Panama disease (or Fusarium wilt) is a plant disease that infects banana plants (Musa spp.).
Why are banana trees dying?
Nearly all of the bananas sold globally are just one kind called the Cavendish, which is susceptible to a deadly fungus called Tropical Race 4, or Panama Disease. If not stopped, Tropical Race 4 could wipe out the $25 billion banana industry.

Is there a disease killing bananas?
Banana bugbear
First identified in Taiwan in 1990, the mould causes fusarium wilt in the Cavendish cultivar. Entering through the roots, it chokes off the plant’s energy supply, killing it from within. This fungus is a complete nightmare for producers.
What is killing my banana plant?
Nematodes: Nematodes are a common banana plant pest. They cause rotting of the corms and act as a vector to the fungus Fusarium oxysporum. There are a number of different species of nematode that like bananas as much as we do. Commercial farmers apply nematicides, which when properly applied, will protect the crop.
How do I save my banana tree?
Give it a good watering in the spring to encourage new growth. It may not get as big as a plant that overwinters with its stem, but at least it will be alive for a new season. Hardy banana tree types will normally come back fine but may need pruning of any dead growth if it was left on.
What is going on with bananas?
But a new strain that emerged in the 1990s is now attacking Cavendish bananas in Malaysia and elsewhere in Southeast Asia. The strain, called tropical race 4 or TR4, was also found in Colombia in 2019 and Peru in 2021, sparking concerns that the world’s entire banana crop may be at risk of extinction.
What is the best fungicide for Fusarium?
Universities have recommended using group 3 fungicides Prosaro (prothioconazole plus tebuconazole) or Caramba (metconazole) applied at early anthesis (Feekes 10.5. 1 or flowering) or within the first six days after flowering to combat Fusarium head blight.
Is banana fungus harmful to humans?
Mokillo, moko, and blood disease bacterium are bacterial diseases that can also cause red discoloration in bananas. While unappealing to eat, these diseases affecting bananas are not a threat to human health, however when in doubt, throw it out or compost them.
What does Panama disease look like?
yellowing of lower or older leaves, caused by the fungus blocking the water conducting tissue within the banana plant stem. lower leaves collapsing to form a ‘skirt’ around the plant. cut open, the stem is discoloured from yellow to red, through to dark brown or black, depending on how long the plant has been infected.
Is the Panama disease coming back?
Today, 99% of exported bananas and nearly half of total production worldwide is of the Cavendish variety. But this strength has now become the banana industry’s greatest vulnerability. Panama disease has returned, and this time the Cavendish is no longer resistant.
How can we prevent Panama disease?
Prevention and farm hygiene
Use clean planting material, such as tissue culture plants. Avoid sharing farm machinery and equipment with other growers. A common way of spreading Panama disease is in soil attached to equipment. Wash and disinfect all machinery, equipment, vehicles and footwear before entry to the farm.
How do you treat banana wilt?
The early removal of the male flower bud that attracts bees and other insect vectors that carry BXW bacteria; Single diseased stem removal (SDSR); and. Disinfecting metal tools with fire or a sodium hypochlorite solution to keep the disease from spreading to healthy plants.
How can banana disease be controlled?
An integrated approach appears to be feasible in management of banana disease that includes use of improved/resistant cultivars and disease free planting stocks, judicious use of pesticides, irrigation water, removal of diseased plants and plant parts, proper sanitation in plantation and a close monitoring of the
Will my banana tree come back?
Although they freeze back to the ground each fall, with proper care they will resprout in the spring. Hardy bananas grow fast enough to match their previous year’s size by early to mid summer, and it usually only takes about two years for a young plant to reach its full size.
What is the best insecticide for banana?
Vayego Forte is an innovative insecticide that controls banana weevil borer in bananas. The active ingredient tetraniliprole, acts by inhibiting ryanodine receptor modulators in insects. Vayego Forte affords a new mode of action for growers looking to control banana weevil borer in bananas.
Should you cut dead leaves off banana trees?
You should trim dead leaves off of a banana tree to encourage growth and maintain a beautiful appearance. When a banana tree is not getting enough water, leaves can become dry and turn brown, and they cannot be revived.

25 years
Banana tree – 25 years.
What is sigatoka disease?
Black Sigatoka is a leaf spot disease of banana. It is an important banana disease in many countries around the world. Severely infected leaves can die, significantly reducing fruit yield, and causing mixed and premature ripening of fruit bunches. It is not present on mainland Australia.
Why don t bananas taste like they used to?
Then along came Panama disease, a fungus that has been the bane of banana growers since the 1800s. It all but wiped the Gros Michel off the planet by the 1960s. As the fungus decimated crops, a less-popular, less-flavorful variety—the Cavendish—was discovered to be resistant to the pathogen.
