So this is my first bunch of bananas, my pride and joy.They are goldfinger variety and I live in Rancho Cucamonga in southern ca. Within the last week they have started getting black spots on them? Any suggestions on what this may be?

Yea I believe it might be from the cold, it had dipped below the 50's a few times. I just wanted to see if anyone has seen this personally. Thanks for the responses.

I have spots on my goldfinger bunch also. I believe it is caused by a fungus called Deightoniella torulosa . It seems that bananas that are shorter and shaded suffer most from this problem. The disease is named fruit speckle.

So have you found anything that can help rid the fungus or I even prevent it next time around?

If it is a fungus, removing the flowers from the bunch can be helpful. You can also spray the bunch with copper. Finally, I have had a lot of luck with bagging my bunches in frost cloth.

Copper fungicide spray should be very effective.

I guess it could be caused by cool temperatures, but I only see spots on banana
bunches that are shaded which leads me to believe it is a fungus. This time of year the days are short and the sun declination is lowest so it would seem to be more favorable time for fungus problems.

Not directly, a very small amount of copper will be taken up as plant nutrient, but it will be used by the entire plant. Copper is a protective fungicide, it inhibits growth of fungus and bacteria on the surface, it doesn't have systemic action.
