Always threatened, cavendish banana subject: This article explores the topic in depth.
Furthermore,
Always threatened. Meanwhile, cavendish banana subject:
It is the most consumed and exported fruit to the world: Cavendish banana, threatened by a fungus, may not disappear as announced by some at Middle Long Term. For example, The latest research aimed at saving the species are reassuring, according to a specialist interviewed by RTS.
The variety of Cavendish banana is the most eaten in Western countries. Meanwhile, In Switzerland alone, tens of thousands of tonnes are consumed each year.
The Kaiseraugst banana ripening center, near Basel, sees 33,000 tonnes of this fruit per year pass for the Swiss market. Meanwhile, The bananas treated on the site “come from Ecuador. Therefore, Panama, Peru, Dominican Republic or Côte d’Ivoire”, details Caspar Frey, head of the media service at Coop, in the 19:30 of the RTS. In addition, In total, 95% of them are Cavendish.
Profitable. easily transportable and rich in carbohydrates, fibers and potassium, and always threatened, cavendish banana subject devoid of seeds, the species has all the good characteristics. The entire industry has thus adapted to this variety.

Cavendish monoculture is particularly sensitive. “Each banana is a copy of the mother banana. This poses a problem. because when a variety is sensitive to a pathogen, all the banana grooves,” explains François Lefort, professor at the Haute École du landscape, engineering and architecture in Geneva (HEPIA) and specialist in phytopathology, the study of plant diseases.
Studies on a resistant species
The propagation of the fungal pest being unstoppable. the industry has been trying for years to save the Cavendish. According to François Lefort, studies are about to succeed. This variety “is the subject of work with an existing clone, already resistant to banana fusariasis,” he reports.
