Bananas face threat from fungal disease. Details here

Bananas, a widely cultivated and consumed fruit globally, come in over 1,000 varieties, with the most common being the Cavendish banana, which makes up nearly half of the world's banana production. However, the future of the Cavendish banana is under threat, raising concerns among scientists.

A fungal disease known as Panama disease Tropical Race 4 (TR4) was initially identified in Taiwan in 1990 and has since spread to over 20 banana-producing nations, including countries in Central and South America, as reported by the Food and Agriculture Organization of the United Nations.

Once TR4 infects farmland, it becomes a formidable challenge to manage. Controlling the disease is not only expensive but can also lead to a complete loss of yield. This soil-borne pathogen is transmitted through infected plants, contaminated soil, and water. However, for long-distance transmission, it relies on human assistance.


A decapitated banana plant is almost useless, an inconvenience to the farmer who must then uproot it and lay its dismembered parts as mulch. But can such stems somehow be returned to life? Yes, according to a Ugandan company that's buying banana stems in a business that turns fiber into attractive handicrafts, as per an AP report.

The idea is innovative as well as sustainable in the East African country. Uganda has the highest banana consumption rate in the world and is Africa’s top producer of the crop. Especially in rural areas, bananas can contribute up to 25% of the daily calorie intake, according to figures from the U.N. Food and Agriculture Organization.

In Uganda, eating bananas is in many ways embedded in local customs and tradition; for many a meal is incomplete without a serving of matooke, the local word for the starchy boiled mush made from banana cultivars harvested and cooked raw.

To harvest the crop, the stem must be decapitated, and in the largest plantations the scene can seem violent after a bumper harvest. The stems inevitably rot in open fields.
