That's different. 35, 50, 65l. But for example, the first (Ichimaru) are two plants in two 20l containers. The last Primosole has a 65l container. This is the maximum for me (containers have to move over 4 steps)

I have the same problem with Meyer lemon as you (http://tropicalfruitforum.com/index.php?PHPSESSID=ef5496e71cab6e84e61e7450a2ae1b6d&topic=25303.msg296238#msg296238). I was hoping somebody could advise. I also do not know what it is. What is it? And what about it? In some features it's very similar to Greasy spot, but Greasy spot is (probably) not.
My Meyer was without these symptoms from 1984 until 2010/2011. From 2011, it appears in the second half of the year regularly. It attacks only old leaves or twigs, new additions are flawless. For these reasons, I think it's a fungi (But at the same time it does not spread to other citrus trees. That's weird). I have tried all the available fungicides, but without success (The EU market is heavily regulated, really effective means can not be bought at all, they are forbidden, and there is a need for special registrations and permits for that). Recently I managed to get a little non-selling fungicide (active substance: cyproconazole 160 g / l + trifloxystrobin 375 g / l). I will try it next year. It's my last hope.

Snek, I had very similar problem with my Meyer lemon. I've read somewhere it's called plant's edema (or oedema), and that it affects only plants in pots. It is said to occur when roots take the water too fast, so that leaves can't transpire it and they get damaged.
I don't know if it's really the edema, and why it occurs only on Meyers. In my case, similar as in yours, the disease didn't spread on any of my other plants. The Meyer's tree eventually lost all leaves and died.

By the way, you have really impressive plants, Snek. :D

Snek your trees are looking great. Do you have them in a green house year round or moving in and out through the seasons? What kind of material are your container? I would love to get my trees to fruit like that.

Ahoj Sneku, pictures are great. Congratulation.great effort. It is good to let people all around the world  know about Czech citrus industry which is very promising especially in latest years thank to global warming.In Czech republic we have very favorable conditions for growing citrus trees. No greening disease, no fruitfly, hot days (around 10 in a year) and cool nights (around 350 a year) .  Our local delicacy - green fresh frozen oranges - is unfortunatelly little underrated so far but we can supply all around the world especially during november and december. Regarding your great pictures i can see bright future for our mighty Czech citrus industry.Btw what fertiliser do you use for your citrus trees? urea, organic manure or any industrial chemical manure?

Hi Snek,
About tmy meyer lemon, I got a few suggestion from different persons. Some said is oedema, some said a kind of fingus. I tried to water and fertilize less in case it's oedema but the situation didn't improve. I tried different fungicide and didn't see any improvement. Like yours, my meyer carried the symptom on older leaves and limbs and shred a lot of those infected leaves. Finally, I sprayed it with a product called "end all" and the shredding stopped. Do you think that it's spme kind of mites?

Snek, your trees are spectacular. What amaze me it's the proportion between the tree size and the container. I always thought that to have trees that big the container ahould be lot bigger. Do you root prune these trees? If yes, how do you proceed? Thank you so much for the information

To Mtlgirl:
"Do you think that's spme kind of mites?"

No. I still think it's some kind of fungus.
Here's the photo in high resolution: http://tropicalfruitforum.com/index.php?topic=25303.0

Too large containers are always a big problem for citrus trees in a cold climate. I'm working better with smaller containers. I have more control over the humidity in the flower pot and others.
In the spring, roots swiftly grow into loose soil under the containers. That's what my citrus always encourages.

It is very common in Eastern Europe and there it is called "Meyer disease", only Meyer lemons are affected. Fungicides are not working, no radical cure has been found up to now.
Best regards,

Ilya, I do not know whether you are placing the Czech Republic in Eastern or Central Europe, but here is what you write no one knows. I do not think of myself, but also of other growers who are my friends. (you probably know - Petr Broza, Zdeněk Černoch and many others). Besides, I am the moderator of a Czech forum devoted to citrus growing. "Meyer's disease" I hear really for the first time. Meyer has a number of various problems in Eastern Europe, but this is new, quite different. For me totally unknown.

But I do not know it does not mean it does not exist!!


Symptoms on my Meyer (EU-Czech Republic) are similar of matt_citrus (USA, Los Angeles) and Mtlgirl (Canada).

I have been growing citrus since 1981. My oldest Meyer is from 1984. I have 4 diffrent Meyer plants. Until 2010 they were all without disease. Since 2010, all of my Meyers have been reported to be ill.
Appears exclusively in the second half of summer. Is only on old leaves, never on new additions. It does not spread to other varieties of citrus.
Plants only significantly weaken, but will not die.
Testing fungicides had no effect at all.

At the same time, it must be said that effective fungicides are forbidden in the European Union. Or they are subject to strict regulation. For normal humans they are inaccessible. You know that.
I managed to get a bit of a highly efficient fugicide subject to regulation. I will try it this year. It is (cyproconazole 160 g / l + trifloxystrobin 375 g / l).

This "Meyer disease" belongs together with the hybrid (unshiu x P.T.) ITSZ Prague among my two biggest mysteries about citrus.

Snek,
It is widely discussed on Russian and Ukrainian citrus forums, the symptoms are very similar to yours,   if you can read Russian, here is one extensive topic on this disease
http://forum.homecitrus.ru/topic/10267-bolezn-zhirnye-piatna-bolezn-limonov-mejera/
Best regards,
                       Ilya

Ilya, thank you for the link.
Russians have been taught at school all the time before 1989, but I do not know Russian. But the computer translation from Russian into Czech is very accurate. Which can not be said about translation from Czech to English.

Meyer's disease here means Greasy spot.
Proroblem is that the majority of photos in the link are not publicly visible. Any visible photos - there is no any Meyer's disease or Greasy spot , but simple cultivating bugs in citrus growing in pots.
What is on not public visible photos I do not now. It can be the same disease as me, but it may be Greasy spot.

I know Greasy spot. It is unfortunately found on my citruses (Laboratory Confirmed, Not By Me, By Dealer). The most infected is tangelo BA-9, which is and has been a major infection with me. 5 other plants are affected poorly.
The infection at Meyer begins to appear at about the same date as Greasy spot. In the early days it looks similar. Meyer's disease and Gresay spot attack only the older leaves. However, similarity with Greasy spot ends.
Greasy spot passes into gray shades and looks like something greasy on the leaf. At Meyer, it turns into an orange color and looks more like iron corrosion. Rust. Threatened leaves at Meyer completely dump within 2-3 weeks, with Greasy spot held in the tree for more than half a year and fall out and in the spring.

Snek,
You see,  the link above is on the 11 page topic on Meyer disease with 218 posts.
You are right, it starts with a description (  a translation from English) of citrus Greasy spot disease.
In the following discussion people share their failed experience in treating it with various fungicides and mineral oils ( to prevent new spore germination) as well as on the absence of  contagion infection of nearby citruses, a unique features distinguishing it from Greasy spot.
Viral hypothesis as well as environmental factors are discussed with no conclusion. Apparently it is not  lethal, most of plants recover , but intermitting character of the affection does not permit to fully get rid of it.
Best regards,
                       Ilya

Yes I know, I read everything. Otherwise I would not know that there are some visible photos without registration  ;)
Ilya, without photos, just from the text, I do not know if she really talks about the same disease as my Meyer's or about Greasy spot or something else.
On public visible photos is not diseas, is not Greasy spot. Some contributions describe it in the winter - it's not the same disease. That fungicides do not work is also not a clue because the fungicides available to Greasy spot do not work. I mean available fungicides in the Czech Republic. In Russia it will be the same. Why? Because nobody sells them, because they have only a minimal outlet for them. Because there is another climate and such diseases are not commonly found here.
The only thing I can buy against Geasy spot. It are fungicides on base copper oxychloride. It will not cure Greasy spot, it will only temporarily restrict it. But neither of these do not have any effect on my Meyer's disease.
