I've been reading up about how Mysore plants are infected with BSV. Should I be worried? Is it necessary to replace my Mysore with a Pisang Ceylon?

Also I should point out that the newest (and only) leaf is chlorotic and has some light green mottling on it as well as being unusually thin and generally unhealthy looking.

I wouldn't be too worried about that. The bananas I have in pots all look really shabby after this winter. Give it a chance. If it looks bad during the summer, then maybe think about replacing it.

Sure looks like BSV to me. Should you be worried? Probably. Will anything horrible happen, aside from the plant not doing great, if you do nothing? Probably not. You probably don't have any vectors to spread the virus, e.g., banana aphids. You might consider giving it more time to see if it improves as conditions for banana growth improve. Or you could kill the plant (like I did with my streaky Mysore plants) and try to get ahold of a Pisang Ceylon.

Fertilizer problem maybe? how often do you feed them? the only issue with one of my plants is the sun damage I just shake it off, it's gonna be warm and sunny for the next week or so. they finally out grew the greenhouse and going through some changes.

Thanks. And I just fed it too, and it's been sunny for a while now. Winter is long gone. None of my other plants are doing this.

Does anyone know if Pisang Klotek has BSV as well?

I am finishing up my contract in the Marshall Islands South Pacific and we have 2 cultivars here, Ice Cream and Mysore. I've had good luck growing the Ice Cream but am batting about 25% on the Mysore. Mysore has been very finicky, and the only thing I have found that helps is to peel the brown dying layer off the psudo stem constantly. Although a beautiful and very tasty banana, they have been tough to grow out here.

One of my original PK's pups had what Gabe and I thought might have been BSV. None of the other pups ever showed any signs though.
Here are some shots of that plant. At the time I thought it was variegated.

Andreas,your plant surely looks like it has BSV. You might want to let it grow a couple more leafs before calling it but if you see this on more,its BSV. Pisang Klotek hasnt shown any clear cut BSV symptoms for most who have it and the markings on Mitchel's plant are not certain BSV either. It could have actually been variegation. The markings on your plant are not variegation though. My single Mysore did that,was IDed as BSV and got thrown out,like Mark did with his. I would say this is the best thing to do even if very unpleasant. Just try again with another Mysore and hope for the best if you like this variety. Thats what i plan on doing. I do have ''Pisang Ceylon'' but i like the ''Mysore'' very much as well.
Any pup you may have removed or any corm,etc you had removed prior your banana growing this leaf has chances of being ok. All ''Mysore'' have BSV in their genome but as long as they are not expressing it,they are safe to have in your collection. Any showing it should go though.

A new leaf just emerged, and the symptoms on that leaf have dwindled. Besides this, I don't think there are any pests that can transmit BSV to my other plants here in California. It is growing, and has gotten really big. I'll wait some more and see how it goes.
Kostas

There are various mealy bugs known to transmit BSV and some do are in CA. 2 species common on citrus have this ability so one does have to be careful even in CA or Greece.
Your plant will continue to grow,it wont die likely and depending on growing conditions,it may produce normal leafs again with only partial or no streaks but that doesnt mean its healed. When flowering approaches its likely the virus will show itself again. If you decide to keep it and see,make sure you keep it well away from your other bananas. If it doesnt show symptoms again for a full flowering cycle or more,i think it would be ok to call it healed and that its not expressing and thus not able to transmit the virus. Unfortunately its not likely to heal from the virus,its relatively rare. If it shows these streaks even in small portions of a single leaf,its still infected,the degree doesnt matter! Keep it away and completely mealy bug free till you decide what to do with it. I cant be 100% positive its BSV as i cant see enough details but check photos for yourself too and decide. It could be malformation from the winter for all i can see in your photos. Do your research and remember that its better safe than sorry.

It's right next to my two healthiest plants, Ice Cream and an unidentified with two pups on it. The newest leaf is almost done emerging, and there are not many streaks on it but there are chlorotic areas and brown, dry patches. It would probably be best for me to get rid of it, but I'll wait a little bit longer. It's still growing pretty vigorously.

If I were to get rid of my Mysore, should I go with Pisang Klotek or Pisang Ceylon?

Whichever you can get! lol
Kostas
06-04-2012, 10:22 AM
Go with both and if you are not too dishearted,try Mysore again too :) I know i will...
I think that once you have Mysore established in the ground for good,the chances are low that BSV will be awaken and start expressing itself and disease symptoms appear. BSV usually awakes following stress yet there are healthy mats in various gardens that are many years old and have seen many winters and other possible stressors...
If you want,post clear pictures of the new leafs of your Mysore and the patterns and post a few leaf underside pictures opposite with the leaf lighted from the sun above to reveal the patterns.

I agree with Mitchel, whichever one you can get. And why not both?
One consideration is height. Pisang Ceylon is described as getting taller than Pisang Klotek, but I don't know if that would be true if they were grown in exactly the same environment. Pitangadiego should know. I'll know eventually, but mine aren't yet at full height.

I've seen Mitchel's pictures of Pisang Klotek, and they appear to be pretty stout. Whichever one will stand up better to the high winds we get here will be my choice. I'd hate to lose a bunch of fruit to winds!

Andreas,post some pictures of your Mysore before deciding what to do,your previous pictures are really not clear enough to call it BSV with 100% certainty. As i told you,we need more and better photos before calling it for certain! Dont doom it before you post them and hear from us!
caliboy1994
06-05-2012, 03:10 PM
I'll get some better pictures up of my Mysore soon. Unfortunately, my camera isn't that great, so it's hard to get high quality shots.
Now, there are some black streaks on an emerging leaf on my Ice Cream. The leaf is also thinner than usual. Is this BSV? Or does it just need to be fertilized or something? All of the previous leaves on my Ice Cream are healthy.

This is not BSV,thats for certain. I would guess its nutritional,possibly Ca. A well balanced fertilizer should fix that within a few weeks,if nutritional.
caliboy1994
06-06-2012, 07:19 PM
I just gave them all a good dose of fertilizer today. Hopefully that will fix it and give them another boost in growth. And good news, I just noticed that my Ice Cream is putting out its first pup! :08:

The water pups that have been coming up from my Ice Cream have developed the same dry patches that my Mysore has. Is this a sign that BSV has spread to my Ice Cream? The dry patches are there already as the leaf is emerging. Besides that, the entire plant is very healthy and growing vigorously.
Here are the dry spots on a Mysore cigar leaf (sorry for the bad picture, lighting conditions weren't that great)

Unless these patches have been a result of rubbing with something on their way out,this is mineral deficiency,Ca if I remember correctly. A well balanced fertilizer should fix it. It also tends to fix by itself in well rooted plants. Do you maybe overwater? I find it difficult to believe your clay soil is missing basic nutrients. I mostly get this defficiency when establishing pups,on their first few leafs and then it fixes itself. I have mostly connected it with small root systems,overwatering anda bit of rot so watch your watering.
'Ice Cream' and the Pisang Awak cultivars many Ice Cream plants end up being,are ABB and thus cannot get BSV.
When you can,post good pictures of all patterned areas found on your Mysore's leafs to see what's going on with it.

Yes, like Kostas says, it has to do with nutrition. I get similar symptoms regularly. In my case, it appears that the problem is Boron deficiency, which is exacerbated by adding Calcium and fertilizing. My suggestion is that you DON'T fertilize at this point. In my experience, that only makes these symptoms worse. Try a foliar spray of micronutrients. Have a soil test done -- it should help you identify the actual deficiency.
The two classic causes of these symptoms are Calcium deficiency and Boron deficiency. The symptoms are very similar and hard to distinguish. And, unfortunately, if you guess wrong about which deficiency you have, adding the wrong nutrient exacerbates the real deficiency.

What Mark said. Over fertilizing can prevent the plant from up taking certain nutrients.
Big Tony is having the same issue with some of his plants and also having issues with the cigar leaves curving (like your mysore) and not opening which I attribute to over feeding. He's going to back off the monthly feeding and see what happens.

I got a bunch of pictures of my Mysore today. Unfortunately, I couldn't get a good shot of the entire plant because of the lighting conditions. The patterning seems to be going away on the newer leaves.

What's odd is that the petioles on the original p-stem were closed while the ones on this new one are open.

I checked the ingredients on the fertilizer I'm using, and it contains boron but no calcium. Therefore I think that I'm probably dealing with calcium deficiency. What should I do about it?

That's not really the way to figure it out. By your logic, my problem would be calcium deficiency, given that I use fert with boron in it, but my plants are clearly boron deficient. You need to have your soil tested professionally. It is rare for our So Cal soils to be deficient in Calcium. Send a soil sample to A&L Western Labs.
