Panama Disease is among the most destructive banana diseases, affecting particularly Cavendish bananas, which are half of all bananas produced globally. The traditional method of treating Panama and Moko disease has been to treat the infected plantation with insecticides, then chop and burn the infected crops. But in the 1950s, the crop was swept by a strain of Panama disease, also known as banana wilt, brought on by the spread of a noxious, soil-inhabiting fungus. Panama disease TR4 is considered one of the most destructive diseases of banana plants worldwide. The second comes from a more unlikely source: nematode worms. Without a cure or treatment, there was no way back for a plantation once the disease had taken hold. (PNA). There are occasions when organisms need some cells to sacrifice themselves. Panama Disease in Banana: Multi-level solutions for a global problem. This allows the creation of otherwise impossible infertile hybrids. In the banana’s case, the plant still produces fruit but can’t make seeds. A hardy hybrid of wheat and rye called triticale was made in this way. But, even with a solution to TR4, how long will it be before the next disease takes hold? Banana Fusarium Wilt Symptoms. Modern bananas can’t even grow seeds. During the 1950s, a first outbreak of Panama disease almost wiped out the commercial Gros Michel banana production. These plants are not very useful commercially because they are fertile so they produce seed-filled bananas. Disease remains viable in soil for decades – no effective treatments currently available. So they must have learned to look out for these fortunate accidents and cultivate them, preferring them to their wild and seedy relations. Our team has tried rehabilitating a farm with only 30 percent left in population,” he added. The earliest known discovery of Panama disease was actually in Australia in 1874. This was the situation facing the banana industry in the 1950s, when Gros Michel plantations around the world were being overwhelmed. It worked for a while in Australia, which has very strict rules to prevent foreign soil entering the country, but even there the defenses were breached in 2015. Unfortunately, it’s not necessarily that easy. For a while, the banana companies carved new plantations from untouched rainforests. The most commonly used practices include mostly sanitation and quarantine practices to prevent the spread of Panama disease out of infected fields. It is a wilting disease caused by the fungus Fusarium oxysporum f. Pathogen is resistant to fungicides and until now, its control is limited to phytosanitary measures. Only two or three plants of every 10,000 show promise, but after many iterations, they now have a Cavendish line with some ability to withstand TR4. Eventually the trees dried out completely and died. The Cavendish banana may have had a remarkable journey from colonial curiosity to global staple. A slightly more radical approach is to try to evolve plants resistant to TR4. However, lessons about how to solve this latest crisis may lie in the last outbreak of Panama disease, where an answer came via an unlikely source. 2000 Oct;90(10):1173-80. doi: 10.1094/PHYTO.2000.90.10.1173. A minute amount of tainted soil can carry the disease to a new plantation where it remains infectious for decades, immune to any chemical treatments. Occasionally, cells are produced that have two copies of each chromosome instead of one. Then they started to curl and wilt. Fusarium fungi block plants vascular system (Phloem), depriving the plant of the necessary minerals, nutrients and moisture, thus causing it to turn yellow until it dies down.
