Hi Henry,

It was a very good meeting. There are plans on developing more promotional materials that can be distributed via the website and other outlets that would highlight the goals of NCPN-R and the resources in place and on the horizon. There are advances being made in diagnostic techniques, especially for some of the newer viruses, that can be uniform and adopted by plant disease clinics far and wide. There are efforts to continue to clean up more rose varieties, continue to develop and expand the new clean plant block at FPS, and encourage more rose producers and breeders to participate.

There were a lot of great discussions with all the key stakeholders represented (scientists studying topics that relate to the mission, USDA NCPN representatives, breeders, propagators, landscapers, public garden reps, etc.). There is not a proceedings with abstracts or written papers. The presentations were well done with good background information and updates on ongoing research. A goal throughout was to stimulate discussion for where to focus our efforts with the limited resources.

Please look to the website for updates as time goes by. You can also look at the Foundation Plant Services website for additional roses being added to the collection as they pass the tests and are included in the clean stock block and become available.

It is a very valuable program that will especially help maintain and expand the clean stock block at UC-Davis, expand what is tested for to be up to date with more newly identified problematic viruses in particular, and encourage and help industry to take advantage of this valuable resource to help keep the rose industry viable.

Thank you Dave. Needless to say, I am disappointed to hear that not even the abstracts will be available.

This publication appears to overlap and/or supplement some of what the Clean Plant group are doing (but with other plants):

Does anyone know if the Power Points have been posted yet? And, if so, what is/are the link(s) to view them?
Thank you.

This is the latest general information about the program that I could find:

If you did not sign up to receive information from NCPN about rose viruses, they just posted a rose rosette virus brief summary.

New (2018) general article about rose viruses from National Clean Plant Network.
See:
http://nationalcleanplantnetwork.org/files/276825.pdf
The main difference between it and earlier articles (to me) is that it states: " Several viruses are found worldwide, including Prunus necrotic ringspot virus (PNRSV), Apple Mosaic Virus (ApMV), and Rose spring dwarf-associated virus (RSDaV."
H.Kuska comment: Please notice that Rose spring dwarf is now stated as found worldwide. This is an aphid spread virus and is not cleaned by heat treatment.

Well, it appears that of this date (3-22-2018) the Power Points from the National Roses Clean Plant Meeting have not been posted yet.

This is what has appeared from a Columbia-rose-virus-certification-program

The federal funding for 2018 National Clean Plant Program has been announced.
"Farm Bill Section 10007(e) FY18 Spending Plan National Clean Plant Network March 22, 2018"

https://www.aphis.usda.gov/plant_health ... g-Plan.pdf

The Univ. California, Davis gets $1,123,116 for the study of Grapes, Fruit Trees, Roses, and Sweet Potatos. I did not find a breakdown as to how much goes to roses.

I did find a brief summary: "The purpose of the NCPN is to protect plants of economic value by diagnosing for plant pathogens, curing those plants, and to protect starter plants and make them available to industry.  
Cumulative highlights since 2014 include: "Roses – Currently doing advanced diagnostic testing on about 600 kinds of roses that are used as starters, with a goal of trippling the starter material available to industry"

https://www.aphis.usda.gov/aphis/ourfoc ... on/sa_ncpn

The Univ. of Maryland gets $102,938 for its Roses Nat’l Germplasm Resources Lab.

The Texas A&M Univ gets $230,953 for its Texas Roses Clean Plant Center.

This is wonderful news!!!

The U of Maryland money, from my understanding, is to help house a virus positive collection and generate a source for material positive for various rose viruses for plant diagnostics labs to have as positive controls to make sure PCR and/or ELISA tests are effectively detecting the viruses in question.

Regarding the Aug 5, 2017 post that stated:
"We just got an email that the PowerPoints of those that presented will be posted on the website with the speakers permission."

As of yesterday they have not appeared. I enquired about the talk that was titled: "Managing Reinfection of Clean Stock" . I did receive a copy; however the actual title is: "Managing Infection of Rose Rosette Virus in Clean Stock ".

I also asked when the next meeting is scheduled. I was told that it will be on June 26-27, 2018, LA County Arboretum, Arcadia, CA .

I did not get a copy of the program (topics nor speakers).

I received a copy of the minutes of the 2017 meeting. It came by e-mail so I cannot link to it.
I assume that the minutes will have to be approved at this coming 2018 meeting so I probably should not quote from it at this point.

I just obtained a copy of a University of Utah Extension web page (2017 copyright) that attributes the spread of Rose Mosaic Virus (Prunus necrotic ring spot virus; Apple mosaic virus) in roses to aphids. Unfortunately no documentation was provided.

https://utahpests.usu.edu/ipm/ornamenta ... ose-mosaic

I tried looking for other references supporting the aphid statement and came across the following:
"Shown here is rose mosaic virus. This is likely to be spread by aphids (image courtesy of The Utah Department of Agriculture and Food, Division of Plant Industry)."

http://www.sgaonline.org.au/virus-or-variegation/

I hope that this idea of aphid spread is discussed at the meeting.

This is from a 2018 copyright University of Illinois extension article regarding rose mosaic virus:

"Try to control insects, especially aphids, since they help spread the virus. "

H.Kuska comment: since the National Clean Plant program is federally funded, I would expect that the contents of Bedard's talk would be made available to the public.
