DIY formula.  http://tropicalfruitforum.com/index.php?topic=3239.0

FWIW it's worth, been using root tip pruning systems for decades.  Copper paints are about the best.


Thank you Mark, actually that was the thread from which I got the info. I found more info about it, see below ;)

Copper sulfate and ammonia (to make CuOH2) though that would be a pain  :P

Both CuO and Cu2(OH)3Cl should put a dent in fungi and prune/suppress roots. No idea if you would want to use them or not and this isn’t advice to do either. I would lean towards copper oxide being ok, see if you can find anything on it being used. How about copper carbonate?



You were right Ulfr, I think that all 4 of them would work. I follow your tip and searched for info and I found a patent which explain this:

"Preferably, the water-insoluble copper compound is in powder form and selected from the group consisting of copper oxychloride, copper oxide, copper carbonate and copper hydroxide.The particle size of the compound in powder form is preferably in the range of 0.5 to 2 microns. Suitable copper compounds meeting the above requirements are commercialized by GRIFFIN CORP. under the trademarks KOCIDE 101 or SPIN OUT FP. These compounds contain proprietary ingredients enhancing the dispersion and activity of the basic copper compound, which is preferably copper hydroxide. As aforesaid, the copper compound acts as a growth regulator by chemically pruning the rootlets and radicles that come in contact with it.

Here the patent: https://docs.google.com/viewer?url=patentimages.storage.googleapis.com/pdfs/US5575112.pdf

Now I must find out how much copper oxychloride (which is the easiest to find here) I must add to one litre of latex paint to make it work.  :)

Thank you both.

You can use 'Kocide 101' manufactured by Dupont, which might be available in Spain. This product contains 77% Copper hydroxide.

Not for sale in EU either :/ Thanks. I have Copper oxide and Dicopper chloride trihydroxide, but I don't know if they have the same properties than hydroxide.

Thank you Simon for the reminder, I found very interesting this paper. I see there are some products in amazon here in Europe that maybe are the equivalent to those that you use in America:

https://www.amazon.co.uk/dp/B0064N1GH8/ref=sspa_dk_detail_4?psc=1

https://www.amazon.co.uk/dp/B01AB0G2EQ/ref=twister_B01EXAACEQ?_encoding=UTF8&psc=1

Are they the same?

Jose, how much finished product are you wanting to make?

Enough to paint about 50 pots, 1.5 galons each.

Ok got it.....there are lots of posts here about root pruning paint so you've probably already read about MicroKote...You can check their website but from my experience with it, a little goes a pretty long way. May be easier than trying to make your own since you don't need a ton of it.

Problem is that Microkote is not for sale in Europe. So apparently I don't have other option that to make it myself or buy paint for ships. :-\

I just bought a 4 pound bag off ebay .

Thank you Bananaizme. Could you give me the link so I can check shipping cost into EU?

Hi,

I'm trying to find Copper(II) hydroxide here in Spain to make my own paint and is being way difficult. Shops don't sell less than 5 kilos for 45€ and you need a professional card of pesticide manipulator (which I don't have) to purchase it. There is any other copper fungicide easier to find that can be use as an alternative to Copper Hydroxide to prepare the paint?

Thanks for your help

Good luck with them. A good loquat in its point of ripeness for me is one of the best fruits. I found more info about Peluches, is an average variety regarding flavor. If you find Rolhao II let me know!

Hello my friend, do you know any Spanish nursery that sells them? Thank's!


Si, eu comprei o meu Tanaka aqui: http://tienda.agrologica.es/comprar-planta-vivero-frutales/496-nispero-tanaka.html Boa planta e bom preço.

Anyway I'll prune mine several times this year (it's still in formation) so if anybody needs scions I should have by the end of this spring.

Golden Nugget is considered a middle quality variety here. Big Jim dind't appear at this side of the ocean as far as I know.
Thank you very much my friend! Do you think that Tanaka variety is best than Peluche? Thank's!
https://www.canarius.com/en/plants/eriobotrya-japonica-cv-peluche.html


Peluches is an average one, far from Tanaka, it's closer to Argelino. All of them ripen in different weeks, so it's interesting to have that in mind. Better than Argelino and Peluches is your Portuguese variety Rolhao II, that ripens about the same time than the former. According to this pdf, it's excellent: http://www.publicacionescajamar.es/pdf/series-tematicas/centros-experimentales-las-palmerillas/innovacion-en-el-cultivo-del-nispero.pdf I'd like to find it to make the season longer with top tier varieties.

Thanks Jose. Very interesting. Could you share a little details on how veneer grafting was done? Did you align the vascular layers?

I didn't align anything but the pieces as a whole. Both the rootstock and the scion were growing by the time, they were soft. I just cut the top and the side of the rootstock, then I cut the scion diagonally and taped it tight to the side of the rootstock. I should have done some pics. In a few days started to push, those pics I posted were done 2 months after grafting. The rootstock developed the central pith or vascular cylinder. It can be seen in the photo close up as it has cracked the skin in the new joint area. This spring I'll do a few more and I'll try to take pictures of the process.

In Spain the best variety is Tanaka, big fruits, delicious. It produces around 15 days later than most of cv. I don't know if you have this one in USA though.

Since the topic came out in the main thread of DF, I update the post to show the success with the grafting of cv Queen on my old 1977 DF. I made kind of a veneer grafting, by placing the scion on the side of the rootstock instead of the top, this way was much easier to tape it. Two others that I tried in the top failed due to the very slippery surface and the difficulty to tape the scions. I used a very tiny piece as a scion, equivalent in size to a cut from the top of a seedling. Here a couple of pictures 2 months later.

Tropical Fruit Discussion / Re: KEITT Mango
« on: December 19, 2017, 12:45:37 PM »
I have a Keitt myself and since you are already talking about this variety I'd like to know how it works as intergrafting between the rootstock and a new cv. Does Keitt pass its growing habit to the cv grafted on it?

41
It could be just the wind. Here in Spain abandoned or ornamental chirimoya trees produce always some chirimoyas without hand pollination, and at least there is some bug that we are missing (which is not impossible) most likely is the wind or some kind of autopollination.

42
¿Tenéis anonáceas silvestres en vuestra zona? Teóricamente los insectos que polinizan de forma natural la chirimoya en los Andes deben tener parientes más o menos cercanos en el resto de Sudamérica.

It also got my attention that they don't even try to match cambium, but it must work, because there are several videos showing the method, like this one:

An another variant with younger stuff and using part of the stem along with the root:

Tropical Fruit Discussion / Multiroostock grafting into branches
« on: December 11, 2017, 01:17:19 PM »
I don't know if this grafting method have been already discussed in the forum, I couldn't find it. It's one of the weirdest ways to graft I've ever seen, instead of grafting cv into the rootstock, this method grafts several rootstocks into a cv branch, by using just their roots, like some kind of an air layering/grafting hybrid technique. By doing so, these guys get big plants with several main roots to feed the new tree.

Here in Spain best variety by far is Tanaka. Big fruit, sweet and complex flavor. As good as any other fruit in spring season, a must have in subtropics in my opinion.

These don’t like to be over watered when young. It might help to let them dry out every now and then.

Thank you! I'll keep that in mind too!

47
Reading your experiences it definitely seems that the problem is an excess of Nitrogen. Fortunately I have 4 other seeds in other pots (thank you Mike for that extra ;) ), I won't add any fertilizer until they are big enough, and then will be only Nutricote in very small dosis. Better to let them grow slowly that to kill them. These other seeds that are dying back had 2 heavy watering of rain water today, and will have more within the next days. I hope most of the citric fertilizer in the soil will be washed out and some survive.

48
There wasn't lack of humidity in the soil, and the air here in the coast is not dry either, so I think you are probably right about the second option. I gonna try to wash out the excess of nitrogen with rain water and  let's hope they recover, although being so small I'm not too much optimistic. Let's see... Thank you!!

Hi everyone,

I sown a few seeds of red jabo in September and finally two of them sprouted. Although didn't grow at all, they seemed OK until few days ago when I noticed that one had started to die back. Now the other one is dying back too. They are both still alive but it's plain that something is wrong in the conditions.They received some sun throw a window a few minutes per day (not anymore). Also I added by mistake water with some citric fertilise into the pot, in a normal dosis for mangoes. I wonder if any of these factors could explain this problem or could be something else. They are kept in a temperature of 64-74F. Any clue will be deeply appreciated.

I added the shipping fee for EU and Turkey. 6€ shipping for 25-30 seeds.
