What is killing the bananas?

Panama disease (or Fusarium wilt) is a plant disease that infects banana plants (Musa spp.). It is a wilting disease caused by the fungus Fusarium oxysporum f. sp. cubense (Foc). The pathogen is resistant to fungicides and its control is limited to phytosanitary measures.

Why are banana trees dying?

Banana tree leaves that are turning yellow and dying indicate that the tree is not getting the nutrients it needs. Inadequate fertilization, poor-draining soil, overwatering and fungal infection are some of the common reasons a banana tree (​Musa​ spp.) might lack nutrients.

The fungus, which can live undetected in the soil for decades, enters banana plants through their roots and spreads to the water- and nutrient-conducting tissue within, eventually starving the plant of nourishment.
