Citizen science has been around for centuries, with lay people collecting data and making observations for scientists in a variety of fields. And, citizen scientists are contributing to discoveries as much in the 21st century as ever before.

P. ramorum spread to Northern Ireland
Tree killing disease spreads to NI
A private woodland and two government-owned forests in Northern Ireland have been devastated by an outbreak of a killer disease.
It has become known as Sudden Oak Death, but it is really a fungal-like infection that kills Japanese larch trees.

Research on SOD at Fort Detrick
Fort Detrick USDA unit a quiet but important part of global food security
On opposite ends of Fort Detrick, overshadowed by the mammoth infectious disease laboratories that sit in between, are two sets of greenhouses belonging to the U.S. Department of Agriculture.
The diseases studied inside aren't as infamous as the anthrax and Ebola tested elsewhere at Fort Detrick, but the USDA research in the greenhouses saves plants vital to the farming, lumber and tourism industries.

"Sudden Larch Death" in the UK
Plant pathology: Sudden larch death
Clive Brasier & Joan Webber
Nature 466:824–825
Date published:(12 August 2010)
doi:10.1038/466824a
An aggressive and unpredictable fungal pathogen is devastating larch plantations in Britain. Its remarkably broad host range, and the possibility of further geographical spread, give heightened cause for concern.

Adorn fungicide registered for use in California
Valent’s new chemistry provides control of key diseases, resistance management.
WALNUT CREEK, Calif. – Valent Professional Products announced that Adorn fungicide has been registered for use on ornamentals in California. Adorn is a new chemistry that controls downy mildew, Phytophthora and Pythium in greenhouse, nursery and outdoor landscape settings.
Available for use as a spray or drench, Adorn is effective against a number of diseases affecting California ornamentals, including sudden oak death (SOD) or Phytophthora ramorum. With a new mode of action, Adorn is also an excellent addition to fungicide rotations and plays a key role in resistance management programs when used as part of a tank mix.
Adorn has low-use rates of 1 to 2 ounces per 100 gallons as a drench and 2 to 4 ounces per 100 gallons as a spray. With its translaminar activity, Adorn provides enhanced plant coverage to help ensure growers and LCOs get more from their fungicide.

Swansea Bay rally halted after tree disease
The Swansea Bay Rally, postponed last month due to a tree disease, has been cancelled for 2010, say organisers.
The event, due to start and finish outside Swansea Museum on 17 July, was called off at short notice.
The route, near Resolven and Rhondda, went through areas that have been hit by the Phytophthora ramorum infection, also known as as "sudden oak death".
Rally organisers said the event could not be re-scheduled to take other qualifying rounds into account.
The rally, which has been running for almost 40 years, is part of the MSA National Gravel Rally Championship.
Around 80 semi-professional and club drivers were due to take part.

Nursery update for WA and OR
A King County, Washington retail nursery was found to have six
P. ramorum-positive rhododendrons in July. This nursery was also found positive for the pathogen in 2004, 2005, and 2006. CNP is underway. To date in 2010, the Washington State Department of Agriculture has processed more than 13,000 samples and detected P. ramorum at eight nurseries. For more information, contact Brad White at bwhite@agr.wa.gov.
A Washington County, Oregon retail nursery was found with two
P. ramorum-positive Rhododendron plants in mid-July. The nursery requested a survey after identifying a potential out-of-state customer. Prior to the confirmation, the nursery had not shipped interstate. This is the first time P. ramorum has been detected in this nursery. The USDA Retail CNP has been enacted.
As of 7/21, the Oregon Department of Agriculture has completed testing for the 2010 P. ramorum Federal Order Survey on 15,670 samples collected from 392 nursery grower locations. So far, P. ramorum has been detected in seven Oregon nurseries, with three nurseries having completed the CNP. For more information, contact Nancy Osterbauer at nosterba@oda.state.or.us.

SOD situation in Britain
Britain's Forestry Commission is continuing to try to minimize the spread of P. ramorum by felling tens of thousands of Japanese larch (Larix kaempferi), first found to be a sporulating host in southwest England in fall 2009. Since then, thousands of trees have died. Follow-up aerial surveys in southwest England and Wales, and up into western Scotland, have identified 203 suspicious sites in a mix of privately owned and Forestry Commission public woodlands in England and Wales. Of these, 42 sites in southwest England and eight in Wales have confirmed infestations. More than 30 hectares of trees were felled last winter, with an additional 250 hectares planned for removal this summer and fall. Felling is continuing in the southwest England counties of Devon and Cornwall, including Plym Woods, a popular forest for public recreation near the city of Plymouth, and is getting under way in Wales. The Forestry Commission hopes that by taking decisive action in southwest England and south Wales it can prevent the pathogen from spreading further into Britain.
Affected forests are remaining open to visitors, except for areas where felling is taking place, due to safety reasons. Visitors are being asked to stay on stone paths, keep dogs on short leads, and clean shoes and bikes before leaving infested areas. Private landowners are also being asked to regularly inspect woodlands where larch is present and to report any suspected P. ramorum outbreaks to the Forestry Commission. For more information, go to http://www.forestry.gov.uk/pramorum.
