a new (month old) plant I bought from the only nursery in Queensland allowed to sell bananas (yep only one). The plants are all tissue culture





Has anyone any idea what the brown spots are? and how serious it might be...

It looks like black leaf streak a.k.a "Black Sigatoka." Here is a link with pictures for more information. Banana Black Leaf Streak Disease in Hawaii

The other members said that it is a manageable disease and have recommended a "Copper Sulfate or CuSO4 Nutritional."

Here is a link to my earlier thread: Blk Sigtka - I officially hate FL

Sigatoka for me, too. Copper sulfate foliar spray!

Where the heck could a month old TC catch Black Sigatoka?????? Where's the world heading?

I've been told by the nursery that it is a common brown fungus problem - - I think they are terrified of black sigatoga - and are trying to call it brown sigatoga

the worst leaf has been removed and disposed of, when the next leaf comes I'll amputate the other leaf and keep a very close eye on it.

the nursery is the only one in Queensland allowed to sell banana plants and I thinkit they are terrified of loosing all of their investent and sole trader rights

If they are a Sigatoka seed there in Australia, so be it! Luckily for me, there's not good humidity and outside conditions for Black Sigatoga to come in my yard.

Something like that happened to me with my Eneste seedlings whan I sprayed them on leaves with cold water. First day that looks like redishs flakes and tomorow they where all black-brown. I think I have pix somewhere.
I cut leaves of and they are pushing new ones now withouth flakes.
Hope that U have same problem.

it's a small world

got an email this evening austrlian time

major point of the email was

Would you be so kind as to post a retraction then to your statement on bananas.com and I will tell our solicitor to disregard the email I sent to him today and we will take the matter no further.

Blue Sky Tissue Culture

I didn't name blue sky as the seller, they've owned up to it and are threatening legal aciton

don't know what the law is in USA ir Europe, but in Australia it is illegal to threaten legal action, the courts are where leagal action is supposed to happen.

BTW sue of bluesky tissue culture, when your solicitor comes visiting they might like to bring a botanist - the plant still has the same fungus, but not as bad as when I recieved it

despite the sellers threats of legal action their advice worked

they suggested taking the infected leaves off the plant as new ones grow - seems to have stopped the infection in its tracks

Just found out today that the Department of Primary Industries is going to do an inspect and destroy on my bananas - - any problems and they will be destroyed.

I asked the DPI official who rang me (at least hey rang to make a time to come around) and they said that Bluesky bananas were the ones who rang them and said I had a problem plant. These are the same mob who have threatened to take legal action against me. Good onya. Nice way to run a business.

The leaves don't look like the link below to the other black sigatoga thread - inspector turned up thursday - not a worry - healthy healthy healthy

The whole point of tissue culture is the avoidance of pests and diseases. I am not surprised that the nursery and the dpi would take such concerns extremely seriously, and so they should, otherwise an entire industry would be at risk.

Lucky that the concerns about a fungus were pure hearsay and have not been validated.

It is normal for young bananas plants to develop some spots on the leaves in cooler weather. CSIRO research noted that some leaf damage can occur at 10 degrees celsius, well above minimum temperatures at ground level in virtually every part of Australia in the cooler months.

Nicolas Naranja

I had similar problems and I think it had more to do with moving my banana out of the shadehouse too quickly.

the Nambour Banana Research Station sent one of their resident biologists to my garden and gave me an extremly positive bill of health. Best cared for lady fingers she's ever seen - because they are massive - and the little dwarf ducasse is exceptionally healthy.

This is the part of our laws where government representatives can invade your private proerty and inspect and either congratulate or poison your plants. No way of saying no, no way of avoiding it, its to "protect" the queensland banana industry
