Leaves break at petiole

Banana    None Given

I have a banana plant in my yard, about 2 m tall, don't remember the variety, that produces large, beautiful leaves. When they fully extend, the petiole bends and the leaf dies. This plant makes leaves one after the other, they just extend, expand, and break off. No sign of pests or pathogens, at least easy to spot ones. Any ideas? I'm in North-Central Florida.

Hi Kevin - a few images would probably help. Thanks

The question is far too general. At least some pictures of the disorder are needed. Also, information about the environmental and soil conditions would be helpful. What other crops are there in your yard that may carry virus diseases ? Some viruses are symptomless ( or latent ) in some crops until the plant suddenly dies. Testing sap of your banana plant on a suitable host range for viruses may shed some light on the phenomenon observed.

One issue that can cause snapping is fungal damage (brown tissue) or insect damage. But for this we do need images

It is true, fungal damage can cause snapping. But in most of such cases macroscopic symptoms, like yellowing of the leaves and wilting, appear. In the current case the grower does not observe any other symptoms than snapping on an individual plant. Apart from images, it would therefore be helpful if the grower could tell us if banana, planted on other yards in his neighborhood, also exhibit the same phenomenon
