Thank you very much for coming. I know that many of you have traveled from quite a distance and I'd like to acknowledge participants from Australia, Belgium, Bhutan, Canada, France, Germany, India, Ireland, Iran, Iraq, Italy, Libya, Nepal, Netherland, Pakistan, Serbia, South Africa, Spain, Czech Republic, Sweden, Switzerland, United Kingdom, and United State of America who have made this long trip. The diverse forest types and plant species of Viet Nam provide much needed resources for over 25 million people. Unfortunately, this need has led to unsustainable forestry practices including a long history of deforestation. Economic development, climate change, and pest and disease factors as well have already impacted diversity of Viet Nam’s forests, and the problem has great potential to increase over time. We hope very much that this meeting can bring to us valuable scientific information on Phytophthora and the role it plays in natural ecosystems, especially pathways to and from other land uses such as agricultural, forestry and the urban environment. Such information is crucial for proper policy development on protection and development at the national scale of our natural forests and forest plantation. To all of you, thank you for being here, welcome, and enjoy the conference!

Abstract Common alder (Alnus glutinosa) is an important tree species, especially in riparian and wet habitats. Alder is very common across Ireland and Northern Ireland, and provides a wide range of ecosystem services. Surveys along the river Lagan in Belfast, Northern Ireland led to the detection of several diseased Alnus trees. As it is known that Alnus suffers from a Phytophthora induced decline, this research set out to identify the presence and scale of the risk to Alnus health from Phytophthora and other closely related oomycetes. Sampling and a combination of morphological and molecular testing of symptomatic plant material and river baits identified the presence of several Phytophthora species, including Phytophthora lacustris. A survey of the tree vegetation along an 8.5 km stretch of the river revealed that of the 166 Alnus trees counted, 28 were severely defoliated/diseased and 9 were dead.

    Steps towards integrated management of Forest Research Phytophthora kernoviae and P. ramorum on magnolias in British heritage gardens Sandra Denman, Susan Kirk and Alistair Whybrow Forest Research, Alice Holt Lodge, Farnham, Surrey GU10 4LH, UK. Introduction Phytophthora kernoviae (Pk) and P. ramorum (Pr) are newly invasive Phytophthora species in Britain causing disfigurement and death of ornamental plants and trees in nurseries, native woodlands and gardens (Figures 1 and 2). Many of the gardens have heritage value and house collections of rare and exotic plants (e.g. the ‘National Magnolia Collection’). These serve as an important genetic resource but the gardens are also a significant source of tourist revenue. Some of the plant species that form the essential character of the gardens are primary foliar hosts for Pr and Pk and produce Figure 1. Shoot tip dieback and Figure 2.

  • Phytophthora Kernoviae
    pk updated may 2010 v2:Layout 1 11/05/2010 10:26 Page 1 A threat to our woodlands, heathlands and historic gardens Phytophthora kernoviae Canker on the trunk of a mature beech tree, next to an infected rhododendron. Photo courtesy of Forest Research What is it and where is it found? Phytophthora kernoviae is a serious plant pathogen causing diseases of trees and shrubs in UK woodlands, heathlands and managed gardens. The pathogen was first discovered in October 2003 in historic woodland gardens in the heart of Cornwall, where both large rhododendron bushes and beech trees appeared to be dying from an unknown cause. Further investigations by Fera and Forest Research revealed a previously undescribed fungus-like organism. It has now been named Phytophthora kernoviae (derived from Kernow, an old Cornish name for Cornwall). Since it was first detected, there have been findings in woodlands, heathlands, gardens and a small number of nurseries principally in South West UK; however there have also been findings in Scotland, Ireland and New Zealand. Historic records suggest it has been in New Zealand since at least the 1950s. Why the concern and what are the hosts? P. kernoviae was first detected during official surveys for another plant pathogen, Phytophthora ramorum. P. kernoviae was causing extensive leaf blight and dieback PLANT DISEASE FACTSHEET of rhododendron and large necrotic, occasionally bleeding cankers on several beech trees. The pathogen is also causing damaging symptoms to bilberry (Vaccinium myrtillus) in heathland and woodland. Ornamental plants and trees in historic managed gardens have also become infected. The extent of the damage to trees, shrubs and heathland plants and the apparent speed of infection at the affected sites show that this pathogen is a serious threat to woodland, heathland and garden environments.

    JOURNAL OF AGRICULTURAL RESEARCH DEPARTMENT OF AGRICULTURE VOL. V WASHINGTON, D. C, OCTOBER II, 1915 No. 2 PERENNIAL MYCELIUM IN SPECIES OF PERONOSPO- RACEAE RELATED TO PHYTOPHTHORA INFES- TANS By I. E. MELHUS, Pathologist, Cotton and Truck Disease Investigations, Bureau of Plant Industry INTRODUCTION Phytophthora infestans having been found to be perennial in the. Irish potato (Solanum tvherosum), the question naturally arose as to whether other species of Peronosporaceae survive the winter in the northern part of the United States in the mycelial stage. As shown in another paper (13),1 the mycelium in the mother tuber grows up the stem to the surface of the soil and causes an infection of the foliage which may result in an epidemic of late-blight. Very little is known about the perennial nature of the mycelium of Peronosporaceae. Only two species have been reported in America: Plasmopara pygmaea on Hepática acutiloba by Stewart (15) and Phytoph- thora cactorum on Panax quinquefolium by Rosenbaum (14). Six have been shown to be perennial in Europe: Peronospora schachtii on Beta vtUgaris and Peronospora dipsaci on Dipsacus follonum by Kühn (7, 8) ; Peronospora alsinearum on Stellaria media, Peronospora grisea on Veronica heder aefolia, Peronospora effusa on S pinada olerácea, and A triplex hor- tensis by Magnus (9); and Peronospora viiicola on Vitis vinifera by Istvanffi (5). Many of the hosts of this family are annuals, but some are biennials, or, like the Irish potato, are perennials. Where the host lives over the winter, it is interesting to know whether the mycelium of the fungus may also live over, especially where the infection has become systemic and the mycelium is present in the crown of the host plant.
