[nafex] black lace elderberry
Im working with a client to upgrade and expand edibles on their property.
They have a black lace elderberry, from a previous landscaper. I saw in the
past nafex messages it was mentioned as a european variety, but no mention
of whether it fruits as well as some of the other, less-ornamental
varieties. Anyone have any experience with this variety and can speak to
whether its worth the space it takes up? (Im wondering about fruit
production-- Ill move it elsewhere if its mostly just a pretty bush)
thanks in advance

Re: [nafex] goumi and mold
Shelly, I grow 2 varieties in your area. I do not have problems with mold. I have them about 6 feet apart and they are at least 7 feet high. They have sun from mid morning through sunset. They have moderate air flow only. Contact me off list if you wish to discussBetsy Hilborn Sent via the Samsung Galaxy Note® 3, an AT&T 4G LTE smartphone

Subject: [nafex] goumi and mold
Hello NAFEXers,Has anyone encountered difficulty with mold on goumi? I am in the southeast where humidity presents a real challenge for fruit growing.I have found that goumi are quite astringent until ripe (when they can easily be pulled from their stems) but that by the time they are ripe, a black mold begins to appear on the surface and quickly spreads between fruit. For the two years the plants have been fruiting, I have lost the majority of the crop to the mold. This year, I covered the plants with a low-tunnel (with the sides open) to keep the plants dry. Even this did not seem to reduce the mold spread. I could probably be more cognizant of only harvesting when the dew has dried. I am not certain if goumi will continue ripening off the plant. Does anyone have experience with this? Any suggestions or recommendations?I love the taste of goumi and they are popular with my market customers. They seem worthwhile if I can figure out a solution to the mold. Thank you,Shelley Orby Dare OrchardCedar Grove, NC__________________nafex mailing listnafex@lists.ibiblio.orgNorthamerican Allied Fruit Experimenterssubscribe/unsubscribe|user config|list info:https://lists.ibiblio.org/mailman/listinfo/nafex

Re: [nafex] jujube in "cold" climates
Well that is encouraging. I am in Payette Idaho, Zone 6 Oregon border. Not that much wind. But my front flower bed has extra heat reflected down on it from the wall of the house that faces west. As a result I have a faithfully bearing apricot tree. And raspberries, and currants.

I'm in zone 5 (northern Utah/Idaho border, 4,900' elevation, 18" annual precip) and grow Li and Lang, now nearly 10 yrs old. They are planted on a south-facing slope, slightly warmer microclimate, very hot/dry summer location, high winter wind area. I get good crops and have not experienced winter injury. I watered them first 2 yrs to get them established, but they have no supplemental irrigation at this point, though are in a bed with deep mulch (permaculture system) and companion plantings w/sea buckthorn (N-fixer). Lang is 8' tall, Li stopped at 4'.

Yes, short seasons are the issue.
I am in zone 7 and had a short list of varieties that would bear early enough in the season. I grow So, Sherwood and Shanxi Li.
They bloom late, so late frosts are not an issue.

Hmm. Maybe I should give jujube a try. Our season didn't use to be reliably that long; but now most of the time it's longer. I'm not sure I've ever seen -17 F here; and even negative low teens has become quite uncommon.
— and I'd like to say that it's nice to see this list resurface in my mailbox!

many July days is lower 90s.
I don't if this qualifies as "short season" but our Jujubes fruit every
year, without miss. Been getting fruit 17 yrs now.

Great year for Li and Lang jujubes. Also trifoliate orange.

Jujubes-- if the right variety is selected they can do well in cooler more coastal conditions - I have grown Li which does not need as much heat as the others.

Yes, short seasons are the issue.
I am in zone 7 and had a short list of varieties that would bear early enough in the season. I grow So, Sherwood and Shanxi Li.
They bloom late, so late frosts are not an issue.

Re: [nafex] Northern Blackberries
I have tried all blackberries that I could find offered for sale
from catalogs and while a few were both hardy and productive, all were
very susceptible to fungi. One variety, Thibodaux was worthy but
needed to be buried under the snow to thrive.
from catalogs and while a few were both hardy and productive, all were

SO, I developed my own to be super hardy, quite productive, disease
resistant, and even grows in the filtered sunlight among pine trees.

Subject: Northern Blackberries
Hello. My name Is James Snow. I see you are the NAFEX interest group
leader for Rubus for the north. I have been interested in growing
blackberries in Kansas. The few kinds I have grown seem to have lots
of winter kill. I am currently looking at gathering hardy blackberry
varieties for trial and possible breeding here. Kansas is challenging
as it gets both very hot in summer and very cold in winter. It seems
many of the very hardy blackberry varieties are hard to locate. I have
tried to find "Illini Hardy" with no success. Do you have any
experience with "Nelson" or "Stenulson". Any recomondations?
Also do you have any experience with wild "Rubus Canadensis" the
Canada Smooth Blackberry, Thornless? Thanks
-James

Re: [nafex] Sweet European fruit
Andy Mariani grows some Mirabelle in CA. I don't think he ships them fresh,
though, and they don't seem to dry well.

If you're interested in trees, Arboreum sells some.

Are they available in N America, perhaps under different names?

There is a large pear tree in the
former pasture behind the farm in
Dakota County, Minnesota.
Its trunk is about 40 inches in
diameter. It towers above the other
trees around it.
The beautiful display of white flowers
got my attention this spring.
The fruit are a couple inches long,
pear shaped and green when they
fall from the tree. Hard but tasty.
It does not match callery pear nor
Ussurian pear.
Any way to figure what kind of pear we
have?

Henry, it is unlikely you will find an answer with a simple description
like this, although the location of the pear may be your best lead- if
there is any information of what varieties were grown in your region over a
century ago (you could ask the librarian of the land grant university in
your state if there is any literature on the subject). In the end, the
chances are good that it is a seedling, in which case it is whatever you
want to call it.

[nafex] pear question
There is a large pear tree in the former pasture behind the farm in Dakota County, Minnesota.
Its trunk is about 40 inches in diameter. It towers above the other trees around it.
The beautiful display of white flowers got my attention this spring.
The fruit are a couple inches long, pear shaped and green when they fall from the tree. Hard but tasty.
It does not match callery pear nor Ussurian pear.
Any way to figure what kind of pear we have?

[nafex] Fwd: PAECILOMYCES ROT, APPLE
FYI from ProMed mail
PAECILOMYCES ROT, APPLE - USA: (NEW YORK), NEW DISEASE
******************************************************

A mold found in more than a 3rd of the soil samples from New York State apple orchards is causing a new disease, spoiling apples, even after heat pasteurization. The state is the top producer of processed apple products and they all rely on pasteurization.
Cornell's Kathie Hodge and Megan Biango-Daniels investigated the origins of a newly discovered apple disease called Paecilomyces Rot, caused by the common fungus found in 34 per cent of state orchards.
Previously, scientists believed the fungus was coming from soil contamination, but Hodge and Biango-Daniels believe other infected apples are the primary source.
Since this new apple disease appears similar in appearance to others, the scientists suggest apple producers isolate any of the fruit with wounds or bruising in order to avoid the spread of Paecilomyces Rot.

[The fungus causing this new disease has been identified as _Byssochlamys lagunculariae_ (previously _Paecilomyces niveus_; see source link below). The external fruit rot develops mainly in storage after harvest and symptoms appear to be similar to fruit rots due to other fungi. Susceptibility may vary somewhat between apple cultivars.
The fungus survives in orchard soils and on decaying plant material.
The significance of this report is stated as (1) the production of a mycotoxin, and (2) the fungus remaining infectious after commercial pasteurisation. Spores are reported to be tolerant of temperatures of up to 90 degrees Celsius [194 F] and are suspected to be the cause of spoilage of canned products, leading to severe economic losses for the affected apple producers. This pathogen also appears to facilitate secondary infections by other fungi.
Other species in the genus _Byssochlamys_ are also known to produce mycotoxins and form heat resistant ascospores. They have been reported from soils in many areas and can cause problems, for example, in grapevine and tomato products.

[nafex] Prairie series american persimmons
Checking to see if anyone has any experience with the 'prairie' series of
american persimmons? Prairie dawn, prairie star, prairie sun...
(trademarked). Didnt see any notes when I searched back messages. Im really
liking how easy american persimmons are to grow- very reliable bearing and
little pest issues. Looking for good varieties and I saw these in the one
green world catalog.

Re: [nafex] International Fruit & Nut Enthusiasts & Breeders
That's always been the case with this list. There was a long time when if you googled my name, you found the list archives (with my email info). It seems less problematic now than in the past, since spam is a less serious problem than it used to be.

CHERRY VIRUSES - USA: SPREAD

<http://www.washingtonagnetwork.com/2017/12/28/cherry-viruses-moving-washington-oregon/>
Researchers at Oregon State University [OSU] have discovered that many of the viruses that have plagued the cherry growers in Washington [see ProMED-mail post http://promedmail.org/post/20140127.2233739] have moved to Oregon: viruses like cherry leaf roll virus, tomato ringspot, tobacco ringspot and little cherry disease.
OSU's Jay Pscheidt said it's important for growers to not ignore problems, look for symptoms and work with labs that can test for these diseases. "Our next step is to find out how prevalent they are."
Removal of viruses that you don't know are there is obviously quite difficult.

<promed@promedmail.org>
[Around 30 viruses have been found to affect sweet (_Prunus avium_) and/or sour (_P. cerasus_) cherry trees, singly or in coinfections.
Many of them also affect other _Prunus_ species.
Of the viruses mentioned above, _Cherry leafroll virus (CLRV), _Tomato ringspot virus_ (ToRSV) and _Tobacco ringspot virus_ (TRSV) all belong to genus _Nepovirus_. On cherry, CLRV and TRSV mainly cause leaf symptoms as indicated by their names, ToRSV has also been associated with stem pitting. Generally, members of the genus are transmitted by nematodes, but most can also be transmitted by mechanical means, with infected planting and grafting material and to varying degrees by seed and pollen.
Little cherry disease (LCD) is a serious problem for sweet and sour cherry producers in parts of northern Europe and North America. It can be caused by 2 closteroviruses, _Little cherry virus 1_ (LChV-1, not yet assigned to a genus) and LChV-2 (genus _Ampelovirus_), in single or mixed infections. Symptoms vary with host cultivars, but may include reduced size and quality of fruit, premature leaf reddening, stunting of seedlings and some loss of tree vigour. All commercial cherry cultivars are susceptible, and ornamental flowering cherries can be asymptomatic reservoirs of LChV-1. LChV-2 is transmitted by mealybug vectors which can be spread by wind and with packing material. An insect vector for LChV-1 is not known. Both viruses can be spread by both shoot and root grafting and with infected plant material.
Disease management for fruit tree viruses may include phytosanitation in orchards, use of certified clean planting stock and budwood, elimination of inoculum (removal of infected trees) and vector control if feasible.

Researchers at Oregon State University [OSU] have discovered that many of the viruses that have plagued the cherry growers in Washington [see ProMED-mail post http://promedmail.org/post/20140127.2233739] have moved to Oregon: viruses like cherry leaf roll virus, tomato ringspot, tobacco ringspot and little cherry disease.
OSU's Jay Pscheidt said it's important for growers to not ignore problems, look for symptoms and work with labs that can test for these diseases. "Our next step is to find out how prevalent they are."
Removal of viruses that you don't know are there is obviously quite difficult.

[Around 30 viruses have been found to affect sweet (_Prunus avium_) and/or sour (_P. cerasus_) cherry trees, singly or in coinfections.
Many of them also affect other _Prunus_ species.
Of the viruses mentioned above, _Cherry leafroll virus (CLRV), _Tomato ringspot virus_ (ToRSV) and _Tobacco ringspot virus_ (TRSV) all belong to genus _Nepovirus_. On cherry, CLRV and TRSV mainly cause leaf symptoms as indicated by their names, ToRSV has also been associated with stem pitting. Generally, members of the genus are transmitted by nematodes, but most can also be transmitted by mechanical means, with infected planting and grafting material and to varying degrees by seed and pollen.
Little cherry disease (LCD) is a serious problem for sweet and sour cherry producers in parts of northern Europe and North America. It can be caused by 2 closteroviruses, _Little cherry virus 1_ (LChV-1, not yet assigned to a genus) and LChV-2 (genus _Ampelovirus_), in single or mixed infections. Symptoms vary with host cultivars, but may include reduced size and quality of fruit, premature leaf reddening, stunting of seedlings and some loss of tree vigour. All commercial cherry cultivars are susceptible, and ornamental flowering cherries can be asymptomatic reservoirs of LChV-1. LChV-2 is transmitted by mealybug vectors which can be spread by wind and with packing material. An insect vector for LChV-1 is not known. Both viruses can be spread by both shoot and root grafting and with infected plant material.
Disease management for fruit tree viruses may include phytosanitation in orchards, use of certified clean planting stock and budwood, elimination of inoculum (removal of infected trees) and vector control if feasible.

In the Northeast [of the US], Canada and North Carolina, young dwarf trees in high-density orchards are dying [see ProMED-mail post http://promedmail.org/post/20100608.1911] with increased frequency.
The Pennsylvania Department of Agriculture, Cornell University, University of North Carolina and others have teamed up to solve the mystery of Rapid (or Sudden) Apple Decline (RAD or SAD).
There seems to be some connection to M9 rootstock, although other rootstocks also can be impacted. Fuji, Gala and Golden Delicious cultivars appear most susceptible. This might indicate some cultivar-rootstock combination triggering RAD. Observations do not point to any specific pathogen, abiotic factors may play a role, [but] there is no obvious common denominator among the impacted trees.
Trees, even those full of fruit, quickly die from RAD. The graft union shows necrosis [which] continues up the bark. Severe bark shedding near the graft union [and] cankers are also seen. Within 2 to 3 weeks, leaves turn yellow and the tree dies. There are few signals that anything is wrong prior to the sudden emergence of symptoms. Trees collapse completely, despite the wood being solid and the roots healthy. In any given block, trees with RAD are scattered with no pattern, [and] some trees can remain healthy.
Because stress is believed to be a factor in RAD, growers are advised to eliminate as many stressors as possible. Alternative rootstocks to
M9 could afford protection. Other [factors] may be playing some role in the syndrome and viruses or [other] pathogens - known or as yet unidentified - may also be contributing.

[This undiagnosed disease or disorder in apple orchards was previously reported from Michigan and New York (ProMED-mail post http://promedmail.org/post/20100608.1911). It now appears to be much more widely distributed but unfortunately not much progress seems to have been made in the search for a cause.
Association with specific dwarfing rootstocks and apple varieties may imply graft transmissible agents such as viruses, viroids or phytoplasmas. Molecular methods are needed for their detection, but no information is provided in the report above whether a systematic molecular search for any pathogens has already been undertaken. As mentioned above, SAD may also represent a syndrome including a number of different factors, which would make the task of identifying a cause much more complex.
Generally, to identify a biotic or abiotic cause for a disease or disorder of unknown aetiology, a defined process must be followed:
description of specific symptoms in individual plants; patterns of their distribution in space and time; evidence for or against transmission of symptoms and spread of the condition; Koch's rules (i.e. to re-isolate an infectious pathogen after culture and transmission, or equivalent process for non-culturable pathogens) to test for causation by a biotic agent; molecular studies to identify a known or characterise a novel potential infectious agent. Especially in slow growing hosts, such as trees, this process may take many years and it would be complicated considerably if a previously unknown pathogen were to be involved.
