A couple of my basjoo sometimes do that..I dont know why, they are well fed. It may just beone of those things.

On the second thought I think low temperature plays an important role why the leaves are abnormal and have partial brown spots and maybe nutrient deficiency and maybe bugs play a part but overall all of my bananas recover when the temperature gets higher at night. Now all of those abnormalities are disappearing and being replaced by normal healthy leaves. On some of them, you can't even tell anymore what they have been through.
I guess we are just overly concern because they look ugly and sick.
They are tough bunch.

The brown is stuck together and does not let the leaf unfold and when it finally tears and opens the area dies quickly.

Please HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I'm asking the experts. Is there any chance this is a fungus like Black Sigatoka Disease or any others. I just can't figure out why it is effecting only 2 of my 7 bananas. I now have a second banana that the new leaf coming out has it also. All plants are fert the same and watered the same and get about the same sunlight. All potted plants were potted the same way. With rocks on the bottom and a manure/topsoil mixture. Also it is so far just in the potted plants, it has not affected any of the ones in the ground. Thanks

Tony,

I was doing some research on nutrient deficiencies in bananas in that site I just posted this afternoon (Pest and Disease of Bananas) and I was reading about Boron and Calcium deficiency. I remembered this post of yours. Boron deficiency looks like it could be the problem to me. Check out the site when you get a chance. Here is the link to a Power Point presentation found on that site. http://www.ctahr.hawaii.edu/nelsons/...management.pdf

For the link to the entire site see my post from earlier today. Hope this helps you.

Seems like others have posted with photos of banana leaves with only a midrib and no leaf blade. That appears to be caused by Calcium deficiency (unless you actually see grasshoppers or caterpillars!). Everyone should really check out this web site as it has a lot of great info.

Thank You For The Information.

Thanks Brent ! Good stuff there .The pics of the calcium deficiency match very well to the problems I've had . Every pic of calcium deficiency in fact .
I dug up a few bags of granulated lime and threw it out around em' . Should have worked it in but I'm goin outa town and it's dark out.

Thanks Brent for opening my eyes.

Please tell me what is a good source for Boron and Calcium that you can buy from a plant nursery or store? Anyone?

Bananaman88 · 07-10-2008, 02:18 PM

Calcium and Boron are both considered micronutrients and thus needed in very small amounts. It's usually easier to purchase a fertilizer with micronutrients already added in the proper amounts. Micronutrients can wreack havoc when they are too low and can do the same if they are overapplied.

Thanks Bananaman.
