Italy: Calling on natural defenses to turn back banana pandemic

Tridge summary

The global banana industry is facing a crisis as the Panama disease, specifically the Tropical Race 4 (TR4) fungus, which has mutated and affects the currently grown Cavendish variety, is spreading rapidly. This fungus enters the plant through the roots, causing fusarium wilt, and has been detected in various banana-growing regions, including Australia and Peru. In response, the European Union-funded MUSA research project is exploring the use of natural agents in plant defense by studying microorganisms in the soil around plant roots. The project has identified microorganisms that can help activate the plant's natural defenses and attack pathogens. Additionally, the INDICANTS project aims to develop rapid tests to detect harmful pathogens in banana plants, and the MUSA team is working on commercial biocontrol products and innovations to reach farmers.

In the 1950s, the "Gros Michel" variety of banana was wiped out by Panama disease. The banana crop in some locations was basically eliminated by the disease of fusarium wilt, caused by a pathogen that enters the plant through the roots. With no defense possible, the only solution for the banana industry was to cultivate a different banana variety called the Cavendish, which was naturally immune to Panama disease. In that way, the Cavendish variety rose to become the most traded banana crop in the world today. Unfortunately, the disease that causes fusarium wilt has mutated and now the Cavendish crop is no longer immune. It too is being decimated by fungal disease. "This fungus is a complete nightmare," said Dr. Aurelio Ciancio, from the Institute for Sustainable ...
