Bordeaux mixture's pretty nasty stuff, but it's been used on many types of fruits for a couple of centuries, not just bananas. It's also generally approved for use for use in organic growing so it's not easy to avoid - buying organic may actually increase the chance it was used on your fruit.

Bordeaux Mixture is relatively benign. Copper, Sulfur and Lime are all naturally occurring chemicals, which (as you say) have been used to fight fungus for hundreds of years.

Not all "chemicals" are evil.

A while ago Monsanto ran a series of condescending ads whose tagline was "without chemicals life itself would be impossible"
