Tropical Fruit Discussion / Re: Not enough Durian Discussion
« on: March 19, 2023, 10:37:47 PM »
I never thought of thatÖ
Iíve never heard of any problems but thatís interesting. We use a combination of chicken manure and cow manure mostly for top dressing fruit trees but I use the same mix in my potting medium. In the past Iíve blamed problems on incomplete composting of the chicken manure butÖ
Iím going to consider my sources. Many thanks.

Jay, thatís an interesting video. We have a somewhat similar approach. No NPK, Iím wondering about what the guy put that must have been like a bokashi.
Thatís a lot of cow manure which brings up a question. While recently traveling with Lindsay on the Malay peninsula there was talk about it being difficult to get cow manure. Then it struck me that driving around Latin America you see a lot of cattle pasture. You donít see pastures in Malaysia!  How about in Thailand, would it be easy to find cow manure in quantity?
Anyway, we ran into large planters who get the concept that the living soil is critical which is very positive and also what I got from the video.

I have been having some trouble posting images. But anyway you can see here what I am trying to do in shaping the young durian trees. Once you select a new leader and make your cut right above it then that branch starts to turn up and take over. At the same time the lower branches extend more.

Pretty good.
Did you say if that tree is a seedling or some grafted variety?

Tropical Fruit Discussion / Re: Bordeaux mix as Fungicide

Weíve used this Bordelaise mix very infrequently. Microorganisms have worked well for us in most cases for dealing with fungus.

Copper sulphate with calcium carbonate.
The ratios would depend but I donít think itís very critical.  Iíve used a very C rich mixt to make a paste for treating wounds on trees.  It can be used as a foliar spray.  If youíre interested in using whatís allowed within organics this classic combination is worth experimenting with.

Fresh durian will eventually be shipped to the US from Mexico and/or Central America. There are projects underway.

Your tree looks healthy. Iím not too sure if seedlings should be pruned the same as grafted trees. But what some would say is that looking at that tree you see an area near the top without many branches. Almost halfway down you get to an area where there is strong branching. You might select the top one of those branches to be the new leader by cutting off everything above it at an angle just above where that branch connects to the main stem.
I know that sounds radical and the tree doesnít look like it needs any drastic remedy. You could just leave it and keep doing what you are doing to promote lateral branches.
However, selecting a new leader should force the lower branches to spread wider.
Iíd be interested to hear what others suggest. Often, very competent pruners will have different approaches to working the same tree.

The harvest is predicted based on when the flowers drop.
How you might cull flowers or fruits can depend on what sort of harvest you want. Do you want a long slow harvest or do you want to concentrate the harvest. Depends on your market and if you want to be eating durians for as long as possible.
Nice job Cainito. Felicidades

I wonder about that too. I have been waiting for a seedling to flower for more than ten years. Do you have mulchi in production?  So far only the dwarf mulchi has produced here.

Hi
I think I made a mistake, they are cherapu. 😉

To me, that doesnít look like cherapu.  The leaves should be smoother, more mangosteen like, not with any wrinkles.

I agree with that.
Here you can see a few opened kampung durians in Pahang. Many times Iíve seen Lindsay sort through piles of low priced durians and extract something very tasty.
At the stand you see black thorn at $US12kg and Kampung $1.50kg!

Ultimately it has to be whatís best for the consumer. I am the president of our farmers market and there is a tendency of some to favor the vendors but we need, above all, consumer satisfaction. In Australia if your customers are happy it doesnít matter whatís happening in Thailand.
The photo is of prices at a stand in Penang last month. You can see that there are different qualities of Bkack thorn and musang king. There are at least 3 grades or qualities determined for the same durian varieties. Incidentally, these prices are about double what I saw in the production zones.

Yeah, there are a few trade offs. Penang gets about 2500mm a year but since it has distinct dry and wet seasons they only get one harvest whereas if you have two short dry seasons you can get two fruit seasons like in Pahang where I was a month ago. Parts of Pahang get higher rainfall.
Itís commonly believed that Black Thorn doesnít do well in the conditions of Pahang but is great for Penang. In Pahang they are quite pleased with Musang King so it seems that you need to match the variety with the location.
There could be lots of factors involved besides rainfall patterns to get the most successful match. Itís tricky. I think that this is where planting seedlings comes in. Ideally we will find new varieties especially suited to our conditions. More Malaysians are now mounding in rainy areas and getting good results.
Still, we are planting Malaysian selections since the quality is so good. Itís a learning process, mostly lots of fun but tempered with some disappointment as we advance along.

This is a very interesting subject.
First off it seems that Thai varieties grown in Malaysia can be different from those in Thailand.
Mongthong can have problems of uneven ripening in Thailand.
All this according to Lindsay.
We are barely getting started here. The D-99 we grow can be terrific, but not always. Fruits from the same tree can vary. We have had very good Chanee off a young tree here. There is mongthong and musang king in production in CR but only within the last 3-5 years!
One of these areas is marginally suitable with very dry winds. Another has its harvest during the rainy season which doesnít help quality. In Costa Rica most durian planting occurs on the Caribbean coast where we are or near the Pacific coast in the southern section. The country is small but the climate varies considerably from one region to another.
There are some good seedlings and we are working hard on seedlings to develop our own varieties. But nobody is pulling out Asian selections. Lots of seedlings were distributed by an NGO in the 80ís.  Only a few of those would be worth grafting.  Most tree buyers desire the Asian varieties so far.

We are having durian right now as well, D-99. This is earlier than normal but, welcome of course!

I think itís propagated by cuttings. If that isnít working then I would use a ground layer.

Cassowary, that systemic pesticides are widely used in Thailand doesnít surprise me but itís not what I found in Malaysia. What systemic pesticides are you referring to?
On major farms I saw the use of EM and biological control products like baccilus thurgensis. I donít think those are compatible with conventional pesticides.
Some places you see herbicides and theyíre probably using nematacides as well. But I listened to farmers trash talking herbicides and talking about the necessity of living soil with lots of worms. Control of erosion is also a concern.

Nice, I think Ganyao has a much better reputation than mongthong. I have a grafted tree that is from a seedling of Ganyao. The seedling came very good so I imagine yours will as well.

Hi Carolyn
I have been to a farm here that grows and sells laroco. Itís not a heavy vine like passiflora or something. Your plan should work well.

Jay, thatís a strange video. Yes, I hear the guy say systemic fungicide but the application is more like a contact treatment of an obvious infestation.
What concerns me more would be a program systemic application which would be directed at the foliage and the fruit would always, in that case, loaded with fungicide.

Tropo I feel for youÖ
Funny thing is that when itís dry in Oz and fires are the problem itís raining like crazy in my neck of the woods. The last year has been very dry here. Not that good for planting but great for fruit production. Weíre eating durian now!

We can get that much rain. Penang gets less but some parts of Malaysia get that and have good production. The videos that Jay and I have been talking about show the durians planted on steep mounds if they are on the flat. The guy also sometimes makes ditches for drainage. We are planting on hills now but have good trees where the ground gets pretty wet and water can stand in depressions. I cringe when I see that but, weíre still in business.
