Hello!
I would like to ask you what are the reasons for a pseudostem to start turning mushy and how to stop it. Is it originally a root problem(rot) that makes the leaf bases forming the pseudostem die back and turn mushy like seen in other plants when having serious root rot or is it a topical pathogen affecting them and so removing the affected tissue solves the problem for good?
I have had problems with my potted pups and each time the temperature falls below about 14C,i get progression of the mushy tissue downwards while when the temperatures remain above that and good for growth,the condition remains the same without any worsening and slowly the mush dries up. But the i get rain and lower temperatures again and it progresses again.
I get several types of pseudostem die back. One is the pseudostem has a yellowing one that then turns black. This generally is a slow process and accounts for very little of the necrosis. It doesnt cause much damage.
The second type of necrosis involves the tissues lightening in color and the pseudostem ''cells''/compartments(the macroscopic ones)appearing to get air bubbles in them. As it progresses,this tissue gets mushy and light yellowish. This is of the most aggressive ones and accounts for the most necrosis i get. Many times,when i cut the infected tissue,i see lavender marks at about the point of transition from healthy to tissue with gas.
A third type i see that could well be the same as the above one,causes a stripped appearance on infected tissue,with the compartment walls appear normal color and the in between space appear light lavender at first and then black. It also tends to make the tissue lighter in color than normal or even whitish,like the previous type of necrosis.
The bananas seem to be growing regardless of the above although when they progress,growth slows down some. What do you think is causing the above and what should i do? I removed all affected tissue yesterday except some that is on a relatively new leaf and if i cut it it will be left with a single leaf with no guarantee that it wont progress again....
Thank you very much in advance! :)
