They havent been hybridizing, or "chemicalizing" as you put it. The fact is, that out of the 300 or so banana species, major manufactoring companies have only used one species of banana, now that species has a virus attacking it, and they have been using the same banana to the point where they do not have the genetic capability to survive the virus attack.
ProofI posted something on this a long time ago.
EDIT: Its a fungus not a virus... meh
