irapeanum first attempt

[dodidoki]

I got 2 "bigger " and one tiny protocorm fom Jan , many thanks, and for advice. I saoked with RO water from agar andn put them into seramis, akadama anad lava rock mix. Jan advived 5% chopped sphagnum but i left it because of danger of infection. I soaked boiled mix and after haeting soaked with Amistar ( equivalent with Previcur). I hope it will establish and I will see its flower within 10 years.....

cross fingers for you

 

[polyantha]

Hope they will grow. That would be awesome!

 

[silence882]

Good luck! It would be great to have these in cultivation.

We should try to get the product "Verdera Prestop". There is Gliocladium catenulatum (fungus) in it, its a biological fungicide. It can colonize the Cyp. irapeanum roots. Perhaps this is the key to grow this very difficult slipper orchid.

will ask a friend if he can get this for us

.. its a biological fungicide..

The young seedling is killed by bacteria not fungi after deflasking I fear.

 

[polyantha]

Antiamoebin (AAM) was extracted from this fungus too. It is an anti-microbial polypeptide.

I tested Mykotown from Biotechnology AG but couldn't find any positive effects in plant protection

 

[polyantha]

Did you test the Mykotown on your irapeanum?

 

[Berthold]

No, on Cephalanthera damasonium and Orchis pallens. That are species with similar problems.
But the tests were not very consistent and intensive. If I would be younger I would have to repeat the tests.

good luck dodidoki, it could be you who is the first...
For others like me I'm waiting for a hybrid cross with good flavum.

Rhizoctonia solani is a fungus that was found on Cypripedium irapeanum roots. This is perhaps the fungus that delivers the energy for the plant to start growing after deflasking? We could try to get it...
