Panama disease (also known as fusarium wilt) is caused by the soil-borne fungus Fusarium oxysporum f. sp. cubense. Panama disease is considered to be the most destructive disease of banana in modern times.
How does Panama disease spread?
The disease is most commonly introduced in infected planting material. Panama disease can also spread over short distances via root to root contact, and through soil. Spread from an infected parent plant into the suckers can also occur. It can also spread with soil and water movement or on contaminated pruning tools.
How do you get rid of Panama?
There is no cure for Panama TR4. Affected plants are unlikely to produce a marketable bunch of bananas, and the plants eventually die. As the fungus spreads throughout the crop, Panama TR4 significantly impacts on crop yield.
How can Panama be prevented?
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 can you prevent banana disease?
Orchard grade mineral oil can be sprayed on the banana every three weeks for a total of 12 applications to control Sigatoka. Commercial growers also use aerial spraying and systemic fungicide application to control the disease. Some banana cultivars also show some resistance to Sigatoka. Black leaf streak: M.
Is Panama disease in banana soil borne?
Panama disease of banana is caused by the soil-borne fungus Fusarium oxysporum f. sp. cubense (Foc) that enters the plant through the roots and colonizes the xylem vessels thereby blocking the flow of water and resulting in total plant wilt.
How do you identify Panama wilt disease of bananas?
Spread occurs through vascular bundles, which become discoloured brown or dark red, and finally purplish or black. The outer edges of older leaves turn yellow. Within a month or two, all but the youngest leaves turn yellow, wilt, collapse, and hang downward, covering the trunk (pseudostem) with dead brown leaves.

How did Panama disease start?
Managing Panama TR4
Panama disease tropical race 4 (Panama TR4) is a serious disease of bananas. It is caused by a fungus that lives in the soil and is easily spread by movement of infected banana plants and planting material, and contaminated soil and water.
Do bananas have a disease?
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.
What is the best fungicide for banana?
Chlorotalonil. Chlorotalonil is a broad spectrum contact fungicide used in banana plantations to control BLSD.
How do you control the fusarium wilt in a banana?
Managing Fusarium Wilt in Bananas
Clean up growing areas thoroughly at the end of the season and remove all debris; otherwise, the pathogen will overwinter in leaves and other plant matter. The most important means of control is to replace diseased plants with non-resistant cultivars.
