Dear colleague,
herewith I like to inform you about the upcoming IUFRO Pine Wilt Disease unit symposium which will be held in Braunschweig/Germany from 15th to 18th October 2013.
The symposium PWD 2013 is a joint action of the International Union of Forest Research Organizations (IUFRO) unit 7.02.10 Pine Wilt Disease (PWD) and the group of the EU-research project REPHRAME "Development of improved methods for detection, control and eradication of pine wood nematode" in cooperation with The German Scientific Society for Plant Protection and Plant Health and the Julius Kühn-Institut, Federal Research centre for cultivated plants.
Since the last IUFRO Symposium in Nanjing/China in 2009, several expert groups in the whole world - among other things - worked intensively on the following topics:
· Impact on the international trade as well as economic consequences in the infested areas including corresponding modeling of outbreak scenarios and pathways,
· Pathway analysis and modeling/predicting of pine wilt expression across eco-climatic zones taking account of latency ,
· Biology of Bursaphelenchus xylophilus and other Bursaphelenchus species including their interaction with bacteria and fungi and their impact on host trees,
· Diagnostic methods aimed to a fast and reliable determination of PWN in pure culture and in plant tissue as well as in laboratory and under field conditions,
· Examinations on the tree physiology and resistance characteristics of host trees,
· PWN and vector association, vector dispersal capacity and strategies for vector control,
· Behavior and population dynamics in infested trees,
· Non-vector transmission and treatment options for wood and wood products,
· Management strategies for PWD.
The aim of the symposium is to bundle the actual research progress and the management of the pine wood nematode and its vector beetles and to enhance the scientific exchange and thus to present the research results to a broad interested group of scientists, disease managers and decision makers. You are invited to submit papers for oral presentations as well as for posters covering all aspects around Pine Wood Nematode and Pine Wilt Disease.
All information including registration is available at: http://dpg.phytomedizin.org/de/pwdc2013/.
The deadline for abstract submission is 30. June 2013. Early bird fee payment is until 31 July 2013.
The organization committee would be grateful if you could share this email with people you think could be interested to participate. Thank you!
I hope to see you in Braunschweig!
With best regards
for the local organizing board

This year, the Northeast Forest Health Workshop is being held jointly with
the spring meeting for the New England Society of American Foresters on
Wednesday through Friday, May 15-17, at the Sunday River Resort near
Bethel, Maine . The full conference is entitled, "What's in Your Woods?"
The program will start with a joint session from 1 pm to 3 pm, and then
we’ll have our own indoor session from 3:30 to 5 pm. People who have agreed
to give talks at this time include Nicholas Brazee (wood-inhabiting fungi),
Don Davis (fungal biocontrol of tree-of-heaven), Dale Bergdahl (butternut
health), Shawn Kenaley (fungal pathogens of hardwood plantations), and a
group presentation on ash health and the Emerald Ash Borer. After dinner
on our own, we can return for station reports from 7 to 9 pm.
On Thursday, an all-day field trip is planned. In the morning, Isabel Munck
(USFS, Durham) and William Ostrofsky (Maine Forest Service) will host a
tour of white pine needle damage/defoliation and Sirococcus shoot blight of
eastern hemlock and red pine.
In the afternoon, Bill Livingston (UMaine), Kara Lorion (UMaine), Colleen
Teerling (Maine Forest Service), and Nate Siegert (USFS, Durham) will host
a tour involving ash dieback/decline and monitoring for the emerald ash
borer, including hands-on demonstrations for girdling EAB trap trees.
We are also talking with the Maine Indian Basketmakers Alliance to have
representatives attend the meeting, and they would discuss the use of ash
from their perspective and the need to conserve healthy brown ash (=black
ash) with basket-quality wood.
Thursday evening will have a bar-b-q that's included in the registration
cost.
Friday morning will include another field trip. We'll travel on our own
from Sunday River Resort to Wolfe's Neck State Park on the coast near
Freeport, Maine. Alison Kanoti (Maine Forest Service) has arranged a tour
in the region to view a winter moth infestation, a browntail moth
infestation site where a BTM virus has been released, and a hemlock woolly
adelgid infestation where predatory beetles have been released. The tour
will end around noon after which LL Bean and factory outlets await you.
Early-bird registration cost is $99 including field trip transportation and
all meals on Thursday and breakfast & box lunch on Friday. After March 15,
registration increases to $120. Student registration is $70. Registration
rates go up after April 15.
Hotel rooms will be $79 per night at a nearby inn or $94 per night at the
Summit Resort which has the meeting rooms. To make reservations contact the
Reservation Department directly: (800) 207-2365. Please request the NESAF
room rate for the "NESAF 93 Annual Meeting 2013"
The group rates are available until April 15, 2013.
More program information is on NESAF web site: http://nesaf.org/
Registration is done on line at:
http://events.constantcontact.com/register/event?llr=ubvoh9lab&oeidk=a07e6x…
Be sure to select Tour 6 and Friday Tour 3.
Let me know if you have any questions, and I hope to see you in May!

Dear colleagues and friends,
We would like to inform you about the upcoming “5th Phytophthora, Pythium and related genera workshop” that will take place in Beijing, China on 24-25 August 2013, immediately prior to the International Congress of Plant Pathology (ICPP; 25-30 August, 2013).
This is a two-day pre-congress workshop that will provide an additional platform to bring together scientists working on Oomycetes. The objective of the first day is to introduce the methodology for studying Oomycetes, in particular, Phytophthora and Pythium species (from isolation to characterization using morphological and molecular tools). The second day will cover contemporary research topics presented by invited and contributed speakers (see webpage for range of topics). During the evening there will be a poster session where all participants can present their work (these posters can be the same that will be presented during the ICPP)
Abstract Submission: Workshop deadline (to be considered for oral presentation) is April 1st 2013 and for the ICPP 28 February 2013.
For abstract submission, registration and detailed information on the workshop, please visit the congress website: http://www.icppbj2013.org/file/workshop/5thInternationalWorkshop.asp
If you are interested in contributing to the sessions (oral papers and posters), please inform the session organizers while submitting your abstracts online using the ICPP web page. Final selections for oral presentations will be made after registration has been completed.
Sessions for the second day are:
Session 1 Genomics and Oomycetes. Opportunities in comparative genomics.
Session 2 Taxonomy and Phylogeny of Oomycetes
Session 3: Emerging diseases, new technologies and management of Oomycete diseases in agricultural and natural settings
Session 4 Population biology, gene flow and hybridization.
The members of scientific committee are Drs. Yilmaz Balci (ybalci(a)umd.edu<mailto:ybalci@umd.edu>); David Cooke (david.cooke(a)hutton.ac.uk); Frank Martin (Frank.Martin(a)ARS.USDA.GOV) and Zhao Wenxia (zhaowenxia(a)caf.ac.cn<mailto:zhaowenxia@caf.ac.cn>) for all local arrangements.

Many years ago I saw similar sphaeroblasts of ¼ to ½ inch diameter that developed within resin pockets of the bark on balsam fir in northern Minnesota with very similar appearance to the beech bumps. Some were perfectly egg-shaped and free from attachment to the xylem, others had vascular connections. All had beautifully swirled grain.

Subject: Re: [IUFRO RG 7.02 FORPATH] FW: Bumps on Beech
Dear Enrico,
I often see similar bumps on European beech and have identified them as sphaeroblasts, which are thought to develop from dormant buds. In place of a shoot, a ball of wood develops, encased in bark. A sphaeroblast can be easily detached with a mallet etc., since its woody connection to the stem is very narrow. The large sphaeroblast in the attached picture shows an arrow pointing towards the woody connection on the proximal side. Some of the bark has been pared away with a knife to expose this connection. The picture also shows wood exposed on the proximal side (with partial occlusion), perhaps because of an old injury or as a result of bark dieback. Similar canker-like areas can be seen on the bumps in John McLaughlin's photos but I doubt whether these bumps are sphaeroblasts, since their close alignment is unlikely to correspond with the positions of dormant buds.
Small bumps on American beech can also be induced by the scale insect Xylococculus betulae, which penetrates as far as the cambial zone (especially in the aftermath zones of beech bark disease [see Dave Houston's article in J. For., 73(10), 1975]. I think that they usually look rougher and corkier than the bumps in John's photos but my experience of this insect has been limited to looking at photos and to two brief visits to the USA.
Kind regards,
David

While I was at Harvard I found this beech tree with some interesting wart-like mounds on its bark. Is this normal for some beeches, or could it potentially be a paper topic? Do you know what it is?

My thanks to Guy Bussières at Université Laval, in Québec City for directing me to a 2012 paper by Colin et al. (Annals of Botany 110: 995-1005) which describes these bumps as a form of epicormic growth they called spheroblasts, "Isolated buds progressively engulfed in a small ball of wood generated from the base of the bud on the external side".
