Many people falsely believe that putting eggshells at the base of their tomato plants cured BER because they didn't perform a controlled experiment. Had they performed a controlled experiment, they would know that the problem went away on its own.

I live on and grew up on a farm. I see the benefits of foliar spraying every day. Farmers no longer apply fertilizer to the ground, but use foliar spraying every 2 weeks with herbicide, fungicides, insecticide, and fertilizer All at the same time.
There are plenty of University studies proving the benefits of Foliar spraying. In regards to banana, there are specific recommendations for using foliar spray to treat nutrient defectiveness. Just use google to find them.
So why don't YOU perform an experiment proving it doesn't work!

Oh, egg shells are a good source of usable calcium to the plant, but lack of calcium is not the only cause of BER in tomatoes. Calcium is the 'truck' to transport many other elements though the plant. So when calcium deficiency is suspected, you can bet several other elements are needed too. ... One can overload a plant with calcium too; which can cause a blockage of root uptake of other needed plant elements.
