, I've been noticing a burgeoning epidemic consisting of a double-whammy of bacterial leaf scorch and heavy infestation of gouty & horny stem/branch galls on pin oaks that are fairly quickly taking out large number of these trees in street & residential plantings.
Pin oak(Q.palustris) is a nurseryman's dream - easy to grow from readily available acorns, grows & calipers rapidly, transplants readily as a fairly large specimen, and has consumer recognition. But, when EVERYONE plants one in the yard, and the cities use them almost exclusively as their street tree selection, they've set the stage for virtually unhindered spread of one or more potential pathogens throughout the population.
