Fungus could wipe out Philippine bananas: growers

A disease that has ravaged banana plantations across Southeast Asia could wipe out the Philippine industry in three years unless the government finds a cure, a growers' group warned Monday.

The disease, called Fusarium wilt, is caused by a fast-spreading fungus that kills the plant, said Stephen Antig, executive director of the Pilipino Banana Growers and Exporters Association.

"So far, it has already infected 1,200 hectares (2,950 acres) of banana plantations locally, although that figure can go higher," Antig told AFP.

"If we can not contain this and it remains unchecked, then in less than three years our banana industry will die."

The is the second biggest exporter of in the world behind Ecuador with about 70,000 hectares of plantations, according to the association.

The banana sector is also the country's fifth largest export industry, directly employing 280,000 people, it said.

"Losing this industry will have a huge impact on our economy," Antig said.

The Philippines exports the Cavendish variety of banana, which is the most popular type around the world, according to Antig.

He said the disease wiped out the then-popular Gros Michel bananas in Central America and the Caribbean in the 1960s.

The disease also destroyed Cavendish plantations in Indonesia and Malaysia in the 1990s.

Traces of the fungus were found in controllable levels in the Philippines five years ago, Antig said.

But a more virulent type of the emerged last month and quickly began spreading through in the southern region of Mindanao, where most of the country's banana exports come from, he said.

Antig urged the government to fast-track the creation of a research institute to enable local growers to develop a fruit variety that is resistant to the disease.

The fact is that this problem is caused by the banana industry. The first reason is that the plants are almost all clones, which means that a disease that gets one will get all of them. The current variety that's falling victim to Fusarium is the one that was selected when the original, Gros Michel, succombed.

The probable reason that the Cavendish are now falling victim is that they're using glyphosate (RoundUp), which kills the bacteria in the soil that would normally keep the fungus at bay.

The solution is to stop this madness! Stop the monoculture. Stop the use of most pesticides. Completely ban glyphosate, which is at the heart of the current loss of bananas. The growers simply close up shop and move on to the next banana virgin area that can support the crop. The scorched earth method of farming must end - or we will end.

"Glyphosate is the most used herbicide in the USA.[3] Exact figures are hard to come by because the U.S. Department of Agriculture stopped updating its pesticide use database in 2008."

Pine Pitch Canker, causative agent an indiginous Fusarium sp., kills pine trees in the southern US. An indiginous Arthrobacter sp. secreting an antibiotic, taken up by the pibe tree roots, normally keeps this in check. They need to test virgin soil flora for sp. that inhibit the causative Fusarium. Testing those sp. against glyphosate might also be in order. The growers can use the data to adjust their chemicals, reseed flora, and/ot apply the cultured antibiotic.

I had the fortune of having eaten at least 6 different kinds of bananas, from finger to arm-sized ones. They are all refreshingly different. Sadly, most people don't know the bland crap they are buying from supermarkets are there solely due to the relative low cost of keeping them from spoilage during transportation and storing.
