Banana plantations in Colombia threatened by deadly fungus

The transcript discusses the spread of the TR4 fungus in Cavendish banana plantations, highlighting the genetic vulnerability of these bananas due to their monoculture nature. TR4 spreads through infected planting material, soil, and water, disrupting the plant's vascular system and halting fruit production. The fungus is difficult to remove from soil, as fumigants and fungicides are ineffective.

What is the primary disease affecting Cavendish banana plantations?

Explain the concept of monoculture in relation to Cavendish bananas.

How does the TR4 fungus affect the vascular system of the Cavendish banana plant?

What methods are ineffective in removing the TR4 fungus from plantation soil?

Describe how the TR4 fungus spreads in banana plantations.
